Coiled Hose Repair

[asallwey]

Any secrets how to put a new fitting on a coiled (nylon?) 1/4" yellow hose? The cheap kind sold every where. I've watched a couple of youtube videos where it looks so easy, but it didn't work like that for me. The damn hose is really tough when you don't need it to be!

I've held the end in boiling water for at least a minute and still can't push the barb fitting in more than 1/2 way, it went over the 1st barb, didn't get to the 2nd.

Heat gun heated too much of the hose and it would kink trying to get the barb in, and it only went on like above.

Just got a compression fitting with a barb end. The barb looks like it will go in (smaller than I used above), but the cap doesn't want to slide over the hose. Of course the hose isn't round, but more oval. Haven't tried heating the hose to squeeze it in the cap yet.

Just thought I'd ask here for success stories.

I had a cheap POS coil hose that leaked so I tossed it in the garbage and NEVER purchased a cheap hose again....... Cheap is expensive!

It probably costs more for a replacement fitting than it costs to buy another one of those cheap hoses. If your time has any value, it CERTAINLY costs more.

Actually they are quite durable, but it is possible to hole them. The purchased fitting cost me under $6 and eventually will get used elsewhere. The first one was the original barbed fitting that came on the hose. These hoses are cheap, but I have this thing about throwing stuff away without trying to fix it first.

Don't go with a barb fitting. Get a compression fitting and the proper sized hose insert.

I was forced to work with those horrible coiled hoses at a previous employer. Low air volume, poor air pressure, car-paint-damaging junk. Give me a reinforced rubber hose that lays on the ground instead of scraping the fender.

When it was time to equip my own shop, I used REAL air hose.

I have a decent quality 3/8" coil hose mounted above my bench. The end is secured to an auto retracting tool cord that keeps it up out of way, but in easy reach for a quick dust off.

Compression fitting is best. Another possibility is a "push in" fitting (SMC calls them one-touch). Look at McMaster carr's catalog or google search SMC KQ2 fittings for more. Need to measure tubing OD correctly, 1/4" and 6mm hoses require different fittings, except for Legris which seems to be the only one which can handle both. Numatics, Legris, SMC all make entire lineups of these fittings. I've purchased them on ebay before. Its kind of like a sharkbite in concept. Used in industrial automation and mechanical "air logic" controls.

I think the best reason for my problem is that it may be a 6mm hose rather than 1/4". It's not printed on the hose, so I was just guessing. Plus the barb on the original fitting is 0.258 - 0.290 on the low/high points where as the compression fitting barb is 0.232 on the high point. I think I'll just toss it in the 'later' pile. I like the coiled hoses for some things, like the end of the line air filling tires. The coils do have a mind of their own so best not to let them get hooked. My air comes into the garage via black pipe, then rubber hoses. O well, got better things to do than keep playing with this!

Thanks all!

I am sure they have a place but tried a couple and found I really got no use for them.

Use 1/2” ones as a leader off rear of my semi wrecker to truck being towed when I’m supplying air to it. Cools allow to stretch in turns and not to hang on underlift going straight

Other than that I have no use for that garbage
