65 PSI is on the high pressure end.
Sureflo sells an "inline" (has male and female hose connections) unit that is IDENTICAL to the installed regulator with the following changes
Take an "installed" model. remove the "Bib" (Mounting flange) add a male hose adapter to the outlet. It is literally screwed on to the outlet end Identical "Works"
I would recommend a WATTS or ZURIN in-line. these are designed to be put in line in a house with pipe fittings not hose fittings but a 3/4 (or 1/2) inch unit works great with hose adapters applied.. They are Brass not plastic so don't freeze them.. They are REBUILD-ABLE but so is the Sureflo what I don't know is if you can get kits for the sure-flo The Watts and Zurin units are very much alike in design with a bell shapped "Upper" housing the mounting bolt of the "Bell" is the pressure adjustement and a brass Lower body The spring is in the bell. I tested mine by using the shower.. Set the pressure to 50 PSI static and opened the shower valve.. SureFlo dropped slightly.. ZURIN the needle did not even wiggle.
