Key Specifications

Product Highlights

• Pre‑assembled couplings eliminate field‑fitting errors and reduce downtime.
• Built to withstand rigorous spray or pump system environments with reliable connection integrity.
• Plug‑and‑play replacement for OEM systems simplifies maintenance and improves uptime.
• Direct fit replacement part designed to maintain original system performance and reliability.

Installation & Usage Notes

Prior to installation, ensure the system is properly depressurized and isolated. Remove the previous hose assembly and verify the mating connections are clean and undamaged. Install the new 15G784 hose by aligning the couplings to their counterparts, tighten to the manufacturer‑specified torque or clamp setting, then restore the system gradually and check for leaks, proper flow and secure connections before returning to full operation.

Maintenance & Care

• Regularly inspect the hose jacket, couplings and connection points for signs of wear, abrasion, or fluid seepage.
• Ensure hose routing remains free from sharp bends, kinks or improper support which can degrade performance.
• Replace the hose promptly if leakage, coupling damage or flow restriction is observed to preserve system safety and efficiency.
