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

Works great. Leaks if mounted backwards. Much more durable then other one the sticker that wears off.

Works good,accurate reading only bad thing is there is no way to lock it onto the pressure you want so you must be careful because it will move easily

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

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.

I am happy with the quality for price.

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.

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.
