Precision molded rubber diaphragm for Epiroc COP1838+ and COP1838HD series hydraulic rock drill drifters. Manufactured from high-grade NBR rubber compound, this diaphragm separates hydraulic chambers, regulates pressure fluctuation and ensures reliable drifter performance in demanding mining and tunneling applications.
The 3115192602 Diaphragm is a precision molded rubber component installed inside the hydraulic valve and accumulator assembly of Epiroc COP1838+ and COP1838HD hydraulic rock drill drifters. It separates hydraulic oil chambers, regulates pressure fluctuation and prevents oil cross-flow between circuits, ensuring stable and precise operation of the drifter hydraulic system. Precision molded from high-grade NBR rubber compound with exact OEM profile, the diaphragm maintains reliable sealing and pressure response under high working hydraulic pressure, continuous percussion vibration and abrasive working conditions, effectively extending the service life of the drifter valve system.
