Other Tubing

Multipurpose 4140 Alloy Steel Tubes

testString

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.

Multipurpose 6061 Round Tubes

Stainless Steel

testString

With a minimum of 10% chromium content, stainless steel is known for corrosion resistance. It's typically not as strong as steel and can be more difficult to machine.

Brass

Brass alloys consist primarily of copper, but they can contain as much as 40% zinc, which increases their machinability. They are often used for nuts, rivets, hinges, and locks.

Bearing Bronze

testString

A combination of low friction and high wear resistance makes these alloys the best choice for use as bearings. Bearing bronze includes alloys 544, 840, 841, 863, 932, 936, 954, and AMPCO 18.

Clear Plastic

Use clear plastic for windows, instrument covers, display cases, and other applications where visibility is essential.

Wear-Resistant Easy-to-Machine
Delrin® Acetal Resin Tubes

Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

Wear-Resistant Nylon

Nylon offers excellent resistance to wear caused by friction.

Slippery UHMW Polyethylene Tubes

In addition to a low-friction surface that prevents sticking and binding, this tough material is impact and wear resistant to handle the scuffs, scrapes, and strikes that other plastics can’t.

Sleeving

Bundle wire, cable, and hose to protect from abrasion and the environment.

Garolite

Garolite, also called phenolic, provides a good balance of strength and heat resistance.
