Jabsco In-Line Water Pressure Regulator 45psi - White

The Jabsco In-Line Water Pressure Regulator 45psi in white is a marine-duty regulator engineered to protect your vessel's freshwater plumbing system from excessive city water pressure when connected to dock-side sources or campground faucets. Whether you're a weekend cruiser or run extended offshore trips, unregulated water pressure from shore connections can damage seals, rupture lines, and create costly leaks. This Jabsco regulator maintains consistent output pressure across low and high flow rates, keeping your galley, head, and shower systems safe from pressure spikes.

The 45psi preset pressure setting is optimized for typical dock and RV pedestal connections, where pressures often exceed 80psi. A removable strainer cartridge intercepts pipe scale, sediment, and debris before they reach your valves and seals—reducing maintenance headaches and extending the life of downstream components. The compact white housing measures 4 x 2 x 7 inches and installs cleanly in tight engine room or galley spaces. At just 0.25 lbs, it adds negligible weight while delivering professional-grade pressure regulation.

This is the go-to choice for cruising sailors, liveaboards, and RV water system users who value system integrity and simplicity. Jabsco has been the marine original equipment standard for decades—their regulators are found in production boat systems worldwide. If you've had a water line fail or seal blow at the worst possible moment, you understand why pressure regulation matters. This regulator prevents that scenario before it starts, delivering peace of mind every time you hook up to shore water.
