Seal Materials

Code Designation Material Applications
V Virgin PTFE Virgin 100% PTFE- Our standard seat material. Ideal for most sanitary
polytetrafuoroethylene services. Specifed for applications requiring a low co-effcient of
friction.
Food Grade Material
G RTFE 15% glass reinforced 15% glass flled + 85% PTFE - Slightly higher temperature and
tetrafuoroethylene pressure rating than PTFE. Specifed for applications requiring
higher cycle life than PTFE.
Food Grade Material
C 25% Carbon PTFE 25% carbon reinforced 25% carbon +75% PTFE - Specifed for higher temperature
tetrafuoroethylene pressure applications. Ideal for steam and thermal fuid
applications. Higher cycle life than RTFE.
S Stainless Steel PTFE 50% stainless steel flled 50% stainless steel + 50% PTFE - Specifed for higher
tetrafuoroethylene temperature pressure applications in a sanitary process.
Food Grade Material
U UHMW Ultra-high molecular weight Specifed for its low modulus of abrasion and minimal property
polyethylene degradation when exposed to moderate levels of radiation. Ideal
for applications where fuorocarbons are not acceptable.
