Servicing Enerpac hydraulic cylinders? The Enerpac B1135564 Back-up is the genuine replacement part. The backup ring supports an O-ring or seal under high pressure so it cannot be squeezed into the gap between parts. Without a sound backup ring, the seal it protects can extrude and fail early.
When to replace the B1135564
Replace it together with the seal it supports, whenever that seal is replaced.
