The Honda 78139-YE5-003 Hose Band is a genuine OEM replacement designed for WP20 and WP30 water pumps. As a direct Honda OEM part, it is manufactured to the same specifications as the original component and is confirmed for use across the WP20 and WP30 pump lineup. Because Honda supersedes parts at production breaks, verify your pump's serial number against the fitment table before ordering to ensure part number 78139-YE5-003 is the correct match for your unit.
Key Features
- Genuine OEM Clamping Integrity — sourced directly from Honda, this hose band provides the same clamping force and dimensional fit as the original, keeping hose connections firmly seated under operating pressure.
- Purpose-Built for WP20 and WP30 Water Pumps — confirmed fitment for both Honda WP-series centrifugal water pumps; match your model and serial number to the fitment table before purchasing.
- Direct Drop-In Replacement — this part installs exactly like the original, with no reworking of the hose connection required.
A hose band is a clamping fastener that holds a rubber hose firmly onto its fitting or barb, preventing the connection from loosening under the vibration and internal pressure a running water pump generates. On the WP20 and WP30, hose bands secure the suction and discharge hose connections that keep water moving through the pump. When a hose band weakens, corrodes, or loses its clamping tension, the hose can work loose, causing leaks or a loss of prime that stops the pump from moving water efficiently. Replacing a worn or damaged hose band restores a tight, leak-free connection and keeps the pump operating at full capacity.
