Compatible Booster Pump Gasket

This Viton O-ring is a drain component built for booster pumps from Flint & Walling. It fits Grainger part ranges 22W727 to 22W737 and 2PC42 to 2PC48. Additional coverage includes 4YC09 to 4YC12 and the PB pump series listed by the manufacturer.

Chemical Resistance Limits

Viton material resists many oils, fuels and high-temperature fluids found in booster pump service. It is not suited for strong bases, polar solvents or steam above its rated range. The gasket performs only within the chemical and thermal limits of the host pump design.

Verify Pump Model Before Ordering

Confirm your booster pump carries a Flint & Walling nameplate and matches one of the Grainger or PB part numbers shown. Cross-reference the exact model such as PB0512S051 or PB2714S303. Installations on unlisted pumps will not seal correctly.

What does the Viton material mean for daily use?

Viton resists heat, oils and many chemicals better than standard rubber, so the seal lasts longer in hot or aggressive water conditions

Is this a standard pipe-thread size or a proprietary seal?

It is a proprietary O-ring for the listed Flint & Walling booster pumps, not a universal pipe-thread gasket
