Hayward SPX2700Z4 Strainer Cover O-Ring

What This Part Is Used For
The Hayward SPX2700Z4 is a strainer cover O-ring used to seal the pump lid to the strainer housing on compatible Hayward pumps. It sits in the lid groove and keeps the suction side airtight so the pump can prime and run steadily. This is a routine maintenance seal.

Why This Part Matters
A flattened or cracked O-ring lets air into the pump and causes bubbles in the pump basket. That can lead to poor priming, weak flow, and noisy operation. Replacing the O-ring restores suction integrity and stabilizes circulation.

Installation and Fitment Guidance

About the Hayward Brand
Hayward builds integrated pool equipment systems including pumps, filters, heaters, automation, cleaners, and chlorination products. Reliable suction sealing is critical for stable pump performance and proper filtration. Simple service parts like O-rings prevent prime loss and nuisance air leaks. Genuine Hayward parts help keep fit consistent across common installations.

Common Service Context
Technicians replace this O-ring when they see bubbles returning to the pool or the pump struggles to prime after basket cleanings. It is also common at spring start-up after seals dry out over winter.
