Installation requirements of PTFE coated O-ring

Jul 15, 2020

Installation requirements of PTFE coated O-ring:

   1. The contact surface required to be installed or passed through the sealing ring needs to be smooth, without grooves, sharp corners and burrs, the profile of the inner hole must reach 20 millimeters, and the profile of the shaft should reach 10 millimeters;

   2. Use clean light oil or grease to lubricate the relevant parts of the seal ring surface and the contact surface;

   3. When it is difficult to install the sealing ring on the shaft, the sealing ring can be soaked in hot water to expand it for easy installation. And after the sealing ring is thermally expanded and installed, it can be restored to its original size after cooling;

   4. Do not bend the O-ring too violently, otherwise it will cause the wrinkle of the coated PTFE and affect the normal use.
