Butterfly Valve Seats available in EPDM, FKM, & Silicone

Butterfly Valve Seats

Butterfly valve seats

We offer replacement seats for our butterfly valves in the 3 most common materials: Silicone, EPDM, and FKM (a Viton analog not FDA approved). Each seat will fit the respective valve size and series in both trigger and pull handle variants as the valve bodies are identical. With a few simple tools, replacing the valve seat is an easy proposition.

What type of material should I use?

While we are prohibited from recommending a gasket type, we do offer a Chemical Resistance Chart (new window) that matches the resistance level of gasket materials to the different chemicals / food products you may be using. We may suggest using an A- or B-rated gasket for your particular application.

Warning: Valve seats are designed to fit Glacier Tanks sanitary butterfly valves only. We cannot guarantee they will fit other manufacturers, and once purchased, valve seats are non-returnable per FDA regulation.
