How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Standard-Wall Butt-Weld Aluminum
Unthreaded Pipe Fittings

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

Thin-Wall Butt-Weld Aluminum Unthreaded Pipe Fittings

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

Thin-Wall Socket-Connect
Aluminum Unthreaded Pipe Fittings

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

Thick-Wall Butt-Weld Aluminum
Unthreaded Pipe Fittings

Thick walls give these Schedule 80 fittings excellent strength.

Low-Pressure Aluminum Threaded Pipe Fittings

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Medium-Pressure Aluminum Threaded Pipe Fittings

Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum pipe fittings.

High-Pressure Aluminum Threaded Pipe Fittings

Also known as Pressure Class 3000 fittings, these have the highest pressure rating of all the aluminum pipe fittings we offer.

37° Flared Fittings for Aluminum Tubing

Also known as JIC (Joint Industrial Council) fittings, these provide a tight seal on tubing that is flared to 37°.

Aluminum Low-Pressure Barbed
Tube Fittings for Air and Water

Aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Choose-a-Color Aluminum Low-Pressure
Barbed Tube Fittings for Air and Water

Color-code fittings for easy identification. These aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Screw-On Nut Barbed Tube Fittings for Air

You don't need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to holds the tubing in place.

Threaded Swivel Hose Fittings for Air

Connect these fittings to air tools for pneumatic applications.

Metal Cam-and-Groove Hose Couplings for Water

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.

Metal Cam-and-Groove Hose
Couplings for Chemicals and Petroleum

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Conduit and Fittings

Connectors for Rigid Aluminum Conduit

Join pieces of conduit.

Hazardous Location Conduit Access Ports

Also known as conduit bodies, these ports provide access to wire and cable inside thick-wall (rigid) metal conduit for pulling, splicing, and maintenance. They are also used to change the direction of a run.

Access Ports for Metal Conduit

Also known as conduit bodies, these ports provide access to wire and cable inside metal conduit for pulling, splicing, and maintenance. They are also used to change the direction of a run.

Standard Duct and Fittings

No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.

Structural Framing

Aluminum Slip-On Framing and Fittings

Half the weight of steel, this aluminum framing resists corrosion in wet environments.

Carbon Fiber Slip-On Framing and Fittings

Stronger than plastic and aluminum, this is the lightest weight framing we offer. It has good resistance to chemicals and salt water.

Heavy Duty Clamp-On Framing and Fittings

Thick construction makes this framing strong and sturdy.

Flush-Fit Framing and Fittings

Flush connections between rails and fittings give structures a clean finished look. Use this framing for stair rails, work platforms, and workstations.
