The MSB MS Series Hydraulic Breaker Diaphragm is a critical rubber component designed for the MSB MS Series hydraulic breakers. Also known as a nitrogen chamber membrane, accumulator diaphragm, or rubber cup, the diaphragm plays an important role in maintaining nitrogen gas pressure, absorbing vibration, and ensuring stable impact performance during hydraulic breaker operation.

The diaphragm works inside the nitrogen chamber and is exposed to repeated pressure changes, vibration, and mechanical stress. A high-performance diaphragm helps maintain nitrogen sealing, reduce pressure loss, and improve the energy efficiency of the hydraulic breaker.

Our MSB MS Series Hydraulic Breaker Diaphragm is manufactured from high-elasticity rubber materials with excellent flexibility, wear resistance, impact absorption, and fatigue durability. The optimized rubber formulation provides stable deformation recovery and long service life under high-frequency working conditions.

Produced according to OEM-compatible specifications, our replacement diaphragms provide a reliable solution for hydraulic breaker maintenance, repair, and rebuilding. They are widely used by hydraulic breaker distributors, repair workshops, contractors, and equipment owners worldwide.
