Our range of Back-up Rings:

Back-up rings PTFE

PTFE back-up rings, also known as PTFE anti-extrusion rings or support rings, are used to support and protect O-rings from gap extrusion under high pressure. Made from PTFE, these rings are ideal for applications involving high temperatures, high pressure, or aggressive media. Thanks to their shape and material, PTFE back-up rings provide an effective sealing solution for static applications in both hydraulic and pneumatic systems.
