Forged fittings are manufactured by forging steel, which increases strength and reliability. They are available in:

Threaded (Screwed) Ends

Threads conform to NPT (National Pipe Thread) standards. No welding is required—simply screwed into place.

Socket Weld Ends

Pipes are inserted into a recessed area and welded around the joint—ideal for high-leakage integrity.

Common Types of Forged Fittings

Fitting Type Available as Use
Elbow (45°, 90°) Threaded / Socket Weld Changes direction
Tee Both Branching lines
Coupling Both Connects two pipes
Shapes Available Mostly round Round, square, rectangular
Union Threaded Allows easy disconnection
Cross Both Four-way junction
Cap Both Closes pipe ends
Plug Threaded Seals pipe openings
Bushing Threaded Reduces pipe size
Reducer Socket Weld Changes diameter of pipe

Pressure Ratings

Forged fittings are classified by pressure class:

Class 2000 – Threaded
Class 3000 – Threaded / Socket Weld
Class 6000 – Socket Weld
Class 9000 – Socket Weld (high-pressure)
