The Seal 86679388 is a critical barrier against hydraulic oil leakage and dust intrusion in HC25 Hydraulic Rock Drills. Generic nitrile rubber seals often harden and fail within 500-600 hours, leading to average monthly oil loss of 3-5 liters. This OEM seal is formulated with anti-aging additives, enabling it to withstand temperatures from -30℃ to 120℃ while maintaining elasticity. Its precision fit (±0.003mm tolerance) with HC25 interfaces ensures zero leakage throughout the 800-hour service life.
