EXTREME-VS PTFE Coated Valve Stems
Long-Lasting PTFE Coated Valve Stems to Replace Buna, EPDM, and FKM for Maximum Durability
Buna, EPDM, and FKM valve stems are good for some applications, but for the most challenging applications, they just don’t cut it. They need to be constantly monitored and frequently replaced.
The new Extreme-VS stems solve this problem with solid PTFE sealing surfaces. This is not PTFE bonded to another elastomer. They are stainless steel with PTFE, and that’s it. This composition ensures lasting durability that cannot be found in other types.
In all applications, they are outlasting the standard stems, in some cases by 3-4 times the life span.
