Hayward SuperPump Cover Gasket SPX1600S — Replacement strainer cover seal for SP1600-SP1621, OEM fit, prevents leaks

The Hayward SPX1600S cover gasket replacement restores a watertight seal on Hayward SuperPump housings quickly and affordably.

If your SuperPump is showing signs of leakage around the strainer or you’re doing routine maintenance, this OEM-style cover gasket gives you the correct fit and sealing surface to keep circulation efficient. Designed to match the original profile, the gasket helps preserve pump performance by preventing water loss and debris ingress at the strainer cover interface.

How does this gasket solve common pool pump leakage?

Worn or compressed gaskets allow water to escape and let air into the pump basket chamber, which can reduce prime and cause cavitation. Replacing the old gasket with a properly sized SPX1600S gasket restores the sealing surface and minimizes leaks without altering pump operation.

• Replaces flattened or cracked seals that cause visible drips.
• Restores uniform compression for an even seal around the strainer cover.
• Prevents air entry that can interrupt prime and reduce flow.

Which SuperPump models will this cover gasket fit?

This gasket is manufactured to fit a range of Hayward SuperPump models, matching the original part dimensions to ensure a snug fit. Verify compatibility with your model number before installation to avoid fit issues.

• Compatible models include SP1600X5, SP1605X7, SP1607X10, SP1608X10.
• Also fits SP1610X15, SP1611X15, SP1615X20, and SP1616X20.

What should I inspect and prepare before replacing the gasket?

Before installing the new SPX1600S gasket, clean the mating surfaces and inspect the strainer cover and housing for cracks or warping. Proper preparation ensures a uniform seal and extends the life of the new gasket.

• Drain or isolate pump per safety guidelines and remove strainer cover.
• Clean old gasket residue, dirt, and mineral buildup from both sealing faces.
• Check the cover threads and hand knobs for damage; replace any broken hardware.

How easy is the replacement process for a DIYer?

Replacing the cover gasket is a straightforward maintenance task that most pool owners can complete with basic tools. Removing the strainer cover, seating the new gasket evenly, and reassembling the cover are the main steps.

• Tools required: flat screwdriver or gasket pick, clean rag, and possibly a small lubricant.
• Remove four bolts or use the swing-away hand knobs on compatible models for quicker access.
• Seat the gasket evenly and hand-tighten cover to avoid pinching or misalignment.

It’s ideal for pool owners doing their own maintenance, pool service technicians seeking a reliable replacement part, or anyone replacing worn seals to maintain pump efficiency. Choosing the right gasket helps protect the pump internals, keeps flow consistent, and prevents small leaks from becoming larger service issues.
