TIROL 12ft Semi Truck Air Lines Kit — 2-in-1 Red/Blue J1402 Hoses with Brass Fittings and Glad Hands

A 12-foot, 2-in-1 color-coded air line kit by TIROL designed to replace and upgrade semi-truck and trailer service and emergency brake hoses with heavy-duty fittings and temperature-resistant construction.

This ready-to-install assembly bundles the standard red and blue J1402-style air lines with rugged brass fittings, glad hands, and spare seals so drivers and technicians can complete a professional air brake connection quickly. It’s built to tolerate extreme climates and on-road stresses while matching common OEM fitments for a straightforward swap.

How does this kit speed up installation and reduce mistakes?

The TIROL kit uses factory-style color coding and polarized connectors so service and emergency lines aren’t mixed during hookup. Threaded brass fittings and non-threadlock glad hands allow fast, tool-free engagement; included spare gaskets make field repairs simpler.

• Red/blue J1402 color coding for immediate identification
• 360-degree swivel brass fittings for easy alignment
• Anodized glad hands with grip pattern for tool-free connection
• Extra rubber gaskets included for quick seal replacement

Will these hoses withstand harsh temperatures and road hazards?

Yes — the hoses are multilayer thermoelastic constructions engineered to remain flexible and intact across very low and very high temperatures. Reinforcements and corrosion-resistant fittings protect against abrasion, oil exposure, and salt, making them suitable for heavy-duty seasonal use.

• Operating range rated from -65°F to 200°F
• Triple-reinforced tubing to resist kinking and abrasion
• Brass fittings resistant to corrosion and hydraulic fluid contact
• Spring-loaded coil protectors to prevent hose collapse at docks

Are these lines compatible with common OEM replacements?

TIROL designed the kit to be a direct-fit replacement for many established part numbers and models used in long-haul fleets, simplifying upgrades and maintenance. The set mirrors standard dimensions and connector types for broad compatibility with tractors and trailers.

• Direct-replacement compatibility with several OEM part numbers
• Standard 1/2" NPT threaded brass connectors for widespread fit
• Polarized glad hands work with Freightliner Cascadia and similar rigs
• 20% thicker seals than baseline aftermarket options

What should I expect in the package and during routine use?

The kit arrives with everything needed for a complete brake line installation so technicians can finish work without sourcing additional parts. Expect long-term durability with periodic gasket inspection and the ability to swap spare seals quickly during roadside repairs.

• 12 ft color-coded emergency and service air hoses
• Two anodized glad hands and two spare rubber gaskets
• Threaded brass swivel fittings and coil-protector springs
• Instructions geared for fast, compliant installation
