Restore the striking power and hydraulic integrity of your MTB 365 with the Merit Premium Seal Kit. The MTB 365 is a high-frequency hydraulic breaker that relies on perfect pressure retention to deliver consistent impact energy. This professional-grade kit is specifically engineered to stop external oil leaks and prevent internal pressure bypass, ensuring your breaker hits with maximum force on every stroke.

Why Choose the Merit Seal Kit for MTB 365?
The MTB 365 operates at high speeds, which generates significant heat and friction. Standard seals often harden or crack under these conditions. The Merit kit is built to survive:
1. Advanced Piston Seals
Our main piston seals are manufactured from reinforced M-Polyurethane. This material has a high “elastic memory,” meaning it maintains a tight seal against the piston even after millions of cycles. This prevents the “lazy” hitting caused by oil leaking past the piston.
2. Nitrogen Gas Retention
The efficiency of an MTB breaker depends on its nitrogen charge. Our kit includes specialized Gas Seals for the back head that are engineered to be impermeable, reducing gas loss and preventing nitrogen from contaminating your excavator’s hydraulic oil.
3. Heavy-Duty Dust Wipers
Demolition sites are filled with abrasive dust. The Merit kit features high-tensile Dust Wipers that effectively scrape the piston clean on every return stroke, protecting your internal cylinder and seal carrier from scoring and scratches.
What’s Included in the MTB 365 Kit?
This is a complete service solution for a professional rebuild:
- Step Seals & Buffer Seals: To manage high-pressure dynamic loads.
- Rod Wipers: To exclude dirt and debris.
- Back Head Gas Seals: To maintain the nitrogen charge.
- Static O-Rings & Back-up Rings: For the valve body and housing interfaces.
- Check Valve Seals: To ensure correct oil flow regulation.
Maintenance Tip: When to Reseal Your MTB 365?
Preventative maintenance is significantly cheaper than a full hammer overhaul. Replace your seals if you notice:
- Oil on the Tool: If hydraulic oil is dripping down the chisel, the lower seals are compromised.
- Loss of Impact: If the hammer is striking slower or feels “soft,” internal pressure is bypassing the seals.
- Aerated Oil: If your hydraulic oil appears foamy, nitrogen is likely leaking past the gas seals into the oil circuit.
- Annual Service: For professional operators, we recommend a full seal replacement every 600–800 operating hours.
