A tight seal at the fresh water fill point matters - nobody wants water leaking into a wet bay instead of the tank. This Valterra fitting uses an O-ring seal to close up snugly, and its ABS body is built to handle regular use at the fill station or campground spigot.
It's sized to work with either a 0.375-inch or 0.25-inch tank inlet hose, so it covers two common hose sizes with one part, and the ivory finish matches typical RV exterior panels.
A simple, inexpensive part worth keeping on hand if your current fill fitting is cracked or the seal has gone stiff with age.
