McMaster 7739K178 High-Pressure Galvanized Steel Pipe Fitting Union Straight Connector, 1-1/2 NPT Female
Original price was: $106.28.$26.57Current price is: $26.57.
A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Pressure Class 3000 fittings, they have excellent strength to handle high-pressure applications.
Union connectors separate into three pieces so you can access your line without unthreading pipe connections.
