SpaShopper offers the PS-3867 premium Viton carbon graphite pump seal, engineered for superior salt and ozone resistance. This better-grade seal serves as the enhanced alternative to the standard PS-200, designed specifically for Aqua-Flo wet end assemblies and Waterway "Viper" models.

Precise Dimensions: Both the spring seal component and the ceramic/rubber section measure 1 1/4" across. The shaft opening on each part is approximately 5/8" in diameter. The spring-loaded portion mounts directly onto your impeller shaft, while the ceramic and rubber component seats securely into the volute or wet end housing.

Installation Guidelines: Apply silicone sealant to the impeller shaft before gently sliding the spring seal into position. A thin layer of silicone on the rubber component will help it glide smoothly into the volute body for a proper fit.

Important Compatibility Note: This PS-3867 seal is exclusively used in Waterway "Viper" and EX2 wet end models. Other Waterway wet end configurations require the Better 1000 seal design instead.
