Back up ring AM 115x125x1,7

The AM back-up ring 115x125x1.7 mm is designed to prevent extrusion and damage of O-Rings, especially in applications with large gaps or high pressure. Its uncut design reduces the risk of damaging the O-Ring under pressure. Thanks to the elasticity of TPE material, the ring can be installed quickly and without tools. It is commonly used in hydraulic and pneumatic systems where abrasion resistance and tear strength are essential.

Installation guidelines:

• One back-up ring on the opposite side for one-sided pressure

• Two back-up rings for pressure on both sides
