Pipe, Tubing, Hose, and Fittings

Vacuum Fittings for Steel Tubing

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.

Aluminum Quick-Connect Pipe
Fittings for Compressed Air

Twist these fittings onto aluminum pipe for quick, sealed connections—no threading, soldering, or welding necessary. Use them to build a compressed air system in half the time it would take to build a copper or steel system.

Metal

Easy-to-Machine Gray Cast Iron Tubes

Gray cast iron machines faster with less wear on cutting tools than most types of steel. It's often fabricated into gears, pulleys, rollers, and bushings.

932 Bearing Bronze Tubes

Offering excellent antifriction qualities, 932 bronze also offers good strength and wear resistance. It's also known as SAE 660 and is often used for bearings, bushings, and thrust washers.

Weldable 954 Bearing Bronze Tubes

954 bronze contains a minimum of 10% aluminum for strength and weldability. It is also known as aluminum bronze. It's widely used for bearings, bushings, valve bodies, and worm gears. The strength of this material increases with heat treating.

Easy-to-Machine 936 Bearing Bronze Tubes

An easier-to-machine alternative to 932 bronze, 936 also has better corrosion resistance. It's also called modified SAE 64.

High-Strength 863 Bearing Bronze Tubes

Frequently called manganese brass, 863 bronze can handle heavy loads and high speeds when properly lubricated.

Plastic

Clear Scratch- and UV-Resistant Cast Acrylic Tubes

Cast acrylic is easier to machine than extruded acrylic. It's comparable to Lucite and Plexiglas® Acrylic.

Easy-to-Machine Wear-Resistant Cast Nylon Tubes

This cast nylon 6 material is easier to machine than other types of nylon. It’s comparable to Nylatron and Nycast.

MDS-Filled Easy-to-Machine
Wear-Resistant Cast Nylon Tubes

The addition of MDS gives these tubes exceptional wear resistance along with a self-lubricating surface. They're made of cast nylon 6, making them easier to machine and better electrical insulators than other MDS-filled nylon tubes.

Oil-Filled Easy-to-Machine
Wear-Resistant Cast Nylon Tubes

This nylon stays lubricated over time because it’s filled with oil. Use it to fabricate parts for hard-to-reach places where adding lubricants would be difficult.

Heat-Stabilized Easy-to-Machine
Wear-Resistant Cast Nylon Tubes

A good choice for making sprockets and pulleys, these cast nylon 6 tubes withstand higher temperatures and are easier to machine than standard nylon 6/6 tubes.
