Pipe, Tubing, Hose, and Fittings

Standard-Wall Aluminum
Unthreaded Pipe and Pipe Fittings

Choose standard-wall pipe and pipe fittings when you need a thicker wall and better strength than our thin-wall aluminum pipe and pipe fittings.

Thin-Wall Aluminum Unthreaded
Pipe and Pipe Fittings

These have the thinnest walls of all our aluminum pipe and pipe fittings.

Thick-Wall Butt-Weld Aluminum
Unthreaded Pipe and Pipe Fittings

The strongest unthreaded aluminum pipe and pipe fittings we offer, these have extra-thick walls for excellent strength.

Low-Pressure Aluminum
Threaded Pipe and Pipe Fittings

Use in low-pressure applications up to 150 psi.

Medium-Pressure Aluminum
Threaded Pipe Fittings

Use in medium-pressure applications up to 500 psi.

High-Pressure Aluminum
Threaded Pipe and Pipe Fittings

Use in high-pressure applications up to 3,000 psi.

Tube Fittings for Metal Tubing

Fittings are designed for medium- to high-pressure applications. They connect to tubing or pipe.

Tube Fittings for Plastic
and Rubber Tubing

Connect to tubing or pipe, typically in low-pressure applications.

Air and Water Hose Fittings

Use these fittings in a variety of general purpose air and water applications, such as plumbing, water supply, and pneumatics.

Chemical and
Petroleum Hose Fittings

Other Elbows

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.

Medium-Wall (IMC) and Thick-Wall
(Rigid) Conduit and Fittings

With thicker walls than thin-wall (EMT) conduit, this conduit provides better strength and protection from impact in heavy duty applications.

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.

Slip-On Framing and Fittings

Slip these fittings over rails to construct custom railings, guard rails, storage racks, and shelving.

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.

Clamp-On Framing and Fittings

Fittings come in two pieces to wrap around rails, so you can quickly modify existing structures without disassembling. Use clamp-on framing and fittings to form temporary partitions, modular conveyors, and workstations.

Flow-Adjustment Valves

Manually adjust the flow of oil to a single lubrication point.
