Works nicely for filling tires to preset pressures.

I use this downstream of my onboard air to inflate tires to a chosen pressure without having to hold an inflator trigger the whole time, or risk over-inflating when attaching a hose directly between the compressor and tire. I've put a female coupling on the output, so to set it I plug in my inflator (with gauge) and dial in the pressure I want, then remove the inflator and replace it with a T, two hoses, and two Haltec H-5265 chucks to two tires. This lets me air up two tires at a time relatively unattended and make sure they all have the same end pressure after off-roading (15->50psi), plus makes it easy to bring up the pressure further in the rear two tires when needed for heavy towing (50->80psi).
I've only used it a handful of times at this point, but it's holding up well so far, including being put loose in a bag with other air-up parts and not handled particularly carefully. Since I'm using a simple onboard air system I don't have an air filter and dryer upstream of this regulator, so I don't know how long it will last before the lack of filtering causes any problems, but no issues yet.
