Threaded Stainless Steel Pipe Fittings

Threaded Stainless Steel Pipe Fittings

Customize your pipe system by connecting pipes, redirecting material flow, or cutting off flow with these threaded stainless steel pipe fittings. Fittings made from stainless steel have a corrosion-resistant surface that protects the material from environmental contaminants, even if scratched. These fittings can also withstand harsh environments, such as washdown areas and areas exposed to some chemicals. They are commonly used to connect pipes transporting air, water, natural gas, and steam.

90° Elbows

Use 90° elbow fittings to make a sharp, perpendicular change in the direction of flow in your system where a small loss of flow pressure is not a problem. They are similar to 90° street elbow fittings, except they have two female ends to connect to male pipe ends or fittings.

Class 150

Class 3000

90° Street Elbows

Make a sharp, perpendicular change in the direction of flow in your system where some loss of flow pressure is not a concern with these 90° street elbow fittings. Unlike standard 90° elbow fittings, street elbow fittings have a female end and male end, so they can accept both male and female pipe and fittings.

Class 150

Class 3000

45° Elbows

Add a 45° elbow fitting to your pipe ends for a more gradual flow direction change in your system than with a 90° elbow fitting. These fittings also restrict pipe flow less than 90° elbows and have two female ends for connection to male pipe ends and fittings.

Class 150

Class 3000

Tees

Combine, change, or divide the flow of materials through pipes with the same diameter using these tee fittings. The middle port is set at a 90° angle to the connections on either end. These standard tees have three female ends to connect to male pipe ends or fittings.

Class 150

Class 3000

Crosses

Also known as four-way fittings and cross branch lines, crosses redirect the flow of material through your pipe system. They have female-threaded ends for connecting four male pipe ends or fittings.

Class 150

Class 3000

Bushings

Connect male and female pipe ends of different diameters with these bushings. A good choice for connecting pipe in tight spaces, bushings only add a small amount of length to your pipe system when connected. Their hex head helps you get a secure grip for tightening and adjusting with a wrench.

Class 150

Class 3000

Couplings

Join male pipe ends of the same diameter to create longer pipe or extend your pipe run with these couplings.

Class 150

Class 3000

Half Couplings

Weld these short fittings directly over a hole on a pipe's surface when you need to create a branch connection in your pipe system. Instead of attaching a pipe end to a pipe end, these connect a male pipe end to a surface, such as along a pipe or tank wall.

Class 150

Class 3000

Reducing Couplings

Connect male pipe ends with a larger diameter to a male pipe end with a smaller diameter to reduce the size of the pipeline using these reducing couplings.

Class 150

Class 3000

Locknuts

Lock together two threaded fittings on your pipe with these locknuts. Adding a locknut to a joint increases the joint's stability and reduces the effect of vibrations, which can loosen the fittings and cause the pipe to fail. They are hex shaped, which allows you to tighten or loosen with a standard wrench.

Class 150

Unions

Unscrew the hex-shaped nut on these union fittings with a standard wrench to install, remove, clean, or maintain pipe sections with less disruption to your system than threaded fittings that require full pipe rotation to remove. They have a two female-threaded ends for connection to male-threaded pipe ends and fittings.

Class 150

Class 3000

Caps

Stop or direct the flow of material in your pipe system and protect external threads on pipe ends and fittings using these caps. Unlike plugs, they are installed on the outside of a pipe end.

Class 150

Class 3000

Hex-Head Plugs

Use a wrench to tighten or loosen these hex-head threaded plugs inside the end of a pipe or fitting. Plugs block material flow or redirect flow in fittings with multiple heads, such as wyes or tees.

Class 150

Class 3000

Hex-Socket Plugs

These hex-socket plugs have round heads with a hex socket that can be tightened or loosened with an L-key (also known as an Allen wrench) or a hex-shaped bit. They screw inside the end of a pipe or fitting to block material flow or to redirect flow in fittings with multiple heads, such as wyes or tees.

Class 150

Square-Head Plugs

Screw one of these threaded plugs with square heads inside the female end of a pipe or fitting to block material flow or to redirect flow in fittings with multiple heads, such as wyes or tees. Use a compatible socket wrench to install.

Class 150

Class 3000

Outlets

Also called threadolet, olet, or branch connection fittings, these fittings weld directly over an outlet hole on your pipe surface to create a branch connection. They have a female-threaded end to connect a male-threaded pipe to the outlet hole.
