About Replacement of PTFE O-ring

ORZ/1

According to the following procedure you could replace old O-ring with new one by special "Jig(ORZ/-)". Please note that PTFE is so soft that it will be made a scratch easily.

  1. Please prepare a suitable jig for size of O-ring which you want to change. For more information about jig, a tapered glass tube and a knag, please check the page of "Clip and Jig".
  2. Please insert O-ring to the tapered glass tube and push it to expand by the knag. At this time if you would push by finger, it will acquire fat and dust on the surface of O-ring.
  3. Please set up the expanded O-ring in proper position, and oven-fry or heat with a burner.
  4. Please blot the O-ring to clean up with soft cloth.
  5. It becomes as good as new.
