Also known as nylon 6/6, this general purpose material is often used for bearings, gears, valve seats, and other high-wear parts.

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.

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.
