  • Limits city water pressure to 50 PSI

In-line 50 PSI pressure regulator

This SHURflo in-line water pressure regulator limits city water pressure to 50 PSI and includes a built-in check valve. It is designed for users who need continuous protection from high-pressure surges at a standard hose connection. The compact unit installs easily without permanent mounting. It suits RV, marine or seasonal outdoor setups where temporary hook-ups are common.

50 PSI limit and check valve

The regulator caps incoming pressure at 50 PSI, preventing damage to downstream plumbing and fixtures. It handles normal municipal supply spikes but will not boost pressure if the source falls below the set point. The internal diaphragm and check valve meet or surpass code requirements for back-flow prevention. There is no adjustment mechanism; the factory setting is fixed.

3/4 inch GSH inlet and 1/2 inch NPSM outlet

A 3/4 inch GSH female swivel inlet threads onto standard garden-hose fittings for tool-free connection. The 1/2 inch NPSM male outlet feeds the downstream system. Hose mounting means the unit can be moved between locations without permanent installation. Cream-coloured body identifies the model at a glance.

Questions about this item

Will the 50 PSI regulator protect my existing 3/4" hose fittings from city water pressure surges?

Yes, the diaphragm design limits incoming pressure to 50 PSI and the built-in check valve stops backflow, giving continuous protection for standard 3/4" hose connections.

How can I confirm the 1/2" NPSM male outlet is delivering a steady 50 PSI after installation?

Attach a pressure gauge to the outlet side; a stable reading at or below 50 PSI while water flows shows the regulator is working as intended.

Does the package include any adapters for the 3/4" GSH female swivel inlet or the 1/2" NPSM male outlet?

The unit ships with the regulator body and integrated check valve only; any extra hose adapters or fittings must be purchased separately.
