Product Description
Premium Mining-Grade 3363122470 Hydraulic Hammer Service Repair Kit for Epiroc HB2500
Restore the relentless striking power and zero-leakage performance of your heavy attachment with Toparts' premium 3363122470 hydraulic breaker seal kit. Precision-engineered for the Epiroc HB2500 heavy-duty rock hammer (operating on 27 to 40-ton class excavators), this overhaul service kit is custom-tailored to withstand the immense thermal loads and crushing hydraulic pressures encountered during primary rock quarrying, mining, and large-scale demolition.
The Toparts Engineering Difference: Built for Large-Scale Percussion
Large-tonnage rock breakers like the Epiroc HB2500 run at high oil temperatures and generate massive shock waves. Standard aftermarket seals degrade rapidly, resulting in nitrogen gas pressure loss or internal oil bypass that leaves your hammer sluggish. At Toparts, we manufacture our 3363122470 kits to high-performance heavy-industry standards:
Upgraded P6000 Polyurethane Matrix: Our primary dynamic rod and accumulator seals are molded from proprietary P6000 PU. This compound boasts 45% higher modulus and exceptional extrusion resistance under continuous working pressures exceeding 180 bar, preventing seal lip flattening and extrusion.
Dual-Function Gas-Oil Sealing System: Precision PTFE step seals combined with premium NBR energy rings ensure an airtight barrier for the nitrogen back-head chamber while keeping hydraulic fluid isolated, restoring the hammer's crisp factory-spec impact frequency.
Advanced High-Heat Fluid Containment: Formulated to maintain full elastic memory and continuous radial lip force at constant operating temperatures reaching 120°C, preventing the compound from brittle fracturing.
Heavy Dust Excluder Wipers: Features a rugged metal-clad double-lip wiper design that aggressively scrapes off fine rock dust, quartz sand, and external contaminants before they can scratch the main piston or contaminate the hydraulic line.
