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.

Tubes with an oversized OD also have an undersized ID for finishing to the sizes listed.

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

Color: Brown
Temperature Range: -40° to 185° F
Tensile Strength: 7,690-8,100 psi (Good)
Impact Strength: 0.7-1 ft.-lbs./in. (Poor)
Hardness: Rockwell R115-R118 (Hard)
For Use Outdoors: No
Specifications Met: See table

PTFE is added to these Delrin® acetal resin tubes to make the surface even more slippery and wear resistant. They resist expanding when exposed to heat and moisture, so they can be machined to close tolerances. Fabricate them into pump components, gears, and bearings. The OD is oversized and the ID is undersized for finishing to the sizes listed. Delrin® acetal resin is also known as acetal homopolymer.

Moisture-Resistant Hard Plastic Tubing for Air and Water

Rigid
Compatible with Compression Tube Fittings
Hard (Rockwell 120)
Temperature Range: -20° to 180° F

Made of moisture-resistant acetal, this tubing won’t soften and lose strength, even in high-humidity environments. Tubing is opaque, so you cannot see what’s flowing through the line. It is rigid and will not bend.
