The Honda 78139-YF3-702 Hose Band is a genuine OEM component designed for WN20 and WN30 water pumps. As a direct Honda OEM part, it is manufactured to the exact specifications called out in Honda's own parts catalogue, ensuring a secure, correct-fitting installation. Verify your pump's serial number against the fitment table to confirm this is the right band for your unit before ordering.
Key Features
- Genuine Honda OEM Part — sourced directly from Honda, this hose band matches the original specification for WN20 and WN30 water pumps, with no guesswork about fitment or compatibility.
- Secure Hose Retention — a properly functioning hose band keeps hose connections sealed under pump operating pressure; a failed or missing band can allow a hose to slip or leak, disrupting flow and potentially damaging the pump.
- Serial Number Verification Recommended — Honda updates parts at production breaks, so confirm your pump's serial number against the fitment table to ensure part number 78139-YF3-702 is correct for your specific unit.
A hose band clamps a flexible hose firmly onto its fitting or port, maintaining a leak-free connection in a water pump's intake or discharge circuit. On WN-series pumps, a secure hose connection is essential for maintaining prime and sustaining consistent water flow. When a hose band corrodes, loses tension, or breaks, the hose can work loose under pressure, causing leaks or a loss of prime that brings pumping to a halt.
