This product worked as expected and was easy to install. It solved a long standing problem of water hammer in the refrigerator ice maker

We are glad to know our RO system will not explode if there is a spike in the water pressure. Very easy to install with push fit connectors. No problems with leaks and fit perfectly with our 1/4" tubing. Great quality and value for the money.

A solid device, used to reduce pressure for my robot vacuum water supply.

Put the 40psi version on our refrigerator's ice maker line. Fridge no longer squeals like it's dying a painful death. Press connect is the way to go. No leaks on a 1/4" O.D. copper line.

My DuPont housing for my charcoal water filter started to leak at the Red Button air bleed. The housing is only rated for 70 psi and my city water supply is 70-75 psi. This lowered my pressure to 42 psi. This worked as it was supposed to in lowering the pressure. (Should have done this at the original install.)

Sometimes you get what you pay for. Reduced flow, incorrect pressure. The flow rate was almost not usable. Not worth my time to return. Found another Pressure Regulator for my RO system (on Amazon) and it works perfectly for only a couple bucks more. Skip this one.
