Huilian MTB120 Seal Kit – Durable Excavator Breaker Seals
The Huilian MTB120 Seal Kit is designed to keep your excavator breaker running reliably and efficiently. Built by Huilian — a professional OEM supplier since 2005 — this seal kit supplies everything needed to service the MTB120 hammer, helping prevent hydraulic leaks, restore performance, and extend service intervals.
Why choose the MTB120 Seal Kit?
- OEM-quality materials: Seals and O-rings are made from high-grade elastomers (NBR/PU variants) chosen for oil resistance, abrasion protection, and temperature stability. This means a longer service life under tough field conditions.
- Complete set: The kit includes main seals, rod seals, guide/wear rings, backup rings and O-rings — all the parts technicians typically replace during a rebuild. You get a coordinated set sized for MTB120 models to ensure proper fit and function.
- Easy maintenance: Parts are organized for quick swap-out, reducing downtime and simplifying field repairs. Clear fitment and guidance make installation straightforward for trained technicians.
- Performance and protection: Proper sealing reduces hydraulic fluid loss, prevents contamination ingress, and maintains hammer power. That protects pistons and internal components, lowering long‑term repair costs.
- Quality control and testing: Manufactured and inspected by experienced R&D and QC teams at Huilian, each kit meets strict tolerances and performance standards before shipping.
