This Eaton 3270 Eclipse Air Brake Tubing is engineered for superior performance in truck and trailer air brake systems. With premium abrasion resistance and UV stabilization it provides extended durability even in the harshest conditions. The tubing is constructed from polyamide with polyester yarn reinforcement ensuring high strength and flexibility.
Featuring a 0.50-inch outer diameter and a 0.06-inch wall thickness it offers enhanced flow performance and a minimum bend radius of 2 inches for versatile installation. This non-conductive multi-braid tubing meets SAE J844 J1131 and J2494-3 DOT-FMVSS 106 standards making it highly reliable for critical applications.
Ideal for auxiliary air systems formed tubes and straight air brake harness assemblies it operates effectively within a temperature range of -65deg;F to 200deg;F. The tubing is easy to cut burr-free simplifying assembly processes. The red color ensures easy identification and safety compliance in industrial environments.

tubing says it goes down to -65°F but the working temp listed somewhere else shows -40 -- which one do I actually trust for air brake use?
Answer by: Customer Support on Jul 5, 2025, 3:19 PM
The operational temperature range for this tubing runs from -65°F up to 200°F, so cold weather flexibility is built in at the material level. The -40 figure you're seeing refers to the minimum working temperature under pressurized service conditions, which is the more conservative rating you'd apply when the system is actively pressurized and cycling. For general installation and routing in cold climates, the tubing itself stays pliable well below -40. For a pressurized air brake system in regular use, plan around that -40 lower limit.
