Precision molded rubber cup seal for Epiroc COP1638, COP1838 and COP1838HD series hydraulic rock drill drifters. Manufactured from high-grade NBR rubber compound, this sealing component prevents hydraulic oil leakage, blocks rock debris ingress and ensures reliable drifter performance in demanding mining and tunneling applications.
The 3115233300 Cup Seal is a precision molded rubber sealing component installed at the front percussion cylinder of Epiroc COP1638, COP1838 and COP1838HD hydraulic rock drill drifters. It forms a reliable sealing barrier between the percussion chamber and the front guide assembly, preventing hydraulic oil leakage while blocking abrasive rock dust and debris from entering the drifter interior. Precision molded from high-grade NBR rubber compound with exact OEM profile, the cup seal maintains stable sealing performance under high hydraulic pressure, continuous percussion vibration and abrasive working conditions, effectively extending the service life of the drifter front end.
