FKM PU Rubber Hydraulic Breaker Seal Kits For CAT H Hammer
Mine-Grade FKM PU Seal Kits For CAT H Breaker Block Oil Extrusion And Maintain Stable Breaking Impact Output
CAT H series hydraulic breaker full overhaul seal kits are integrated maintenance sealing accessories matching small, medium and heavy-duty CAT H hydraulic breakers H160 to H410. The complete set covers all sealing positions of piston, front guide bushing and rear nitrogen accumulator, widely used in mini-excavator garden renovation, urban concrete demolition and large open-pit hard rock mining projects.
The product mixes multiple high-performance elastic materials to adapt harsh high-load working environments. FKM Viton material boasts excellent hydraulic oil and high temperature resistance for uninterrupted all-day operation; high-toughness PU buffer seals absorb instantaneous recoil impact to avoid tearing deformation; built-in PTFE back-up rings effectively prevent seal extrusion damage under peak hydraulic pressure.
Precision mold forming follows strict OEM dimensional standards for direct replacement without secondary trimming. Complete matched sealing accessories fully eliminate pressure loss and oil leakage, stabilize continuous striking performance and reduce eccentric wear of metal wearing parts such as piston, inner & outer bushings and through bolts.
Every batch of seal kits undergoes hydraulic tightness test, high-temperature oil aging inspection and reciprocating friction fatigue calibration to meet original equipment interchange standards. Full specification ready stock supports single-piece maintenance orders and large bulk wholesale for construction contractors and mine equipment rental yards. Custom rubber hardness, seal combination and anti-oil aging formula customization are available for global machinery maintenance factories and spare parts dealers.
