Ferrule crimper for air hose?

I'm sick of using hose clamps on the ends of my air hose. I have not found a good quality clamp yet that will really hold up when I crank down on it with a nut driver.

I want to find a crimper that will let me crimp down those brass ferrules on the end of hose over a barbed end fitting. I've seen them at the welding supply for welding gas hose but those were too small for 3/8" hose.

I'm thinking some sort of ratcheting crimper like what you use for coax cable but stouter would be good. Heck, I could even build one if I knew what sort of pattern I would need. A crimper made out of bolt cutters would be sweet.

What are you using?

the one my propane guys uses to make up hoses is like a split die he uses in a vice to crimp the ends on, i'd imagine its similar for an air hose.

look around or ask the counter people at your welding supply.

I bought a hose repair kit a long time ago it had the fittings to do 3/8th air hose. They should still be around. inert gas hose is the same size I have bands and a crimper for them also that would work.

Have you ever used fuel injection clamps. i think the larger size would fit 3/8th air hose.

shop around...you find it cheaper (same or similar)-I just found that one quickly to link

A make-it-yourself AC line crimper may also work:

I saw this crimper here: http://www.righttool.com/



Looks like it would be pretty easy to make, and since I haven't seen any under $150 yet it would probably be worth my time to make a set.

Not as nice as the brass sleeves, but usable, are double ear hose clamps. You can get them, as well as a crimp tool, at Home Depot.

Are these in the tool section at home depot or what? I was just there and didn't see these.

Back when I used to manage a Napa store, we had a crimping kit that we used to fix hoses in the store, and would loan it out to shops to use. I believe it was made by Napa Tire Hardware. It came with the crimping tool, and an assortment of Brass ferrels, and fittings. Sorry I can not remember the part #, but I hope this helps.

They are in little baggies with the plumbing fittings (bottom row I think). The section where all the brass fittings are. I've never bought them there (I buy from Marshall's Industrial Hardware), but I noticed them while buying other fittings. It looked like they had a full range of sizes. I think I saw the crimper hanging on the wall with the plumbing tools. I have CV joint band crimpers that I use.

Here is the technical data sheet...

You can also use a set of bull nose cutters to crimp them if your careful.

They are a bioch to remove. You can use the bull nose cutters to cut off the crimp though.

Are they still in business? Do they have a phone # where you can talk to a person?

I work as a machinist for Greenlee tools and we make ferrule crimpers but all our tools are made for electrical use. Not sure if anything we make wouldn't screw up the nipple.

I have tried it against the crimper from McMaster and it works just as well. I have used that type of crimper to repair many dozens of air hoses. It is quick, easy, very durable, and makes a professional looking hose end.

If you know of a place to get a knockoff of that tool that works as well as the high dollar type for $30 please share. I'm going to grab a set of Oetiker clamps and crimpers next time I'm at home depot but I'd rather have the type you linked to.
