Hayward PSXVZ2A PSV Valve Key & Cover O-Ring Kit (4-Piece Seal Kit)
The Hayward PSXVZ2A is a genuine OEM key & cover O-ring replacement kit for Hayward PSV series diverter valves and select Hayward check valves that use PSV-style covers. This kit replaces the primary O-rings/seals that help prevent leaks at the valve cover and key/shaft area during normal operation.
Fits / Compatibility
- Hayward PSV Series diverter valves (key/cover seal applications)
- Commonly used on Hayward PSV / PSCV style valve bodies (diverter and certain check valve configurations)
Tip: Confirm your valve is a PSV-style valve (model on the valve body or parts diagram) before ordering, since seal kits vary by valve family.
What’s Included (4-Piece Kit)
- (1) Cover gasket / seal
- (2) O-rings (key/cover sealing)
- (1) O-ring (additional internal/cover sealing)
What It Fixes
- Water seepage or drips around the valve cover
- Minor leakage at the key/shaft area
- Flattened, cracked, or brittle O-rings discovered during valve service
- Preventive maintenance when rebuilding a PSV diverter/check valve
Installation Notes
- Shut off the pump and relieve system pressure before opening any valve.
- Clean the O-ring grooves and sealing surfaces before installing new seals.
- Lightly lubricate O-rings with a silicone-based pool lubricant (do not use petroleum-based products).
- Reassemble evenly—avoid pinching O-rings by tightening hardware uniformly.

Maintenance Tips
- If you service a valve cover, replace the seals while it’s open—reusing flattened O-rings is a common cause of repeat leaks.
- Keep valves protected from direct sun when possible to slow plastic and seal aging.
- If a valve is hard to turn, don’t force it—inspect the key/cover area and seals for swelling, debris, or wear.
- Check for small drips after reassembly and re-seat/retighten evenly if needed.
