PTFE back-up rings, KLINGER Kempchen
Code: KAT_KEMPTFE-OPERNE_000100
Product detailed description
A PTFE back-up ring prevents the rubber O-ring from being extruded into the sealing gap between piston and cylinder during axial movement and at pressures above approx. 2.5 N/mm² (25 bar), which would destroy the O-ring.
KLINGER Kempchen (Oberhausen, Germany) is a manufacturer of industrial gaskets, packings and expansion joints of the KLINGER Group (KLINGER Kempchen catalogue).
Advantages of PTFE: chemical and thermal resistance, a PTFE film on the sliding surface of the cylinder or piston reduces O-ring friction, easy installation and removal, considerably longer O-ring service life.
