MTB GA Series Hydraulic Breaker Seal Kits Oil Seal Repair Kit for Gas Hammer

Our MTB GA Series Hydraulic Breaker Seal Kits are complete hydraulic repair kits specially designed for MTB GA gas-type closed box hydraulic breakers. Each seal kit contains all necessary O-rings, piston seals, rod seals, dust seals, backup rings and gaskets. These sealing components prevent hydraulic oil leakage, stop dust and rock debris from entering the internal cylinder assembly, and maintain stable nitrogen pressure inside the back head during hammer operation.

All sealing parts are made of high-performance polyurethane and nitrile rubber materials. With excellent oil resistance, abrasion resistance and high temperature resistance, they can endure repeated high-frequency impact and pressure fluctuations in heavy-duty mining and demolition environments. Our seal kits help you restore the breaker’s original impact performance, eliminate internal and external oil leaks, and protect expensive core components like piston and cylinder from contamination damage.

We supply full model coverage for MTB GA series breakers: GA70, GA100, GA150, GA200, GA300, GA400. Our replacement seal kits are direct interchangeable repair parts for original MTB GA hammer, widely used on excavator-mounted hydraulic hammers for open-pit mining, rock quarrying, concrete demolition, road construction and boulder breaking. Oil leakage is the most common breaker fault; timely replacement of the whole seal kit can avoid further costly component damage.

OEM & custom service is available. We can prepare customized seal packages according to your requirements. All MTB GA breaker seal kits are supplied at competitive factory price, controllable lead time and reliable after-sales support.
