Product Introduction
N518 PTFE Spring Energized Seal is a spring- energized, pressure-assisted sealing device consisting of a PTFE (or other glass) seal partially encapsulating a corrosion-resistant metal spring energizer.
The PTFE jackets are precisely machined, filled with PTFE composites and other high performance glass, 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.
Section Structure
For Symmetric, for Rod, for Piston are available.
Material
Virgin PTFE, PTFE filled
Colour
blue,black,brown,white,green
Spring Style
U shaped spring(Type 400)
Round wire spring (Type APS)
O shaped spring (Type 103)
Groove
Standard Heel Groove.
