O-Ring Seal

Square Cross-Section Ring Seals. Same as FEP above plus:

PFA-encapsulated O-Rings (Perfluoroalkoxy). Same as FEP above but with these added benefits:

Teflon Encapsulated O-RingsTFE-O-SIL silicone, Viton? or EPDM O-Rings encapsulated with FEP or PFA are designed to address the growing problem of sealing in the most hostile chemical and temperature environments. TFE-O-SIL combines the best qualities of two materials, FEP or PFA on the outside with its chemical inertness and an elastomer on the inside for resilience. This unique combination forms a highly effective, long lasting seal for the most demanding applications.

TFE-O-SIL O-Rings are available in over 60 standard from .063" (1.60mm) to 1-1/4" (31.75mm). Standard TFE-O-SIL O-Rings are comprised of FEP over silicone, Viton?, or EPDM, and can be used in temperatures from -75
