I purchased a 40lb blast cabinet from HF and needed a water separator tied in at point-of-use. I went to the local home store and grabbed a few 1/4" gas line elbows and a few short straights to get this lower then the door. It works great with my 5gal portable Rigid air compressor. Zero leaks at 140 PSI and removes a lot of water. I used Teflon tape on all connections of course.
Quality seems nice. Nothing bad to say about this product. My blaster works great after adding this.
Much better water removal then the $5 straight line ones you find at home improvement stores. This won't replace a nice high end filter/separator combo but for point of use and the price, not found better.
