Medium-Pressure Iron and Steel Threaded Pipe Fittings
With better strength than our low-pressure iron and steel pipe fittings, these can handle medium-pressure applications. They are for use in noncorrosive environments.
Union connectors separate into three pieces so you can access your line without unthreading pipe connections.
Female x male 90° elbow adapters are also known as street elbows.
Inline tees are also known as branch tees.

Medium-Pressure Galvanized Iron and Steel Threaded Pipe Fittings
A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.
Union connectors separate into three pieces so you can access your line without unthreading pipe connections.
Female x male 90° elbow adapters are also known as street elbows.
Inline tees are also known as branch tees.
