Static Seals
Back-up ring
Additional protection element (without sealing function) to prevent gap extrusion with sealing components. To be used for pressures above 5 MPa.
Back-up ring BC - concave slotted
The Back-up ring BC has a slotted profile with a concave groove. Due to its assembly ease, it is particularly suitable for closed grooves or for all installations.It has a very good O-ring support at very high und pulsating pressures through the concave design.
Back-up rings are exactly adapted to the groove height and are turned with standard PTFE virgin material. The required groove width increases by the width of the Back-up rings.
