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 Fitting — Union fittings separate into three pieces so you can access your line without unthreading pipe connections.
