PTFE backup rings for greater usability

The PTFE backup rings as the name suggest are back ups to prevent extrusion in rubber o-ring sealing systems. It is a common phenomenon for rubber o-rings to extrude especially with present day fluid systems that are a combination of high pressures and high temperatures. And this is a situation where the PTFE backup ringsplaya significant role in preventing o-ring extrusion.
We, here at Valleyseal have a stockpile of these products, essentially of all the standard configurations. And we also offer our valued clientele a host of customized PTFE backup rings, whenever and wherever required.
Our back-up rings have been used extensively in high pressure hydraulic and pneumatic systems as anti-extrusion devices in conjunction with rubber O-rings in many industry sectors. We have the following products in our three PTFE backup rings range:

Standard configuration PTFE backup rings

  • Single turn (scarf cut)
  • Multi-turn (spiral cut)
