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.
Material
PTFE filled with bronze(glass, graphite, carbon, etc. )
Application Example
Radial Seals in Static Service.
Radial Seals in Reciprocating Motion.
Radial Seals in Rotary Motion.
Inside face Seals in Static and rotary Service.
Outside face Seals in Static and rotary Service.
Section structure
Symmetric, for Rod, for Piston are available.
Spring type:
U shaped spring(Type 400)
Round wire spring (Type APS)
O shaped spring (Type 103)
Groove
Standard Heel Groove.
Extended Heel Groove
Flanged Heel Groove.
Size
Both imperial and metric sizes are available on all stype.
