The Enerpac B1110566 Back up is a genuine Enerpac replacement part for Enerpac hydraulic pumps. 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 B1110566
Replace it together with the seal it supports, whenever that seal is replaced.
