6" Lengths: 0° to 180° F
All other sizes: -20° to 180° F - Tensile Strength: 7,690 psi (Good)
- Impact Strength: 1-1.5 ft.-lbs./in. (Poor)
- Hardness: Rockwell R120-R122 (Hard)
- For Use Outdoors: No
- Specifications Met: See table
Easy to machine to close tolerances, these dimensionally stable tubes resist expanding when exposed to heat and moisture. They have a naturally slippery surface along with excellent wear resistance. Use them to make precision gears, bushings, and bearings. Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.
Tight-tolerance tubes that are 6” long are also known as bushing stock. You can slide them over rods to increase the OD, or into shafts to decrease the ID. Their precise sizing also allows ascending sizes to fit inside of each other to increase the wall thickness.

Slippery UHMW Polyethylene Tubes

These impact- and wear-resistant tubes offer 360° protection from scrapes and strikes to wires, cords, and anything that can slide through them. UHMW has a low-friction surface that resists sticking and binding.
Tight-tolerance tubes, also known as bushing stock, slide over rods and inside shafts to increase or decrease the diameter. Their precise sizing allows ascending sizes to fit inside each other to create a thicker wall.
