An air hose repair end is a fitting that replaces the damaged end of an air hose, so the hose works again without buying a whole new hose. Pick the fitting by hose size and thread, matching the barb to the hose and the thread to the tool or compressor port. Measure the hose and the port first, then buy the fitting that matches both.

What is an air hose repair end?
An air hose repair end is a fitting that takes the place of a cut, cracked or worn hose end. A barb slides into the hose, the fitting tightens over the hose to hold the barb in place, and a thread on the other end connects to a tool or compressor port. The repair saves the rest of the hose, which is the point when the damage sits near the end and the hose itself is still sound.
How to pick the right repair end
- Hose size: match the barb to the hose inside diameter. A 3/8 inch barb fits a 3/8 inch ID rubber hose, and the Road Superior kit fits 3/8 inch ID air brake hose.
- Thread: match the thread to the port. The Pronese fitting has a 1/4 inch NPT thread, the Road Superior kit has 3/8 inch NPTF threads, and the Metabo HPT kit has a 1/4 inch NPT male end.
- Hose type: the fitting must suit the hose. The Pronese fitting is only suitable for rubber hose, the Dazakoot and Road Superior kits are for air brake hose, and the Metabo HPT kit is for 1/4 inch poly air hose.
- Pressure: check the fitting pressure against the system. The Dazakoot fitting lists a maximum working pressure of 350 psi, and the Pronese fitting lists a maximum pressure of 300 psi.
How to fit an air hose repair end
- Cut: cut off the broken part with a pipe cutter, so the cut is flat.
- Fit: put the nut, ring or sleeve over the hose before the barb goes in.
- Barb: insert the barb end into the hose inside.
- Tighten: use a wrench to tighten the fitting, and the hose is ready again.
The Dazakoot fitting fastens with one wrench, and the Road Superior kit includes a hex wrench with pre-applied thread sealant on the fittings. The Pronese fitting needs an adjustable wrench, a pipe cutter and Teflon tape, and the pack includes the tape.
The gear: air hose repair ends
The fittings below handle the repair itself, from the barb that goes into the hose to the thread that connects to the tool, so pick by hose size and thread.
Drain the tank after use so water does not rust it from the inside, never exceed the tool's rated pressure, wear eye protection, and run 240V units on the circuit the manual calls for. Do not run a gas engine compressor in a closed garage. Read our Safety Disclaimer.
