Back-up Ring BC – concave slotted
The Back-up Ring BE has a closed profile with a concave groove. Due to its assembly ease and elasticity, it is particularly suitable 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. The required groove width increases by the width of the Back-up Rings. BE Back-up Rings are produced per injection moulding. Standard materials are NBR and FKM, other compounds are available upon request.
