Jabsco Flush-Mount Water Pressure Regulator — 45 PSI, Chrome
Keep your onboard freshwater system safe from the high-pressure surges that come with shore water connections. The Jabsco flush-mount pressure regulator limits incoming city water pressure to a steady 45 PSI — well within the safe operating range for marine plumbing, pumps, and fittings. The flush-mount design sits cleanly against the hull or bulkhead for a finished, low-profile installation, and the chrome finish holds up in the marine environment while looking sharp at the dock. Brass GHT fittings and food-grade materials make it a proper fit for potable water systems.
Key Features
- Limits incoming shore water pressure to 45 PSI — protects pumps, hoses, and fittings from high-pressure damage
- Flush-mount design for a clean, low-profile installation against hull or bulkhead
- Chrome finish — corrosion-resistant and polished for visible dock-side installations
- Brass GHT fittings for standard potable garden hose connections
- Manufactured from food-grade materials — safe for potable water use
- Inlet: ¾" FGHT (female garden hose thread) | Outlet: ½" NPT male
Compatible Applications
- Shore water connections on powerboats, sailboats, and liveaboards
- Marina dock connections where city water pressure exceeds safe onboard levels
- Potable freshwater systems requiring food-grade, pressure-regulated inlet fittings
- Flush-mount installations on hull sides or bulkheads
Parts Desk Insights
The flush-mount style is the cleaner installation choice when you want the regulator to sit flush against the hull or a panel rather than protruding — common on sailboats and cruisers where dock connections are permanent or semi-permanent. The 45 PSI rating is appropriate for most marine freshwater systems. If you prefer a white finish to match your hull or deck hardware, the Jabsco 44412-1045 White 90° Port Flush Pressure Regulator is a close sibling. For a chrome 90° port version, see the Jabsco 44412-2045 Chrome 90° Port Flush Pressure Regulator. If you’re running a SHURflo pump system, the SHURflo 65 PSI Wall-Mount Pressure Regulator is an alternative at a higher pressure rating.
