The air lines on my coach are 1/4" OD. Air system lines are usually made of nylon and are rated at 150 psi max. They come in several colors. Mine are red and green for brakes and suspension, with yellow for parking brake system.

Be sure to route them carefully, avoiding sharp bends and heat.

Mine are 1/4” also but depending on the chassis it may have 3/8” or if it has ping tanks, 1/2” or 5/8”. Just measure the outside diameter and you’ll be good.

Thank you for your replies. I had issues 3X in the mountains and desserts where the line was too close to the diesel turbo unit exhaust. I want to carry some spare line and fittings next time I take a trip.
