Backup Ring 1-11680-240 KMT Waterjet Parts Supplier

The Backup Ring 1-11680-240 is a precision-engineered seal support component designed to prevent O-ring extrusion and deformation in high-pressure waterjet and hydraulic applications. It reinforces sealing integrity under extreme pressure and temperature variations, ensuring reliable, leak-free performance and extended seal life.

Manufactured from high-strength PTFE or filled polymer materials, the 1-11680-240 backup ring offers exceptional wear resistance, chemical compatibility, and dimensional stability. Its smooth, low-friction surface allows the O-ring to maintain proper compression while resisting extrusion into hardware gaps during pressure spikes.

This KUNDA backup ring is commonly installed alongside U-cup seals, O-rings, and static sealing elements in waterjet intensifiers, Hydraulic Pumps, and high-pressure manifolds. Engineered to meet OEM specifications, it provides consistent support and durability in both dynamic and static sealing environments.
