Nylon DOT tubing is made from a unique material derived from the seeds of the castor bean plant. It is primarily used as brake line tubing. Also known as Polyamide 11, Nylon 11 is an extremely tough plastic that can withstand extreme temperatures and resist harsh chemicals. It is ideal for connecting instruments and pneumatic accessories to the air brake system, and meets SAE J844 standards. Two types of nylon DOT, Type A and Type B, are available.

Type A DOT tubing is 5/16” OD or less. It is rugged enough for critical vehicle systems but is flexible enough to fit in tight spaces. Type B is for sizes above 5/16” and requires a braid inside the tubing.
