🌐 Global Continuous Spare Parts Supply: Direct Delivery to Your Desired Destination.
MERIT keeps your production lines running with an agile, high-velocity distribution network designed to eliminate equipment downtime. We deliver premium-grade hydraulic breaker parts directly to mine sites, fleet workshops, and regional equipment distributors across our primary international logistical corridors:
- Latin American Copper & Gold Belt: Full regional supply of climate-resilient sealing and high-wear structural steel components across the Andean mountain ranges—with regular, prioritized dispatch handling straight to Chile (Antofagasta, Calama, Santiago) and Peru (Arequipa, Lima), as well as onwards to the ever-growing destinations added to our portfolio daily.
- Sub-Saharan Mineral Corridor: Direct supply pipelines serving primary mining sites, limestone quarries, and massive civil engineering infrastructure projects across South Africa (Johannesburg, Rustenburg), Ghana (Kumasi), and Zambia (Kitwe).
- Southeast Asian Archipelago Network: Rapid transit solutions directly serving high-volume nickel, coal, and infrastructure projects across Indonesia (Jakarta, Surabaya, Balikpapan) and the Philippines.
- Global Heavy Hubs (Europe, Oceania, The Americas): Our borderless shipping operations reach major plant hire fleets and tier-one mining projects from Frankfurt to Perth, Houston to Zagreb, and onwards straight to your job site. Wherever your hammer operates, MERIT guarantees direct factory-to-door delivery.
High-Pressure Fluid Containment Matrix for 32-to-50-Ton Carrier Excavators
The Hydraulic Breaker Seal Kit (widely referenced as the Juego de Juntas, Cylinder Packing Set, or Overhaul Seals) is the critical fluid-containment and pressure-isolation matrix custom-compounded for the high-tonnage Caterpillar H160, H160D, and H160E heavy-range hydraulic rock breakers. Tasked with managing severe hydraulic operating pressure variations (160 to 180 bar) inside a massive 3-ton hammer assembly, this premium sealing group acts as a high-performance equivalent engineered to eliminate internal fluid loss.
Positioned across the main distributor valve block, high-pressure accumulator mounting faces, and the central reciprocating piston cylinder sleeve, these seals prevent critical oil bypass. This ensures that 100% of the carrier excavator’s oil flow is efficiently directed into driving the striking piston, maximizing impact velocity in hard limestone, concrete demolition, and infrastructure trenching.
MERIT manufactures this elite replacement seal group using a multi-material configuration engineered to withstand sustained operational oil temperatures up to 110°C and intense continuous friction cycles without cracking, hardening, or tearing.
Technical Features and Material Engineering of MERIT H160 Sealing Kits
Surviving continuous exposure to intense high-frequency hydraulic shockwaves and preventing external oil leaks in demanding heavy-quarry environments requires absolute chemical and dimensional precision. MERIT ensures field reliability through:
1. Bronze-Filled PTFE Dynamic Step Seals
The primary dynamic piston rod seals are composed of premium PTFE (Teflon) filled with Bronze paired with high-elasticity Fluorocarbon (FKM/Viton) square energy expanders. This advanced engineering design limits stick-slip friction on the reciprocating piston shank, eliminating cold scuffing while maintaining an absolute fluid barrier under high pressures.
2. Heavy-Duty Polyurethane (PU) U-Cups & Wipers
Our specialized dual-lip polyurethane dust wipers and rod seals form a strict protective barrier at the front head tool interface. They aggressively reject abrasive rock dust, concrete slurry, and environmental moisture ingress while securely containing the internal oil circuit to eliminate high-pressure blow-by.
3. High-Durometer Anti-Extrusion O-Rings
Static sealing surfaces utilize 90 Shore A hardness Nitrile (NBR) O-rings reinforced with contoured thermoplastic back-up rings. This multi-layered defense prevents seal extrusion, flattening, or clipping across structural block gaps, valve housings, and main pressure points during intense hydraulic rebound peaks.
Primary Overhaul & Maintenance Applications
- Complete Power Cell Rebuilds: Restoring factory-standard pressure isolation during comprehensive mid-life hammer servicing and cylinder refurnishing.
- Preventative Leak Mitigation: Replacing degraded, heat-hardened elastomer groups before external fluid loss causes excessive oil consumption or environmental site contamination.
- Volumetric Efficiency Restoration: Swapping worn dynamic rings to correct low impact frequency, tool drifting, or sudden drops in rock-breaking velocity.
