20-PIECE 1/4 IN NPT COUPLER AND PLUG PACK

This 20 piece set is perfect for any garage that uses multiple tools and air lines.. The couplers are constructed of brass while the plugs are made of heavy-duty steel with corrosion resistant zinc plating. The coupler's slide operates smoothly and the knurled texture provides a secure grip. A wider inner diameter delivers more air to pneumatic tools. The hex shaped body can be easily tightened with a 11/16" wrench and the threaded end fits 1/4" NPT threaded fittings. The plugs have a hex section that fits a 14mm wrench and have 1/4" male NPT threads.
