NEIKO 30253A Water and Oil Separator for Air Line | 1/4" NPT Inlet and Outlet | 150 PSI | Air Compressor and Air Tool Accessory | Protect Lifespan of Pneumatic Tools | Optimize Performance, Black

I've got this mounted to my pancake compressor. The valve is easy to clear and it gives me peace of mind that moisture stays out of my tools. I really like Neiko's quality and was happy to pay double for a metal housing like this versus the plastic harbor freight body that I had been using. It's more durable and a lot smaller so it's less in the way on a portable unit. Unlike the HF model though, this doesn't seem to be serviceable, you can't dry the media out and reuse it, as far as I can tell.

Of course do not over tighten, like all things it can be broken, but I like these over the plastic ones.

Works ok, but it does seem to function a bit better if you can get the purge to point downward when it’s screwed in. Overall seems like a good purchase so far.

Keeps the muck out of my plasma cutter well; I punch the drain button every ten minutes or so of cutting time, and moisture (and probably a little oil) clearly sprays out. Seems well-made, no issues after several hours of use.

I have two of these units installed on my two medium-duty compressors and they seem to work perfectly. At the end of the day, you push the button and whatever moisture it trapped is expelled. Simple and easy to use.

My wall mount water/oil filter was working well for normal use withthe 30 gal comperessor but didn't get everything out. I added this inline filter to my soda blaster to ensure that the material wouldn't clump up and clog the nozzle. So far I am very satisfied with this product and would consider adding it to my other air tools to prevent moisture build up on the internal components.

Got this a while back and finally got around to putting it on. I cut the 1/4" supply line a foot or so from the Compressor QR and hooked it up with hose barbs. Afterwards I turned on the air and it was leaking all over. I then took it apart and reviewed the construction to see just how deceptive this thing is. It looks nice and sturdy from the outside, compared to the clear acrylic one but really it's a chunk of steel tubing that slides over a flimsy o-ring on each end. Fortunately the ends are sturdy metal material but when under pressure the friction fit just isn't enough. I had a clear acrylic version laying around, so I put that in and got it to seal up even at 150 though it's rated for 90. I globbed on a small bit of o-ring grease, reassembled and tightened up real good, then put it back in the tool drawer. I guess I'll give it another try after the acrylic one fails.

This item product arrived very quickly and was very easy to install. The moment I opened the package, which by the way was very secured, the first thing I noticed was how solid and well made it is. So Yes I can understand why this is rated for 150psi and the price is right as well. I 100 percent recommend water and oil filter.
