Pool and Spa Drain Plug O-Ring, 2-Inch OD | APCO2392
APCO2392 is an aftermarket O-125 replacement O-ring commonly used to seal compatible pool and spa drain plugs, flush plugs, filter drains, float valves and 1-1/2-inch union or tailpiece connections.
The ring measures approximately 1-3/4 inches across the inside, 2 inches across the outside and 1/8 inch through the cross section. It cross-references several Hayward, Waterway, Pentair, Jacuzzi, Doughboy, American Granby and other pool-equipment part numbers.
This listing includes one replacement O-ring. The drain plug, union, tailpiece, valve, filter and other equipment components are not included.
Common Applications
- Pool and spa drain or flush plugs
- Hayward SP1022B and SP1022C plug applications
- Compatible filter drain assemblies
- Compatible 1-1/2-inch union tailpieces
- Waterway union and gate-valve connections
- Select float-valve and filter fittings
When to Replace the Seal
- Water drips from a drain plug or union
- The original O-ring is flat or compressed
- Cracks, cuts or splits are visible
- The ring is stretched, swollen or distorted
- The fitting requires overtightening to stop leaking
- The connection was opened and no longer reseals
Product Features
- Aftermarket replacement seal: Provides an economical repair option for equipment that specifies APCO2392, O-125 or one of the listed cross-reference numbers.
- Water-leak prevention: Compresses between compatible mating surfaces to help stop water from escaping around a plug, union, fitting or drain connection.
- Air-leak prevention: May help prevent air intrusion when used in a compatible suction-side union or fitting.
- Multiple equipment applications: The same O-ring dimensions are used across several brands and types of pool and spa equipment.
- Serviceable repair: Allows a worn seal to be replaced without replacing the complete plug, valve, union or filter assembly when the surrounding components remain undamaged.
- Exact dimensional match: Approximately 1-3/4-inch inside diameter, 2-inch outside diameter and 1/8-inch cross section.

- Clean dirt, scale and old lubricant from both sealing surfaces
- Inspect the plug, tailpiece and fitting for hairline cracks
- Confirm the replacement ring is not twisted or stretched
- Seat the O-ring evenly inside the intended groove
- Use only a light coating of pool-safe silicone lubricant if needed

Frequently Asked Questions
What is APCO2392?
APCO2392 is an aftermarket O-125 replacement sealing O-ring used in compatible pool and spa drain plugs, flush plugs, filter fittings and union connections.
What are the dimensions of APCO2392?
It measures approximately 1-3/4 inches inside diameter, 2 inches outside diameter and 1/8 inch through the cross section.
Does APCO2392 replace Hayward SPX1022CZ2?
Yes. APCO2392 is commonly listed as an aftermarket dimensional replacement for Hayward SPX1022CZ2 in compatible applications.
Does it replace Waterway 805-0224?
It is commonly cross-referenced with Waterway 805-0224. Confirm the equipment model and original parts diagram because Waterway uses the seal in several different locations.
Is this an OEM Hayward or Waterway O-ring?
No. This listing is for an aftermarket replacement O-ring designed to match the dimensions of the listed original part numbers.
Is the drain plug included?
No. This listing includes one O-ring only. Drain plugs, unions, tailpieces, valves and other equipment components are not included.
Can this O-ring be used on a 1-1/2-inch union?
It is used in several compatible 1-1/2-inch union and tailpiece applications. The nominal plumbing size does not equal the O-ring diameter, so the original part number should still be confirmed.
Why is the connection still leaking with a new O-ring?
Continued leakage may be caused by dirt on the sealing surface, a twisted O-ring, overtightening, plumbing misalignment or a cracked plug, union nut, tailpiece or fitting body.
Should silicone lubricant be used?
A very light coating of pool-safe silicone lubricant may help the ring seat without twisting. Do not use petroleum jelly or a petroleum-based lubricant.
Can the original O-ring be reused?
Reuse is not recommended when the old ring is flat, cracked, stretched, swollen, hardened or unable to reseal after the fitting has been opened.
Not Sure Which Pool Equipment O-Ring You Need?
Match the equipment model, original part number, inside diameter and cross-section thickness before selecting a replacement seal.
