Back-ups
Back-up rings are installed together with o-rings or other accompanying seals to prevent gap extrusion in sealing applications. They are available in a spiral, split, or solid design.
Commonly used with metric o-rings, these back-up rings are made of virgin PTFE unless suffix specifies otherwise.
