MINI PRESSURE REGULATOR FOR COMPRESSED AIR SYSTEMS, 1/4" NPT PORTS, ADJUST 7 TO 140 PSI

I have ordered and used two of these for controlling air to pneumatic cylinders. While I have not used them very much, they work well and the big selling point was that the bracket and nut was included, so they can be easily mounted. Most regulators don't have the nuts or brackets available and have no way to mount them. The second nut is to lock the air adjustment. For my use, they will get adjusted, locked, and then likely won't need adjusted again since they will be mounted to machines. If you wanted to adjust it often and be able to lock it, the push or pull to lock style would be better. For the price, these do exactly what I wanted. They are small, have clear and easy to read gauges, and can be mounted, not to mention a good price.

Was only able to get it to regulate between 85 down to 80 PSI. Non functional. AMENDED... Works great. I did not see the directional arrow even though I looked for it. It is embossed in the body and when mine was painted it filled in the arrow a little. So I hooked it up backwards. Me Bad.... LOL... After geting the direction right it worked perfectly. As a matter of fact for a mini which is what I have experience with it was very accurate and responsive. Kudos to whoever made this unit.

For the price is good, not great by good. Has held up so far.

These little regulators are nice to have. I installed them on each of my nail guns so I could set the pressure on a particular gun without changing the pressure on the air for the whole shop. It's very convenient. I have bought mini regulators twice before from other manufacturers only to throw them in the trash because they didn't work. These are going strong after several months, though.

So far it’s working good, but I only used it several times. It keeps the regulated pressure it’s set at. Made much better than the original.

worked perfect but started leaking from under the adjustment knob within a day

Love the regulator - - well made, controls pressure great. The only problem was the difficulty determining the air flow direction, as it's not well marked. See the pic I posted. Gauge has a ridiculously thin case, and the needle will seize until you straighten the case back out. They packed a 5-star reg with a 1-star gauge, and either should have supplied a better one or let you supply your own. I replaced mine with "Winters PFQ Series Stainless Steel 304 Dual Scale Liquid Filled Pressure Gauge with Brass Internals, 0-160 psi/kpa 1-1/2" Dial Display, +/-2.5% Accuracy, 1/8" NPT Back Mount" (available from Amazon); now I have a high-quality setup.

Used this to replace a broken regulator on an air compressor. This one was not the cheapest, but is almost identical to the original manufacturer part (Coleman). 5 minutes to install, works fine. Pay close attention to the flow direction, it matters, and is marked on the unit. This one is left to right when looking at the pressure dial.
