Why Choose the Merit Hose Set for Your Breaker?
Hydraulic hoses are the “arteries” of your breaker. Using the 3363 0838 78 and 3363 0838 74 set provides several critical benefits:
1. Extreme Pressure Performance
Hydraulic breakers operate with rapid pressure spikes. These Merit hoses are built with high-tensile steel wire reinforcement to handle constant “flexing” and pressure surges without fatigue or hose “expansion,” which can sap hitting power.
2. Abrasion and Weather Resistance
The outer cover of these hoses is made from high-quality synthetic rubber, designed to resist ozone, sunlight, and the harsh abrasive dust found on demolition sites. This prevents the cover from cracking and exposing the steel reinforcement to rust.
3. Precision-Engineered Fittings
Part numbers 3363 0838 78 and 3363 0838 74 feature factory-crimped, heavy-duty fittings that match Epiroc/Atlas Copco OEM specifications perfectly. This ensures a leak-free connection to the breaker’s head, preventing messy oil spills and hydraulic contamination.
Key Benefits
- OEM Compatibility: Direct replacement for the original Atlas Copco/Epiroc hose lines.
- Flexibility: Optimized bend radius for easy installation within the breaker housing.
- Durability: Rated for high-temperature hydraulic fluids and heavy-duty vibration.
Maintenance Tip: When to Replace Hoses?
To prevent catastrophic failure on the job site, inspect your 3363 0838 78 / 74 hoses for:
- External Abrasion: Any signs of the wire braid being visible.
- Leakage: Oil dampness around the crimped fittings.
- Kinking: Soft spots or permanent kinks in the hose body.
Safety Note: Never attempt to “patch” a high-pressure hydraulic hose. Always replace the full set (3363 0838 78 and 3363 0838 74) to ensure balanced flow and maximum safety for the operator.
