Diaphragm
Bendix

The diaphragm features precise dimensions to ensure reliable sealing and pressure distribution within hydraulic and pneumatic brake valve circuits. With width and length at 50 mm and a slim 3 mm height, this component is designed to minimize spring-back time while maintaining a tight seal under fluctuating pressures. Within the 42848 category, diaphragms of this type play a pivotal role in translating pressure differentials into controlled valve movement, contributing to accurate valve seating, response time, and overall brake feel. The VMRS code 013-010-035 situates it among other sealing elements that tolerate many service environments, including exposure to lubricants, heat, and vibration typical of heavy-duty systems. Cross-references are minimal, indicating a straightforward replacement that aligns with standard interface geometries and groove dimensions. The practical applications span idle-to-full-pressure transitions in booster and valve assemblies, where crisp actuation and leak-free performance are essential for consistent stopping power. In fleet maintenance, this diaphragm supports predictable brake response, reduces the likelihood of creeping pressure, and helps maintain compliant performance across varying operating conditions.
