Product Introduction
The Spring Energized PTFE Seal is a spring- energized, pressure-assisted sealing device consisting of a PTFE (or other polymer) seal partially encapsulating a corrosion-resistant metal spring energizer.
The PTFE jackets are precisely machined, filled with PTFE composites and other high performance polymers, function at temperatures ranging from cryogenic to 250 C and inert to almost all chemicals. Some types also can be used in sanitary environment.
Seals are available with a variety of spring energizers, each having characteristics to meet specific requirements. Spring loading can be adjusted to meet critical low or extremely high requirements in dynamic applications.

For Symmetric, for Rod, for Piston are available.
Material
Virgin PTFE, PTFE filled
Color
