Product Description
High-Performance B220-3006 Hydraulic Breaker Diaphragm for Everdigm EHB25 & RHB325
Optimize the impact frequency and energy of your Everdigm EHB25 and RHB325 hydraulic hammers with the B220-3006 premium diaphragm membrane. The diaphragm is a critical component of the accumulator, acting as a flexible barrier between the nitrogen gas and hydraulic oil. A worn or ruptured diaphragm leads to reduced hitting power and increased vibration, which can damage your excavator’s hydraulic system.
At Toparts, we provide industrial-grade diaphragms manufactured from specialized reinforced rubber compounds. Our membranes are engineered to withstand millions of cycles under extreme pressure and temperature fluctuations.
Product Highlights:
Perfect Compatibility: Precision-molded for Everdigm EHB25 and RHB325 hydraulic breakers (Part Number: B220-3006).
Advanced Rubber Compound: Made from high-resilience, fabric-reinforced material that offers superior resistance to gas permeation and hydraulic oil degradation.
Restore Impact Power: Maintains consistent nitrogen pressure in the accumulator, ensuring your hammer delivers its maximum rated energy with every stroke.
Exceptional Fatigue Life: Formulated to endure high-frequency stretching and compression without cracking or losing elasticity.
Heat Resistance: Performs reliably even during continuous operation in high-temperature environments typical of heavy-duty demolition.
