Nylon D.O.T. tubing is made from nylon 11 resin, a unique material derived from castor beans, and is primarily used as break line tubing. Also known as polyamide 11, nylon 11 exhibits outstanding abrasion, chemical, impact, moisture, and thermal resistance, and excellent dimensional stability. It is ideal for use with instrumentation and pneumatic accessories that are connected to the air brake system. D.O.T tubing is required to meet SAE J844 specifications, and comes in two varieties: Type A and Type B.
 
Type A D.O.T. 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.
 
Freelin-Wade currently produces type A nylon 11 D.O.T. tubing which meets SAE J844 specifications. We offer D.O.T. tubing in a wide range of sizes and colors, along with customized tubing that is tailored to your unique needs.

Nylon Air Brake Tubing for Heavy Duty Vehicles

Freelin-Wade’s nylon 11 air brake tubing is heat and UV stabilized, making it highly resistant to stress-cracking and, therefore, ideal for outdoor applications with significant sunlight exposure. Our D.O.T. tubing is available in sizes 5/16” OD and smaller, and six standard colors are available (color availability varies by size). We offer air brake tubing in 100’ lengths or on easy-to-dispense reels (up to 2,000’).
 
Please note that we offer only Type “A” air brake tubing; we do not offer larger, Type “B” reinforced air brake hose.
