Technical Overview

This premium category features high-quality SAE J844 nylon tubing and coiled air line assemblies engineered specifically for heavy-duty truck and trailer air brake systems. Manufactured from advanced PA12 material, these products offer exceptional resistance to heat, moisture, and mechanical wear. The versatile selection includes straight air brake hoses, flexible suzi coils, and cold-weather air lines designed to withstand extreme environments. All products in this range strictly conform to DOT FMVSS 106 and SAE J844 standards to guarantee reliable performance and maximum safety on the road.


 The straight nylon tubing supports a working pressure of 150 PSI and maintains optimal durability across temperatures ranging from minus 40 to 200 degrees Fahrenheit. For dynamic connections between tractors and trailers, the heavy-duty coiled air assemblies provide superior memory and flexibility. Advanced variations feature robust heavy-duty grip handles, integrated brass fittings, and special elastomeric grips that flex during tight turns. Specialized cold-weather lines are also available, which remain fully flexible even in freezing environments down to minus 85 degrees Fahrenheit.

 

Beyond standard air lines, this collection offers complete fleet maintenance solutions including fifth wheel coils, cab blower kits, and tire inflator setups. These utility kits come pre-installed with standard NPT DOT fittings, protective short springs, and universal gladhands for easy coupling. Available in multiple industry-standard colors like black, red, blue, green, and yellow, this product line makes color-coded air line routing simple and efficient for commercial fleet operators.
