Danfoss / Eaton 3270 Eclipse Air Brake Tubing

Ask A Question

Description & Features

Designed for truck and trailer air brake systems, the Danfoss / Eaton 3270 Eclipse Air Brake Tubing is built to perform reliably under the demanding conditions of commercial vehicle brake harness assemblies, including both formed tube and straight configurations. The tubing meets SAE J844, SAE J2494-2, and SAE J1131 standards and complies with DOT FMVSS 106, making it a compliant choice for regulated air brake applications.

Constructed with a polyamide tube and synthetic fiber multi-braid reinforcement, the -6 dash size tubing features a green polyester cover rated for a minimum working temperature of -40°F. The non-conductive construction is compatible with QCAB and push-to-connect fittings, and an impulse cycle life of 125,000 cycles reflects its durability in high-demand service. Proprietary blended nylon materials contribute to a lightweight profile without sacrificing resistance to abrasion or harsh operating conditions.

Question by: Ronnie H on May 6, 2025, 8:40 PM
trying to match up tubing for a truck air brake harness, is this 3270 Eclipse stuff the right kind?
Answer by: Customer Support on May 8, 2025, 8:26 PM
Built for truck and trailer air brake systems, the 3270 Eclipse tubing is also used in auxiliary air systems and in formed or straight air brake harness assemblies.
Question by: Hugh A on Jul 14, 2025, 3:07 PM
What kind of rigs is this air brake tubing typically used on?
Answer by: Customer Support on Jul 16, 2025, 6:46 AM
Common uses include truck and trailer air brake systems, along with auxiliary air systems. It's also suitable for formed tubes and air brake harness assemblies.
Question by: Dwayne M on Apr 3, 2025, 7:00 AM
tubing's rated for -40 on the cold end, but what's the story on the upper temp limit for continuous use in a trailer brake setup?
Answer by: Customer Support on Apr 5, 2025, 6:45 AM
Cold weather performance is clearly covered at -40 degrees, and the polyamide tube with polyester cover holds up well under the thermal stress typical of air brake cycling. For continuous use on trailer assemblies, the multi-braid synthetic fiber reinforcement handles the repeated pressure fluctuations without degrading quickly. The 125,000 impulse cycle rating gives you a solid picture of long-term durability under real working conditions, which is about as reliable a benchmark as you'll find for brake harness tubing in heavy haul applications.
