Model NO.: PTU, PTA, PTB Application: Hydroseal Performance: Corrosion Standard: Standard, Nonstandard Spring Shape: U Shape/Vshape/H Shape/O Shape, etc Certificate: ISO 9001, SGS Trademark: DEF Origin: Guangdong, China ( Mainland) Material: PU Type: Rotary Seal Shape: O-Ring Style: Floating Seal Function: Shaft Sealing Color: White, Blue, Black, Yellow Specification: SGS, ISO 9001 HS Code: 8484100000 Product description
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.
