The Tru-Flate Design Plug is recognized by the extremely short pilot; however, it has the widest metal section between the groove and the pilot. The sealing surfface on the end of th eplug is wider than other interchanges, resulting in better sealing and longer seal life. The Tru-Flate Desgin Coupler utilizes the tubular valve which supports the seal and allows more air flow at lower pressure drops than most competitive couplers. The protective collar guards against accidental disconnect. Bulk. 100/box.
