China Polyester Filled PTFE Spring Energized Seals Symmetric Seal

Product Introduction
PTFE with Polyester Spring Energized 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.
