A pool pump lives a tough life, sitting in damp air, getting splashed, and running on long summer cycles. The plugs feeding it need to keep up. Finding the right fit means thinking about sealing parts that stop slow leaks, electrical safety, and the kind of outlet you’re working with at the equipment pad.
This roundup covers the practical angles: replacement drain plugs, sealing O-rings, chlorinator connection parts, and GFCI safety assemblies that protect you from ground faults. Anyone running a Pentair system or anyone wiring a pump near water will find something useful below.
The Shortlist At A Glance
27001-0061S O-Ring for Pentair Sta-Rite Filter
OAONAN GFCI Replacement Plug Assembly 15 Amp
192115 Drain Plug O-Ring for Pentair
Pool Chlorinator Parts for Pentair Rainbow 320/322
ELEGRP G1215PA2 Auto-Monitoring GFCI Plug
DEWENWILS 3 FT GFCI Extension Cord Outdoor
Pool Pump Drain Plug 071131 for Pentair
Why These Options Stand Out
Tank O-rings are easy to ignore until one fails. The 27001-0061S replacement gasket from Pulems fits Pentair Sta-Rite PLM and PLD series filter tanks, including common sizes from PLM100 up through PLM300 and DE filter tanks in the PLD50 and PLD70 range. For anyone who services their own filter, a worn or hardened O-ring is usually the first suspect when water shows up under the tank base.
Unlike the drain-plug O-rings reviewed later, this one handles the much larger tank-to-base interface, where a slow leak can go unnoticed for weeks. Replacement is straightforward once the tank is opened for a media change. In our view, keeping a spare on hand prevents the kind of mid-season dribble that stains concrete pads.
The Upside
- Covers a wide range of Sta-Rite filter models, from PLM100 through PLM300
- Fits both PLD50 and PLD70 DE filter tanks in one gasket
- Direct compatibility with the standard 27001-0061S part reference
- Simple swap during routine filter maintenance
Honest Caveats
- Only fits Sta-Rite systems, not universal across pool equipment brands
- Requires opening the filter tank to access, so a full service is part of the job
- Like most rubber gaskets, owners commonly report the material stiffens with age and benefits from regular inspection

Look Elsewhere When
Anyone running a different filter brand such as Hayward or Jandy should skip this gasket and match the OEM number on their own tank instead.
A GFCI plug, or ground fault circuit interrupter, cuts power in milliseconds when it senses current leaking through water or a person. The OAONAN 15-amp replacement plug is built for exactly the kind of equipment that lives in damp spaces: pressure washers, hot tubs, air conditioners, and pool-side appliances. Wiring it up means matching the three leads to clearly marked BLK, GRN, and WHT screw terminals.
The auto-reset feature is a practical touch, since brief power blips can otherwise leave a pump dead until someone walks out to press the button. Compared with the basic hardwired plug that came on older pumps, this one adds a layer of protection without needing a panel upgrade.
Strengths Worth Knowing
- Built-in surge and lightning protection rated to handle 6 kilovolts of spike
- Three-prong grounded design suited to standard 15-amp pump circuits
- Auto-reset function restores power without a manual press after a trip
- Clear terminal markings (BLK, GRN, WHT) simplify the wiring step
Things To Consider
- Auto-reset behavior is helpful but means the pump may restart on its own after a trip
- Wiring work requires basic comfort with a screwdriver and wire stripper
Who Should Grab It
Owners of older hot tubs, spas, and pool pumps without integrated GFCI protection who want a practical safety upgrade at the plug.
Reach For A Different Pick When
Anyone with a pump that already has a built-in GFCI or runs on a GFCI breaker should consider the DEWENWILS GFCI extension cord instead for added reach.
The 192115 (also sold as 192115Z) is the small rubber gasket that seals Pentair 071131 and 357161 drain plugs. It is a tiny part, but the slow trickle it prevents shows up as a wet pad under the pump and, over time, a mineral stain that is hard to buff out. Pulems offers this replacement as a direct fit for the OEM reference, so there is no measuring required.
For anyone winterizing or doing a water-change service, swapping the O-ring while the plug is out is the kind of two-minute job that prevents the next puddle. Compared with the larger Sta-Rite tank O-ring covered earlier, this one handles the much smaller drain-plug interface where leaks tend to drip directly onto concrete.
Benefits That Matter
- Direct cross-reference to Pentair 192115 and 192115Z part numbers
- Also known as the O-130 sizing, helpful when cross-shopping at local suppliers
- Restores a clean seal on 071131 and 357161 drain plugs
- Low-cost spare that pays for itself the first time a leak shows up
Trade-Offs To Consider
- Specific to Pentair drain plugs, not a universal pool-pump gasket
- Rubber compound hardens over time, so even unused spares have a shelf life

Swap It Out When
Anyone replacing the full drain plug should look at the Pulems 071131 drain plug kit, which includes a fresh O-ring already fitted.
Chlorinator feeders, the inline canisters that dissolve chlorine tablets into the circulation loop, wear out at the connection points long before the body gives up. This Pulems kit covers three common failure spots on the Pentair Rainbow 320 and 322: the R172272 NPT 90-degree connector, the R172091 tube support, and the R171097 tube support. Together they handle the tubing run that carries treated water back into the pool.
For pool owners who already know their Rainbow model number, the kit is a sensible preventive replacement during a slow season. Unlike the safety-focused plugs reviewed above, these parts keep chlorine feeding reliably rather than protecting against electrical faults.
Bright Spots
- Three-part bundle covers the most common Rainbow 320 and 322 connection points
- Direct cross-reference to OEM part numbers R172272, R172091, and R171097
- 90-degree NPT connector handles tight equipment-pad layouts
- Helps restore consistent chlorine distribution into the circulation loop
Less Ideal Details
- Specific to Rainbow 320 and 322 models, not a generic chlorinator rebuild
- Tube supports can crack if over-tightened during installation
Whose Shelf It Belongs On
Owners of Pentair Rainbow 320 or 322 chlorinators with a known drip at the fittings or brittle tubing supports.
A Better Fit Elsewhere
Anyone running a different chlorinator brand should match the OEM part number on their existing unit rather than adapting this Rainbow-specific kit.
The ELEGRP G1215PA2 takes the standard GFCI replacement plug and adds constant self-monitoring. The unit runs an internal check every five seconds to confirm the ground-fault protection circuit is still working, which goes well beyond the typical three-hour self-test interval. For pool-side equipment where a failed GFCI could go unnoticed for months, that is a meaningful upgrade.
This is the non-grounded two-wire, two-prong variant, so it suits older pumps without a ground wire in the cord. Compared with the OAONAN plug covered earlier, this one trades the three-prong grounded format for a more frequent self-test cycle and lower standby power draw.
Positive Takeaways
- Patented self-test runs every five seconds, far tighter than the standard three-hour interval
- Auto-reset behavior restores protection after a trip without manual intervention
- Low standby power consumption suits equipment that runs long seasonal cycles
- 15-amp rating matches typical residential pool pump circuits
Room For Improvement
- Two-prong non-grounded format only fits older pumps without a ground lead

Where A Sibling Pick Shines
Anyone with a three-prong grounded pump cord should pick the OAONAN GFCI plug instead, since it matches the grounded format.
Sometimes the wall outlet sits just out of reach of the pump, and stretching a cord across a wet pad is asking for trouble. The DEWENWILS 3-foot outdoor GFCI extension cord solves the reach problem while adding ground-fault protection in the cord itself. The 12/3 SJTW build is rated for outdoor use, with a thick 600V insulation jacket that handles rough runs along concrete.
The built-in LED on the GFCI plug lights up when power is flowing, a small detail that saves a trip to the breaker panel when troubleshooting. Compared with the plug-in GFCI assemblies reviewed above, this one moves the protection out to a short, heavy-duty cord segment suited to a tight equipment pad.
Notable Upsides
- 12/3 SJTW cable rated for outdoor exposure and heavy-duty use
- 15-amp, 125-volt rating handles standard pool pump loads
- LED indicator on the GFCI plug shows power status at a glance
- Auto-reset function restores protection after a power interruption
Points To Note
- 3-foot length is short by design, so it only solves tight reach problems rather than long runs

Consider Something Else When
Anyone needing a longer run across the yard should look for a full-length outdoor GFCI cord rather than relying on daisy-chained short cords.
The 071131 drain plug from Pulems comes with a fresh 192115 O-ring already fitted, so it lands as a complete service part rather than a bare plug. The 1/4-inch male thread matches Pentair Whisperflo, Intelliflo, and SuperFlo inground pumps, plus a wide range of Vf and Vs variants in the Intelliflo line. For anyone winterizing or replacing a stripped plug, this is the kind of part that closes the job in one stop.
Compared with the standalone O-ring reviewed earlier, this kit includes the plug itself for cases where the old one is damaged or lost. Owners commonly report that the included O-ring seats cleanly on the first install, which is what most people want from a service part.
What Earns Its Place
- Comes with a fresh 192115 O-ring already fitted to the plug
- Fits Pentair Whisperflo, Intelliflo, and SuperFlo pump families
- Also matches Intelliflo Vf, Vs 3050, and Vs-SVRS variants
- One-piece service kit reduces the chance of a leftover old O-ring causing a leak
Potential Drawbacks
- Specific to Pentair 071131 thread pattern, not a universal replacement

Not Your Match When
Anyone with a different pump brand should match the OEM drain plug reference on their existing unit, since 071131 is Pentair-specific.
Matching Plugs and Seals to Your Equipment
The right plug depends on the part of the system that needs attention. Sealing parts like the 27001-0061S Sta-Rite O-ring and the 071131 drain plug handle leaks at gasketed joints, while chlorinator fittings like the Rainbow 320/322 kit keep chemical feed lines connected. Electrical safety parts split between in-line GFCI plugs and outdoor extension cords, each solving a different reach or wiring problem.
Start by identifying the equipment brand and the exact failure point. Pentair owners can usually cross-reference OEM part numbers like 192115, 071131, or R172272 directly. For pumps without built-in GFCI protection, an in-line plug or short outdoor cord adds the safety layer without a panel upgrade.
Why Material Compatibility Matters
Rubber compounds age differently depending on water chemistry. High chlorine levels and salt systems both shorten O-ring life compared with freshwater pools, so a yearly visual check catches hardening before a leak starts. Matching the OEM part number, not just the size, prevents the wrong durometer (a measure of rubber firmness) from seating improperly under pressure.
For electrical parts, the difference between grounded three-prong and non-grounded two-prong plugs is not interchangeable. Older two-wire pump cords need a matching GFCI plug like the ELEGRP G1215PA2, while modern grounded cords need the OAONAN format. The wrong format simply will not seat.
Reading GFCI Specs Without the Jargon
A GFCI’s job is to cut power within milliseconds when current leaks to ground, which is exactly what happens when water enters a pump housing. Self-test frequency matters because a GFCI that has failed silently leaves equipment unprotected. Look for plugs that self-test at least daily, and preferably every few hours, for unattended equipment pads.
Surge protection ratings tell a different story: a higher kilovolt rating means the plug can absorb a larger voltage spike from a nearby lightning strike or grid event without failing. For pool equipment exposed to outdoor wiring, anything below 6 kilovolts of surge tolerance is the bare minimum.
Matching the Reach and Load
A 15-amp rating covers most residential pool pumps, but a pump that draws close to that limit leaves little headroom. Heavier loads benefit from a heavy-duty 12-gauge cord like the DEWENWILS rather than a lighter 14-gauge option, since thinner cables run hotter under sustained draw. The 3-foot length is intentionally short to keep voltage drop low.
Smart Shopper Notes for Pool Pump Plug Replacements
Pitfalls Shoppers Hit
The most common slip is matching a part by physical size instead of OEM part number. Two drain plugs can look almost identical but use different thread pitches, which only becomes obvious at install. Always cross-reference the OEM number printed on the existing part or in the pump manual before ordering.
Another trap is assuming every pool-side plug needs GFCI protection. The protection may already live in the breaker panel, in which case adding a second GFCI in series causes nuisance trips during normal operation. Check the breaker label first, then decide whether the safety layer needs adding at the plug.
What The Higher Tier Buys
Stepping up to a constant-self-test GFCI plug buys faster detection of a failed protection circuit, which matters most on equipment that runs unattended for months. Premium extension cords add thicker insulation and LED status indicators that make troubleshooting faster when a pump will not start.
For chlorinator parts, a bundled kit with multiple fittings costs more upfront than a single replacement but prevents a second service call when the next weakest fitting fails a week later. The premium in this category is paid in fewer return trips to the equipment pad, not in any single feature that changes daily use.
