Just when you least expect it, POP; your air hose springs a leak. Hopefully it doesn’t just blow apart, and the end connected to the compressor whips at your legs like an angry cobra, but rather a small leak. Regardless, you still need to fix it. You could go out and buy a new hose, but if you are using a high-dollar air hose, that can get really expensive. Don’t fret, for about $5, you can fix it yourself.
You will need the following to properly repair a high-pressure (up to 120 psi) air hose:
-Threaded Hose barb to match your hose
We used a Mastercool hose crimper, which uses a series of dies to crimp hose fittings. You can use any hose crimping tool, and if you don’t want to buy one (they are incredibly handy), you can rent them from your local auto parts store, or they can crimp the hose for you.
First, the hose is cut. Depending on what type of break it has: split, pinhole, etc, will determine how much you need to cut off. Make sure that you cut out all of the bad hose, or you are just looking at another blowout.
Slide the ferrule over the hose all the way to the end. Then install the barbed fitting all the way into the hose until the fitting is seated to end of the ferrule.
Next, open the crimping tool and load the dies for the correct hose size. Then place the hose end into the crimping dies and close the crimping tool.
Compress the crimping die tool to complete the crimp.
Now you have a freshly-terminated hose, ready for action. If the break occurred in the middle of the hose, you can install another fitting to create two shorter hoses. Remember to test your fittings by slowly increasing the air pressure and use soapy water to look for bubbles. If you need any assistance repairing your hose, a visit to your local auto parts store will get your fixed up.
