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.
Used primarily as an anti-extrusion device for u-seals, these back-up rings combine high performance with very low friction. “ST” suffix designates a split ring.
