This high-quality air brake tubing constructed from proprietary blended nylon materials is designed for truck and trailer brake systems. It delivers maximum durability under demanding conditions and features premium abrasion resistance.
The yellow color aids in easy identification during maintenance and installation. Engineered with synthetic fiber reinforcement and multi-braid construction it ensures reliable performance over an impulse cycle life of 125 000 cycles.
The 2.5-inch minimum bend radius allows for greater adaptability in complex configurations. Conforming to DOT FMVSS 106 standards this tubing meets SAE J844 SAE J2494-2 and SAE J1131 certifications making it suitable for auxiliary air systems and harness assemblies. The lightweight design also contributes to enhanced hose flexibility.
got a tight spot behind the axle, how tight can you bend this 5/8 yellow air brake tubing without kinkin it

For routing in cramped areas, the minimum bend radius is 2.5 inches. Staying at or above that bend radius helps keep the tube from being forced into a kinked shape.

tubing's rated for -40 on the cold end, but what about heat, how hot can it actually run before it starts giving out?
Answer by: Customer Support on Dec 6, 2025, 6:13 AM
Cold temp is listed at -40 degrees, but the upper working temperature isn't specified in the available data for this tubing. What is confirmed is the DOT FMVSS 106 compliance and SAE J844 certification, which are the governing standards for air brake tubing used in truck and trailer brake systems. Those standards do set performance thresholds, so if you're running a standard brake or auxiliary air application on a commercial rig, this tubing is built to meet those requirements. For extreme heat environments beyond typical brake system operating ranges, you'd want to verify against the full spec sheet for the upper thermal limit before committing.
