A worn or damaged washer is one of the more common causes of a leak at a joint on a Rinnai continuous flow water heater. This genuine P50IVR-818 washer is made to Rinnai's original specification for the HD50 and compatible VR-series units, restoring a secure seal between connected components so the joint holds pressure properly and stops leaking.
Washers and seals are a routine wear item on any appliance exposed to heat, pressure, and repeated servicing, so it's worth checking their condition during scheduled maintenance rather than waiting for a leak to appear. Fitting the genuine part keeps the joint sealed to the same standard as when the unit left the factory.
