A pool pump only moves water as well as the hardware bolted to it. Outlets, elbows, gaskets, and adapters decide whether your setup leaks, primes, or quietly does its job. The right match depends on your filter model, hose size, and whether you run an Intex, Coleman, or a full-size Hayward system. Below, eight parts cover the most common outlet connection points on residential pool gear, sorted by the kind of repair or upgrade you’re chasing.
A Side-By-Side Look
CVILL P6H1317 Pool Inlet and Outlet Filter
GAME 40mm to 1.5-Inch Pool Hose Adapter Kit
Pool Ruler DEX2400Z5 O-Ring Two Pack + Lubricant
Fairooth 40mm to 1-1/2″ Adapter Kit, 4 Pack
Hayward DEX2400Z5 Outlet Elbow O-Ring
Hayward CX3020FB Outlet Elbow Replacement
RTPOWER Lay-Z-Spa Water Pump Seal Rebuild Kit
UASAM 11238 Surface Skimmer Hose B Adapter
Inside Each Recommended Option
The CVILL P6H1317 is a threaded strainer that doubles as an inlet or outlet fitting on compatible above-ground pool plumbing. The 2.5-inch threaded end lands on plunger valves commonly found on Intex and Coleman setups, with a 1.5-inch hose barb on the other side. That two-way design cuts down on stocking separate parts, which is a quiet relief for anyone managing seasonal pool teardowns.
You’ll spend less time guessing which filter goes where during spring opening, since the same part slots into both sides of the loop. Pool owners juggling replacement parts between seasons may find the dual-role fit especially helpful for keeping a single spare on hand.
Points In Its Favor
- Works as either inlet or outlet strainer, reducing spare-part clutter.
- Threaded 2.5-inch connector suits standard above-ground plunger valves.
- 1.5-inch hose tail fits common flexible pool hose diameters.
- Strainer mesh helps catch debris before it reaches the pump impeller.
Things To Consider
- Mesh requires periodic rinsing to maintain flow on heavily used pools.
- Plastic threads can cross-thread if forced at an angle during reinstallation.
Who It Suits Best
Owners of Intex or Coleman above-ground pools who want one strainer part that works on both sides of the plumbing loop.
Where Another Pick Suits Better
Hard-plumbed Hayward DE systems with a leaking outlet elbow are better served by the Hayward DEX2400Z5 O-Ring, which targets that specific filter housing.
Mixing Intex pool hose ends with a third-party filter usually means a mismatch at the threaded port. The GAME adapter conversion kit bridges that 40mm outlet or inlet to a standard 1.5-inch hose, sold as a pack of two. Each adapter is plastic, so it stays light and easy to position by hand. The “1 1/4 inch or 1 1/2 inch” sizing covers the two most common flexible hose widths on residential setups.
It’s a small part that solves a stubborn problem when you’re blending brands during a filter upgrade. You may find the pack-of-two format useful for tackling both the inlet and outlet at the same time without a second trip to the product page.
Useful Strengths
- Two adapters per pack handle both inlet and outlet hookups in one purchase.
- Accepts 1-1/4-inch or 1-1/2-inch hose for flexible compatibility.
- Lightweight plastic makes hand-tightening simple during installation.
- Lets a non-Intex filter pair with Intex-style 40mm ports.
Honest Caveats
- Plastic body may not match the longevity of brass or stainless alternatives.
- Hose clamps at the barbed end are typically required to prevent slow weeping at pressure.
Made For
Shoppers connecting an Intex-style pool to a non-Intex filter or pump that uses 1.5-inch threaded ports.
A Better Fit Elsewhere
Anyone rebuilding a Coleman Lay-Z-Spa pump should look at the RTPOWER Seal Rebuild Kit, since the GAME kit is for hose conversion, not seal service.
An outlet elbow gasket is the kind of part you only think about when water starts creeping under the filter tank. The Pool Ruler kit ships two DEX2400Z5-equivalent O-rings plus a small tube of silicone lubricant, covering Micro-Clear, Pro-Grid D.E., SwimClear, and HCF cartridge filter families. The cross-brand fit list is unusually wide for a small rubber ring.
That dual-pack is genuinely useful: one ring goes in service, and the second sits on the shelf until the next teardown. Pool owners maintaining older Hayward gear may find the included lubricant saves a separate parts run.
Benefits That Matter
- Silicone lubricant included so the new ring seats cleanly without tearing.
- Two-pack design means a backup gasket stays on hand for the next service.
- Compatible with multiple Hayward filter lines, including D.E. and cartridge.
- Drop-in fit for Aladdin O-24 equivalents, simplifying cross-brand swaps.
Worth Noting
- Only fits outlet elbow locations, so it cannot substitute for pump lid or union gaskets.
- Model compatibility must be confirmed against your filter serial plate before ordering.

Look Elsewhere When
If the entire elbow body is cracked, the Hayward CX3020FB Outlet Elbow Replacement is the right call, since a new O-ring will not fix a broken housing.
The Fairooth kit ships four 40mm-to-1.5-inch adapters, four O-rings, four gaskets, and a roll of thread tape, all in gray PVC plastic. That full bundle covers inlet and outlet hookups on both ends of a pump-to-filter loop, with extras left for the next seasonal changeover. Threaded joints benefit from the included tape during assembly.
Compared to the GAME two-pack covered earlier, this Fairooth set is geared toward full above-ground conversions where multiple hose-to-pump joints need attention at once. Depending on your setup, the spare adapters can earn their keep as replacements after a few seasons of UV exposure.
Practical Pluses
- Four adapters, gaskets, and O-rings let you complete inlet and outlet work in one session.
- PVC plastic body resists corrosion from chlorinated pool water.
- Thread tape included for sealing tapered connections on assembly.
- Sized for 40mm to 1-1/2-inch transitions, a common above-ground combo.
Points To Note
- Extra adapters may be unnecessary for owners who only need a single connection.
- Color and minor dimensions can shift slightly between production runs.
Whose Shelf It Belongs On

Another Choice May Suit
Shoppers with a single hose-to-pump mismatch are better served by the GAME 2-pack, which avoids paying for unneeded extras.
This is the OEM Hayward outlet elbow O-ring for Pro Grid vertical D.E. models DE2420, DE3620, DE4820, DE6020, and DE7220, and it also fits the Micro-Clear vertical grid D.E. line. The gasket carries the genuine Hayward branding, which matters for owners who want a confirmed factory-spec replacement during seasonal service. Weighing in around 3 pounds shipped, it lands as a small but deliberate part.
The trade-off shows up in pricing, since OEM Hayward parts generally cost more than third-party equivalents like the Pool Ruler kit covered earlier. Depending on your comfort level with aftermarket gaskets, that premium may or may not feel justified.
Bright Spots
- Genuine Hayward factory part for confident compatibility.
- Confirmed fit across five Pro Grid vertical D.E. tank sizes.
- Also works with Micro-Clear vertical grid D.E. filters.
- Single-piece replacement keeps service focused on the failed seal.
Trade Offs
- Costs more than multi-fit third-party O-rings like the Pool Ruler set.
- Single ring, so a second spare is not included in the box.
The Right Fit
Pro Grid vertical D.E. owners who prefer factory-branded gaskets and have confirmed the model number on their filter label.
Swap It Out When
Budget-focused pool owners maintaining older Hayward tanks get more value from the Pool Ruler two-pack, which covers similar filters at a lower cost.
Sometimes the O-ring is fine and the elbow itself is the problem. The Hayward CX3020FB is a full outlet elbow assembly designed for the SwimClear cartridge filter line, sold as a genuine Hayward replacement part. It threads onto the existing manifold and accepts the same hose or plumbing connection as the original.
This is the part to reach for when the plastic body has cracked from age, freeze damage, or a stuck union. You may find the swap takes longer than a gasket service, since the whole fitting unwinds from the filter tank.
Useful Highlights
- Full elbow assembly replaces cracked or stripped housings outright.
- Factory Hayward part keeps SwimClear service work within spec.
- Threads into existing manifold without needing a new gasket in most cases.
- Suits cartridge filter owners who prefer a complete fitting over a patch.
Small Caveats
- Limited to SwimClear cartridge filter models only.
- Cost is higher than a basic O-ring swap when only the gasket has failed.

Skip It When
Service work is limited to a leaking gasket, since the Pool Ruler DEX2400Z5 O-Ring set covers that repair for less.
Inflatable spas take more abuse from setup cycles than most people expect, and the pump seals are usually the first thing to weep. The RTPOWER rebuild kit targets the Coleman Lay-Z-Spa water pump with two pump outlet O-rings, one pump inlet O-ring, one pump gasket, two blower non-return check valve seals, plus connector seals for ports A, B, and C. Six 304 stainless steel body screws and lock nuts round out the bundle, so corroded factory hardware gets replaced at the same time.
It’s a deeper service than a simple O-ring swap, which is why this kit suits owners comfortable disassembling the pump housing. You may find the stainless hardware alone worth the kit if your existing screws have started to rust.
Real-World Strengths
- Complete seal bundle covers outlet, inlet, gasket, and non-return valves in one box.
- 304 stainless steel replacement screws resist rust in damp spa environments.
- Targets the Lay-Z-Spa pump specifically, reducing fit guesswork.
- Saves buying each seal separately across multiple parts orders.
Areas To Watch
- Disassembly of the Lay-Z-Spa pump is required, which can be intimidating for first-timers.
- Only fits Coleman Lay-Z-Spa pumps, so it is not a cross-brand rebuild kit.
Who Should Grab It
Lay-Z-Spa owners seeing air in the lines, water around the pump, or a pump that will not hold prime through a full cycle.
Not Your Match When
The issue is at the hose connection rather than the pump body, since the UASAM 11238 Surface Skimmer Adapter handles Intex hose-side repairs instead.
The Intex 11238 surface skimmer hose adapter sits between the wall-mounted skimmer and the filter hose, with a poolside connection around 3-1/4 inches inside diameter. The UASAM reproduction targets that specific skimmer fitting so water can move from the skimmer basket into the pump loop. It’s a niche replacement, but a useful one when the original plastic adapter cracks or warps from sun exposure.
It’s the kind of part you only need once, and the only time you search for it is when the skimmer stops pulling debris. Depending on your climate, UV-rated plastic bodies tend to outlast bargain-bin alternatives that come bundled with new pools.
Reasons It Performs
- Direct-fit replacement for Intex 11238 surface skimmer connections.
- Restores water flow from wall skimmer into the filter hose.
- Sized for Intex wall-mount and Deluxe maintenance kit skimmers.
- Useful spare to keep with seasonal pool gear.
Practical Considerations
- Specific to Intex skimmer models, so it does not fit other skimmer brands.
- Plastic body should be inspected each season for UV-related brittleness.

Picking The Right Outlet Hardware For Your Pool
Match The Part To Your Filter Or Pump
Before ordering any outlet part, jot down the model number printed on your filter tank or pump label. Hayward D.E. owners usually need either a DEX2400Z5 O-ring or a CX3020FB elbow assembly, while SwimClear cartridge owners fit a different elbow entirely. Intex and Coleman above-ground setups typically work with 1.5-inch threaded ports or 40mm hose barbs. Matching the exact model up front avoids the most expensive mistake in this category: returning the wrong part twice.
Check Hose Diameter And Thread Standard
Two measurements drive fit: the hose inner diameter and the threaded port size on the pump or filter. 1-1/4-inch and 1-1/2-inch hoses cover most above-ground pools, while 40mm ports show up on Intex-style connections. Mixing the two without an adapter leads to slow leaks, low flow, or a pump that never primes. The adapter kits reviewed above exist for exactly this translation step.
Buy Spares For Seasonal Service
Gaskets and O-rings are wear items, not lifetime components. A small silicone-lubricated O-ring generally lasts a couple of seasons, while UV-exposed plastic adapters can crack sooner in hot climates. Picking up a two-pack or a four-pack puts a backup on the shelf, so a mid-summer leak does not turn into a multi-day wait for a replacement.
Common Shopping Slip Ups And Upgrade Tradeoffs
Pitfalls Shoppers Hit
The most common error is matching by appearance rather than model number, since many outlet elbows and adapters look interchangeable but use different thread pitches. Another slip is forgetting thread tape on tapered plastic connections, which leaves a slow drip that often shows up the next morning. Skipping a spare O-ring is the third trap, because seal failures rarely give a warning before they let go.
When Paying More Pays Off
Spending more on a genuine Hayward elbow or OEM O-ring tends to make sense on tanks older than five years, where aftermarket parts can fit loosely and cause recurring weep. Stainless hardware upgrades on a Lay-Z-Spa rebuild also pay off in damp storage conditions, since plain steel screws rust fast. The premium rarely matters on a brand-new pump, where the original factory seals still have plenty of life left.
Frequently Asked Questions
How do I know which outlet part fits my pool pump?
Check the model number on the pump or filter label, then match it against the compatibility list in the product description. Above-ground pools usually use 1.5-inch threaded ports, while Intex-style setups often use 40mm hose barbs.
Can I use one O-ring part across different filter brands?
Some third-party O-rings like the Pool Ruler DEX2400Z5 kit list multiple Hayward filter families, but you still need to confirm the model number. Cross-brand fit is rarely universal, even when seals look identical.
When should I replace the whole outlet elbow instead of just the O-ring?
Replace the full elbow when the plastic body is cracked, stripped, or visibly deformed. A simple O-ring swap handles most routine leaks, but a damaged housing needs the full fitting.
Are plastic outlet adapters safe under pump pressure?
Quality plastic adapters rated for pool use handle typical residential pump pressures when properly clamped and taped. Stainless or brass fittings last longer under heavy thermal cycling, but plastic is acceptable for most above-ground setups.
How often should outlet O-rings be replaced?
Most outlet O-rings last two to three pool seasons with silicone lubrication during installation. Inspect them at each seasonal opening, since UV and chloramine exposure shorten gasket life in warmer climates.
