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.
