Shurflo 183-029-18 Pressure Reducing City Water Entry Fitting, Wall Mount, White

The Shurflo 183-029-18 is a wall-mount pressure reducing city water entry fitting designed to connect an RV or marine fresh water system to a shore-side or dockside water supply. It steps down incoming municipal water pressure before it reaches the onboard plumbing, helping protect fittings, hoses, and fixtures from pressure spikes common on city water hookups. The housing is molded from durable plastic in a white gel finish, so it blends cleanly with most exterior wall panels and does not require painting or additional finishing.

Connection is made through a 3/4 inch GHT (garden hose thread) adapter fitting, the standard thread size used for city water and garden hose connections, making it straightforward to attach a standard water hookup hose. The unit is compact, measuring 4 x 5.25 x 5.75 inches, and mounts directly to an exterior wall for a permanent, flush-style water inlet. At 0.66 pounds, it is lightweight enough for straightforward wall installation without added structural support.
