Applications
Used on rubber tractor-trailer airlines and shop-built airline assemblies that require field-repairable splice or end fittings. Common uses include:
- Tractor-to-trailer airline repair (service and emergency)
- On-vehicle airline patching where pneumatic crimp tools are unavailable
- Repair of damaged sections without replacing the full hose run
- Heavy-duty trucks, tractors, trailers, and tankers with 3/8″ rubber airlines
Confirm hose ID and pipe-thread size before ordering. This kit is for 3/8″ ID rubber airline only — nylon airlines and 1/2″ hose require different fittings.
