Maximize the efficiency and hitting power of your heavy-duty breaker with the Merit Premium Seal Kit (Empaquetadura), specifically designed for the Atlas Copco / Epiroc HB 2500. In high-production environments like mining and large-scale demolition, the HB 2500 depends on its internal seals to maintain hydraulic pressure and prevent oil leaks. This kit is engineered to withstand the extreme heat and pressure spikes typical of the 2.5-ton breaker class.

Why Choose the Merit HB 2500 Seal Kit?
The HB 2500 is a high-performance hammer that generates massive impact energy. To keep this power consistent, the internal sealing system must be flawless. The Merit kit (3363 0946 05) provides:
1. Dynamic Pressure Resistance
The piston in an HB 2500 moves at high speeds with intense pressure cycles. Our Step Seals and Buffer Seals are manufactured from reinforced polyurethane that resists deformation and extrusion, ensuring the piston maintains maximum velocity without oil bypass.
2. Advanced Heat Management
Continuous operation in hard rock leads to high hydraulic fluid temperatures. Merit seals are made from heat-stabilized compounds that won’t harden or crack under thermal stress, preventing the “sudden leak” syndrome common with low-quality aftermarket kits.
3. Protection Against Contamination
The HB 2500 often works in dusty, abrasive environments. This kit includes heavy-duty Dust Wipers designed to scrape the piston clean on every stroke, preventing fine particles from entering the hydraulic circuit and scoring the cylinder walls.
Complete Repair Components
The 3363 0946 05 kit is a comprehensive solution containing all critical seals for a professional rebuild:
- Piston Seals: To ensure high-impact pressure.
- Gas Seals: To maintain nitrogen pressure in the back head.
- O-Rings & Back-up Rings: For the valve body and housing connections.
- Wiper Seals: To protect the internal system from external debris.
Key Benefits
- OEM Standard: 100% compatible with Atlas Copco / Epiroc specifications.
- Reduced Downtime: Durable materials extend the interval between maintenance cycles.
- Environmental Protection: High-integrity sealing prevents oil seepage into the ground.
Maintenance Tip: When installing the HB 2500 Empaquetadura, ensure the workplace is clinically clean. A single grain of sand introduced during the seal change can damage the new seals and the cylinder bore. Always use a generous amount of clean hydraulic oil to lubricate the seals during assembly.
