Jabsco 90° Port Flush Water Pressure Regulator — 45 PSI, White
A clean, low-profile way to protect your onboard freshwater system from shore water pressure. The Jabsco 44412-1045 mounts flush against the hull or bulkhead with a 90° port orientation — ideal when your hose connection needs to exit at a right angle to the mounting surface rather than straight through. It limits incoming city water pressure to a safe 45 PSI, keeping your pumps, hoses, and fittings well within their operating range. Food-grade materials make it safe for potable water, and the removable strainer catches debris before it reaches your system.
Key Features
- Limits incoming shore water pressure to 45 PSI — protects pumps, hoses, and fittings from high-pressure damage
- 90° port orientation — hose exits at a right angle to the mounting surface for tight-space installations
- Flush-mount design for a clean, low-profile fit against hull or bulkhead
- White finish — blends with white hulls and deck hardware
- Removable strainer catches debris before it enters the water system
- 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
- Installations where a 90° hose exit is required due to space or routing constraints
- Potable freshwater systems requiring food-grade, pressure-regulated inlet fittings
- White hull or deck installations where finish matching matters
Parts Desk Insights
The 90° port orientation is the key differentiator here — choose this model when your hose needs to run parallel to the hull surface rather than straight out from the fitting. The removable strainer is a bonus that the straight flush-mount version doesn’t include, making this a slightly more complete solution for installations where debris in the shore water supply is a concern. For a chrome finish in the same 90° port style, see the Jabsco 44412-2045 Chrome 90° Port Flush Pressure Regulator. If you need a straight-through flush-mount in chrome, the Jabsco 44412-2045 Chrome Flush-Mount Pressure Regulator is the option. Running a SHURflo pump system? The SHURflo 65 PSI Wall-Mount Pressure Regulator is an alternative at a higher pressure rating.
