Valterra RV City-Water Inlets: MPT vs FPT & Mounting
Valterra city-water inlets connect a pressurized campground hose to an RV's water system. A replacement needs the correct outside flange and the correct rear pipe thread. The half-inch MPT versions have a male-threaded plumbing end, while FPT versions have female threads. Recessed and flush mounting also affect how the inlet sits on the exterior wall.
Flush inlets
A 2-3/4-inch exterior flange fits over the inlet mounting area. In this group, 0169LF and 0170LF have 1/2-inch male pipe threads; 0171LF and 0172LF have female threads.
Recessed inlets
Valterra 0176LF and 0177LF use a recessed flange with 1/2-inch female pipe threads. They differ in white versus Colonial White finish; confirm the cavity depth and original mounting layout.

Rear-thread difference: MPT means male pipe thread; FPT means female pipe thread. All models shown are city-water inlets, not gravity tank-fill hatches. Match the existing connection and wall mounting before ordering.
Five checks for a city-water inlet replacement
- Identify the rear fitting as male pipe thread (MPT) or female pipe thread (FPT). Two 1/2-inch fittings are not interchangeable merely because their nominal size is equal.
- Determine whether the existing inlet is flush or recessed, and measure the flange diameter, recess depth and mounting-screw pattern.
- Check the garden-hose swivel, dust plug and brass check valve for leaks or damage. A replacement inlet should not be used to conceal cracked RV piping.
- Choose the correct exterior finish and confirm the mating pipe fitting type before applying appropriate potable-water-compatible thread sealing.
- Follow the RV plumbing manufacturer's pressure limitations and leak-test instructions. A city-water inlet does not fill a gravity tank unless the RV's plumbing is designed to do so.
