Well built and works awesome. I have a 2 stage Craftsman pro 25 gallon upright compressor and moisture has been an issue. I installed the craftsman in line water separator and still problems. I have the w.s. installed low and a 50 ft. 3/8 I.D. hose between it and compressor now and problem solved. The mounting is meant to be in line on metal pipe so there is no mounting hardware. Who cares of it works well.
