VIAIR 11400 DOT Air Line

This VIAIR 11400 is a 1/4" OD DOT-approved air line supplied in a 20 ft length. It is intended for automotive pneumatic systems that require Department of Transportation compliant tubing. The black colour helps identify the line in complex routing.

DOT tubing pressure and temperature limits

DOT-rated tubing must operate within the pressure and temperature boundaries defined by the standard. Exceeding those limits can cause premature failure or loss of certification. Installers should verify the system's maximum working pressure against the tubing rating.

Fitting compatibility and routing checks

Confirm that existing fittings accept 1/4" outside-diameter tubing before ordering. Measure the required run length to ensure the 20 ft coil covers the route without stretching or sharp bends. Check local regulations for any additional compliance requirements.

Questions about this item

Which length of VIAIR 11400 1/4" OD DOT Air Line should I choose for my setup?

The VIAIR 11400 is supplied as a single 20 ft roll of 1/4" OD DOT air line in black; if your run is shorter you can cut it to length, and if it is longer you will need additional rolls.

What does the 1/4" OD DOT rating mean once the line is installed on a vehicle?

The 1/4" outer diameter meets Department of Transportation standards for air-brake tubing, so it is approved for use in vehicle air-brake and accessory systems at the pressures those systems operate.

What fitting standard does the 1/4" OD DOT air line use and what pressure does that limit in practice?

The tubing is sized for standard 1/4" OD push-to-connect or compression DOT fittings, and the DOT marking confirms it satisfies the pressure requirements for automotive air-brake circuits.
