Product Description

PTFE packing is a good sealing material, and it is made by braiding PTFE strips.
With High cross-sectional density and structural strength ;
Low coefficient of friction result in easy shaft running ;
Long lubricant squeezed out under operating pressure.

Application:
PTFE packing is for dynamic seal at high linear speed, often used in check and needle valve stems, reciprocating rods, rams, and plungers, and safety injection system valves.

Specifications:
1) Pressure: 2MPa in centrifugal pumps, 10MPa in piston pumps, 20MPa in valves
