Fixing a Crimped Compressor Hose




On the plastic compressor hoses, if the spring isn't in place, sometimes the hose will crimp near the nipple, and a) not deliver enough pressure and/or 2) develop a leak at the site of the crimp.  Here's what I did to fix that, and prevent it from happening again.

Step 1: Remove Nipple, Repair Hose

 I cut the hose above the crimp, and removed the remaining piece from the nipple.
You may have to use an x-acto knife or a cutting tool to cut through the hose piece; it's fairly tough.

Step 2: Reinsert the Nipple Into the Repaired Hose

 You may have to use a couple of pairs of pliers to force these pieces fully into place.

Step 3: Affixing Spring Into Place

 Keeping the spring in place is what keeps this hose from getting crimped.
One way to make it stay is use a dab of Shoe-Goo.  Thanks to my wife Carolyn for this tip!

    For barbed fittings, just inserting them like that is not going to be secure.  You must use hose clamps.  I would not consider that hose safe for more than 10psi.

    Those fittings are engineered just for this type/size tubing. I have personally used them at 120 psi in industrial applications many times with no clamps and they lasted for years, or until someone cut or mangled the tubing.... I have also seen the type you are referring to, some DO have to have clamps or get ready to get slapped with hose - I have been there too!

    The only correct way to make a repair that will last is to make the repair as follows:  Heat the air line slightly with a heat gun to soften it long enough to slide the fitting in. Let it cool, then slide the spring back down and you have made a repair that will last a long time. If you don't heat the air line, forcing the fitting in will result in a failed repair and  wasted time. When you make the repair using the heat gun you will not need clamps and it will last.  Do this with all air lines when inserting a new fitting.

     Perhaps.  Hose clamps might be hard to tighten over the springs.  I did have difficulty getting the short piece off; had to cut it off.  
    But this hose came this way... and didn't fail except to get crimped when the spring was not in place.  Thanks for the recommendation though... I'll try that myself and report back how well they tighten over the springs.

    I would put the hose clamp before the spring and put the spring just after it.  The spring is going to prevent the clamp from working.
