DOT Nylon Tubing

D.O.T. nylon Tubing is a specialized, high-pressure hose specifically designed for air brake and pneumatic systems. The DOT tubing is made from Virgin 12 Nylon 12 material with a double-wall construction, nylon core, synthetic fiber braid, and nylon cover, ensuring durability for rugged applications. The DOT tubing meets or exceeds DOT FMVSS 571.160 & SAE J844 standards to offer excellent resistance to abrasion, fuel, and road salt.

Polyconn offers several sizes and diameter options of our Nylon 12 DOT tubing from our specialty tubing products. Contact our sales team for more information or to find the right tubing for your needs.

Nylon 12 DOT Tubing Overview

DOT tubing is constructed from heat- and light-stabilized Nylon 12 material with a reinforced braided inner wall. The Nylon 12 material provides high-performance, durability, and chemical resistance for top use in air brake systems and other pneumatic systems in automotive. The unique makeup of DOT tubing operates under high pressure and temperatures ranging from -40°F up to 200°F, providing a strong tubing option for extreme applications.

DOT Tubing Compliance & Standards

Polyconn’s DOT nylon tubing meets or exceeds DOT FMVSS 106 standards established by the U.S. Department of Transportation (DOT) for use in air brake systems on commercial vehicles. Manufactured to specifications such as SAE J844, the tubing is designed to withstand high pressure, temperature variations, vibration, and exposure to road chemicals. The compliance set down requires rigorous testing for burst pressure, tensile strength, flexibility, and dimensional stability to ensure reliable performance in critical braking systems. These standards help maintain the integrity and safety of pneumatic brake systems used in trucks, trailers, and other heavy-duty vehicles.
