Why Use the Merit 3363 0872 86 Filling Kit?
The nitrogen chamber (back head) of an Epiroc breaker acts as a pneumatic spring. If the pressure is too low, the breaker loses impact energy; if it is too high, it can damage internal components. The Merit kit ensures you have total control over this balance.
1. High-Precision Pressure Monitoring
The kit features a high-quality, vibration-resistant pressure gauge. This allows for dead-accurate readings of the internal nitrogen levels, ensuring you match the exact PSI/Bar specifications required by your specific Epiroc model.
2. Robust and Leak-Free Connections
Equipped with heavy-duty brass fittings and a reinforced high-pressure charging hose, the 3363 0872 86 kit guarantees a secure connection to the breaker’s gas valve. This prevents accidental gas loss during the charging process and ensures operator safety.
3. Universal Epiroc Compatibility
This kit is designed to work across a wide range of the Epiroc/Atlas Copco lineup, making it an indispensable tool for service teams managing diverse fleets of hydraulic hammers.
Key Benefits
- Optimized Performance: Restores factory-standard striking power to your breaker.
- Ease of Use: Simple, intuitive design allows for quick on-site gas pressure checks and top-offs.
- Portable Protection: Comes in a professional-grade hard case to protect the gauge and hoses from the rough conditions of a job site.
Maintenance Guide: When to Check Gas?
We recommend using the Merit Nitrogen Filling Kit to check your breaker:
- Weekly: During periods of heavy, continuous use.
- After Storage: Always check pressure before returning a breaker to service after long idle periods.
- Performance Drop: If you notice a change in the “rhythm” or power of the hammer strikes.
Safety Warning: Nitrogen gas is under high pressure. Always follow the safety procedures outlined in your Epiroc/Atlas Copco operator’s manual when using the 3363 0872 86 kit.
