Product Questions & Answers

does this thing work with standard industrial interchange fittings or do I need to buy a specific brand of plug to go with it?

Pretty much any male half that meets the MIL-C-4109 dimensional standard will mate up with this coupling. That covers a wide range of industrial brands, so you're not locked into one manufacturer's plugs. The Aeroquip FD40 Series and FD41 Series are confirmed compatible, along with Tru-Flate and Parker automotive-style male halves. If the plug you're running meets MIL-C-4109, you're in good shape.
