Tubing is welded with a smoothed weld bead on the inside to reduce particle buildup. It is also known as DOM (drawn over mandrel) tubing.

A thin layer of zinc yellow-chromate gives this tubing extra corrosion resistance, making it an economical alternative to stainless steel.

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal.

The external hex bolt on these fittings allows for easy installation in cramped spaces.

These fittings have two sleeves for extra gripping power. They bite into steel tubing as you tighten the nut to form a strong seal.

Assortments contain threaded pipe in various lengths.

A plastic sleeve prevents destructive corrosion when connecting different metals.

Assortments contain threaded pipe in various lengths.

Typically used with medium-pressure iron and steel threaded pipe fittings. Also known as Schedule 80.

Typically used with high-pressure galvanized iron and steel threaded pipe fittings. Also known as Schedule 160.

Typically used with standard-wall and low-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 40.

Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80.

This steel pipe has grooved ends that connect to fittings with a clamp (sold separately) for an easy way to install piping systems.

Formed by metal interlocked strips, this hose has the strength to stand up to sharp, abrasive materials.

Transfer fluid between pumps, cylinders, and other parts of your hydraulic system with this hose that has attached fittings to save time and eliminate points of failure.

To transfer air or oil- and water-based paints, attach this hose to a paint-spray system that has separate hoses for air and paint. Fittings swivel until tightened for easy installation. Fittings with spring guards prevent kinking.

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

4130 alloy steel has a low carbon content that provides good weldability. It's often used for gears, fasteners, and structural applications.

Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as axles, shafts, collets, and die holders. It resists fracturing from repeated stress.

Attach conduit to a knockout in an outlet box or enclosure.

When used with liquid-tight fittings, this conduit seals out liquid. The steel core provides crush resistance, and the cover is UV light resistant.

Even in temperatures as low as -50° F and as high as 220° F, this conduit stays flexible.

Run conduit in food areas—the cover can be cleaned and sterilized without weakening or splitting. This conduit meets NSF/ANSI standard 169 for special-purpose food equipment.

Join pieces of conduit.

Visually identify different runs of wire and cable along walls and ceilings with this conduit that has a painted exterior.

Attach conduit to a knockout in an outlet box or enclosure.

Attach conduit to a knockout in an outlet box or enclosure.

Reduce the knockout size in an outlet box or enclosure so you can attach a different size of conduit to it.

This impact- and crush-resistant conduit is also known as galvanized rigid conduit (GRC).

Attach conduit to a knockout in an outlet box or enclosure.

Connect different sizes of conduit.

Screw and nut sets or nuts secure brackets and other accessories to rails.

Add panels to T-slotted framing to create machine guards, strip doors, and welding curtains.

Stay organized with hooks, bin boxes, shelves, and tool holders that work with T-slotted framing.

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

Half the height and the same width as regular strut channel, this low-profile strut channel fits into tight spots and is compatible with many of the same brackets.

Slide the strut channel into the tube for telescoping length adjustments.

Up to two times the height of regular strut channel, this high-profile channel is stronger than regular strut channel.

This welded, one-piece strut channel combines two strut channels side-to-side.

A spring plus serrated grooves that grip the lip of the channel provide a more secure hold than standard strut channel nuts.

Serrated grooves grip the lip of the channel.

Keep a rod securely centered against the strut channel.

Also known as insert nuts, these convert slotted holes to threaded round holes and keep them centered in the channel.

There's no need for additional fasteners with these nuts—they combine a strut channel nut with a spring and a threaded stud.

A tab fits tightly against the lip of the channel to keep these nuts from slipping.

Add hardware to strut channel without having to hold the washer in place or reach inside the channel.

Use with hex nuts to connect threaded rod.

Designed to wrap around the sides of strut channel, these brackets provide a stronger hold than other strut channel brackets.

These brackets have narrow slots compatible with quick-connect clamps for securing pipe and conduit on the channel side of struts without screws or tools.

Brackets mount on the outside of strut channel to allow trolley movement.

Cover rough ends of strut channel.

A tab on the end of these shelf brackets fits inside the strut channel for extra stability.

For quick mounting of components, these hangers snap into strut channels for a strong hold and easy repositioning.

Provide smooth motion between two pieces of strut channel.
