Frequently Asked Questions

It seals the interface at the top of the pump sleeve to prevent fluid bypass, helping the sprayer build and hold pressure consistently.

Yes. Some catalogs include a hyphen (164-480), but both numbers refer to the same PTFE Gasket.

Match the displacement pump part number in your model’s parts manual. If that pump’s bill of materials lists 164480, you have the correct gasket.

Replace during pump service or if you notice pressure loss, fluid seepage past the sleeve, or difficulty priming after checking other wear parts.

PTFE (Teflon) resists aggressive solvents and reduces friction, improving sealing life in high-pressure, high-cycle applications common to professional airless sprayers.
