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

Because this 6/12 material absorbs less water than standard nylon 6/6, it holds its shape better. It’s often machined into hose fittings and valve components.

Designed for extreme wear resistance, this Kevlar-filled nylon 6/6 material lasts up to 20 times longer than unfilled nylon. Also known as Hydlar Z, it is often used for parts that are continuously exposed to wear and abrasion, such as wear strips and bushings.
