The Honda 78312-954-010 Hose Clamp Ring is a genuine OEM component designed for the WA20 water pump. As a factory-original part, it is manufactured to the same specifications as the ring installed at the factory, ensuring a proper, consistent seal on the hose connections it secures. If your existing clamp ring has become deformed, cracked, or is no longer holding tension, this replacement restores the integrity of the hose fitting on your WA20.
Key Features
- Genuine OEM Retention — factory-original construction ensures the ring maintains the clamping tension needed to keep hose connections from slipping or weeping under pump pressure
- Exact Replacement — an OEM part sourced directly from Honda, part number 78312-954-010 matches the original component in the WA20 water pump without requiring modification
- Check Your Serial Number — Honda updates parts at production breaks, so verify your WA20 serial number against the fitment table before ordering to confirm this ring is correct for your unit
A hose clamp ring secures the suction or discharge hose connections on the water pump, preventing the hose from backing off the fitting during operation. On a pump like the WA20, a failed or weakened clamp ring can allow hose movement at the coupling point, leading to air ingestion on the suction side or fluid loss on the discharge side — either of which will reduce pump output and can cause the pump to lose prime. Replacing a worn ring promptly keeps the pump's flow path intact and the connections sealed under working pressure.
