Keep your trailer connection safe and compliant with the High Soar Air Brake Line Hose Coil Assembly. This heavy-duty 15 FT coiled air hose set is designed for semi truck tractor trailers, featuring durable red and blue air lines with 1/2" NPT brass fittings for a secure, leak-resistant connection.
Engineered as a replacement cross for popular part numbers such as Tectran 17215, Phillips 11-315, Tremec Sloan 451036N / 11-340 / 451039N, Tectran 17A15-40H and more, this coiled airline kit is built to OEM standards and complies with SAE J844 and DOT FMVSS 106 requirements for use on commercial vehicles.
The solid brass end fittings provide stable, long-term connections that resist corrosion, while the flexible air hose material maintains performance in cold weather without hardening or becoming brittle. Integrated spring tube protectors help prevent kinking and add support at the coupling points, reducing stress on the hose and extending service life.
With its coiled design, the air hose set stretches easily during coupling and returns quickly to its compact shape, helping to keep your lines organized and tangle-free between tractor and trailer. It’s a practical upgrade or replacement for worn or damaged airlines on most semi truck and trailer setups.
- OEM-style replacement for common Tectran, Phillips & Tremec Sloan coiled air line part numbers.
- Durable construction with solid brass fittings for stable, long-term, corrosion-resistant connections.
- Coiled red & blue air lines help prevent dragging, kinking and tangling between tractor and trailer.
- Spring guards at the ends provide extra protection and support for easier coupling / uncoupling.
- DOT & SAE compliant to FMVSS 106 and SAE J844 for use on heavy-duty commercial vehicles.
- Easy to install with standard 1/2" NPT fittings – ideal for fleet maintenance and owner-operators.
