Adjustable in-LINE Pressure Regulator for Pneumatic Tools, 1/4" NPT, Connects Directly to AIR Tool (43-87 PSI)

After looking at reviews for this product I was a bit concerned that what I purchased would not work. I'm pleased to report that initially it has assembled well and does not leak. The markings on the barrel are a bit misleading, there is an Arrow on the blue piece which doesn't represent anything as far as I can tell. The entire blue barrel rotates and there is a white index line on the black upper portion that denotes the setting. It must be installed on a tool or the black top threads must be held in place in order for the blue barrel to rotate. I teflon taped both connectors and it does not leak, so far it works.

This product work fine, I just wish it wouldn't constantly leak air per design, but it serves it purpose.

Second unit pours out air, did not wprk straight out of the package. Garbage.

I use this regulator every day for painting it is Versatile and well made I have not ever experienced it leaking air or backing down in psi.I have recommended it to coworkers that have a need for a small easy to pack and carry regulator.

Great idea, but doesn't hold its position when you chose the higher PSI Setting.

I am happy with the quality for price.

Product does not work at all. There was not part of this regulator that turned, I even attempted to turn with some Chanel locks and it did not work. Do not buy, spend more on something else.

Works, but the way it's designed without a locking mechanism, the PSI that you set will slowly turn and cause the pressure to go down as you use the tool.
