The MSB MS Series Hydraulic Breaker Seal Kit is a complete sealing solution designed for MSB MS Series hydraulic breakers. As essential maintenance components inside the hydraulic hammer, the seal kit helps prevent hydraulic oil leakage, maintain stable internal pressure, and ensure smooth piston operation during continuous impact work.

Hydraulic breakers operate under high pressure, repeated impact loads, friction, and temperature changes. The sealing system plays a critical role in maintaining the efficiency and reliability of the breaker. When seals become worn or damaged, problems such as hydraulic oil leakage, reduced impact force, unstable operation, and accelerated wear of internal components may occur.

Our MSB MS Series Hydraulic Breaker Oil Seal Kit includes various sealing components such as piston seals, main oil seals, dust seals, buffer seals, O-rings, and backup rings. Manufactured from high-performance sealing materials, these components provide excellent oil resistance, wear resistance, elasticity, and long service life.

Produced according to OEM-compatible specifications, our replacement seal kits provide a reliable solution for hydraulic breaker repair, maintenance, and rebuilding. They are widely used by hydraulic breaker distributors, repair workshops, contractors, and equipment owners worldwide.
