Product details
The Hayward SPX1425Z6 is the o-ring sold under the name SP-1425. Hayward describes it as the o-ring used in manufacturing prior to 1989 on Perflex filters.
Two readings on fit
The product description narrows this to pre 1989 Perflex manufacture. The Hayward parts breakdowns are broader, carrying the same o-ring for the S-200 and S-240 and Pro Series side mount sand filters, the ASL C850 and C1250 cartridge filters, the Perflex EC60 Series II and the EC65 through EC75 range, and Hayward skimmers. Both are listed above. Match the part number against the breakdown for your own unit rather than assuming.
Why it matters
An o-ring is a cheap part with expensive symptoms. A flattened, cracked or perished seal shows up as a drip, as air pulled into the system, or as a pump that will not hold prime, and no amount of tightening fixes it once the rubber has gone.
