Overview
When an air line lets go, the truck does not move again until it is fixed. This Air Brake Hose Repair Kit distributed by FleetPro Parts & Tires puts the repair in one box: 2 fittings and a hex key, in 1/2in NPT for 3/8in I.D. rubber air brake hose. Cut out the damaged section, terminate both ends, and the truck is back in service without waiting on a parts run or a mobile tech. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.
Back in Service Today: The Air Brake Hose Repair Kit Advantage
This kit is built for one specific air line combination: 3/8in I.D. rubber air brake hose terminating in a 1/2in NPT port. Check both the hose bore and the port thread before ordering, because a repair kit only helps when the two ends match what is actually on the truck. Both fittings and the hex key needed to set them up ship together, so nothing on the bench is missing halfway through the job. Critically for anyone who has to answer to an inspector, the kit meets S.A.E. J1402 and D.O.T. F.M.V.S.S. 106 requirements, which are the standards that govern air brake hose and hose assemblies on commercial vehicles.
At FleetPro Parts & Tires, we know the repair that happens today is the one where the parts were already on the shelf. Keep one of these kits in the service truck and one on the bench, and an air line failure becomes an hour of work instead of a tow. This Automann kit is referenced in the industry under numbers including 7031403, 500008 and 431403.
