Technical Specifications

Why Use a Back-Up Ring?

In high-pressure systems, O-rings alone can deform or extrude, leading to leaks and premature failure. The Graco 0137-016 Back-Up Ring reinforces the seal, ensuring stability and extending the life of the sealing system. It is an essential component for maintaining performance in professional spraying and fluid handling equipment.
