Key Specifications

Product Highlights

• Comes with factory‑installed couplings—no need for field crimping or fitting assembly.
• Designed for professional‑grade usage: strong construction and reliable sealing.
• Plugs directly into compatible equipment to reduce installation time and error.
• Maintains system integrity by ensuring proper fit and connection quality per OEM standards.

Installation & Usage Notes

Before installation, shut down and depressurize your system. Remove the old hose assembly along with any worn or damaged connectors. Route the new hose so there are no tight bends or kinks, align the couplings correctly with the mating connections, and tighten to the correct specification. After installation, gradually restore flow and verify that there are no leaks or abnormal behavior before returning to full service.

Maintenance & Care

• Inspect regularly for signs of wear on the hose jacket, couplings and fittings.
• Ensure the couplings remain tight and there is no play or leakage at connection points.
• If leakage, kinking or coupling damage is noted, replace the hose assembly immediately to maintain safe and reliable operation.
