Viton® elastomers resist degradation from chlorine, salt, and ozone far better than standard Buna-N seals, making this the ideal choice for pools with salt chlorine generators or ozone systems. The carbon-graphite primary ring and polished ceramic seat provide smooth, long-lasting operation under demanding conditions.

Pro Tip:

Verify shaft size with calipers before ordering to ensure proper fit.

Note: This compatibility chart is based on U.S. Seal Mfg. Pool & Spa Pump Products Cross-Reference Guide cross-reference data. Always verify pump model and part numbers before ordering. Some models may have multiple seal options depending on manufacture date and specific configuration.
