Phillips Industries Heavy Duty Coiled Air Brake Hose Assemblies

Phillips Industries Heavy Duty Coiled Air Brake Hose Assemblies are professional-grade pneumatic connections engineered for the demanding requirements of commercial tractor-trailer operations. Trusted by virtually every major tractor and trailer manufacturer in North America, Phillips air brake coils are a proven standard across Class 8 trucking and the commercial vehicle aftermarket.

Each assembly is purpose-built to deliver safe, dependable air transfer between tractor and trailer braking systems. The coiled design prevents kinking, tangling, and premature wear during normal vehicle operation, while purpose-engineered fitting geometry minimizes stress at connection points and extends overall service life.

Key Features:

• Industry-standard nylon tubing construction provides exceptional durability, flexibility, and long service life across a wide range of operating conditions
• Brass end fittings with plated steel springs deliver robust strain relief and long-term connection reliability, minimizing tubing wear and preventing cracking or fraying
• Thread seal included for secure, leak-free connections to gladhands and chassis fittings
• Single-piece trailer side and three-piece swivel tractor side fittings for straightforward installation
• Built to working length so the coil does not kink and gladhands remain secure under excessive pull force
• Maintains flexibility in extreme cold weather conditions down to -40°F (-40°C)
• Meets SAE J844 and J1131 industry specifications
• Compliant with DOT 49 CFR FMVSS 571.106 and FMVSS 393.45 federal safety standards
• Temporary protective fitting caps included to protect thread seal from debris during storage and installation

The vertical orientation at the tractor end and angled design at the trailer end are engineered to minimize hose kinking and extend service life. For assemblies with longer leads, use of a tracker bar spring kit or pogo stick support is recommended for proper hose management.

Multiple configurations are available within this product line to suit a wide range of commercial trucking applications — including single hose and matched pairs in emergency and service designations. Phillips Industries has been a trusted manufacturer of commercial vehicle components since 1928, with more than half of all trailers manufactured in North America equipped with at least one Phillips part.
