I have one like you describe and have never had a problem with it.All it says on it is "C 1" Or maybe "C I". How much PSI are you running?

 

I'm using a no. 5 Koike divergent tip 106D7 for oxypropane. The tip chart calls out 100 psi cutting oxygen for 2.5" plate. I measured the pressure at the torch yesterday with the oxygen stream flowing and it was only 80psi. So I turned up the regulator to make it 100 psi at the torch. It turned out to be 120 psi at the regulator.

The hoses should stay on the batbs without the ferrule. You may be using the wrong barbs for the hose.

I don't know. The hoses that are a problem are the ones on my swingarm. I had big problems with hoses binding so the swingarm wouldn't move freely enough, so I made up some hoses from 1/4" ID Tygon. The hoses are very flexible. But I don't know if barbs on Western Enterprises fittings are best for Tygon.

 

I too have one. Around 20 yrs old. No issues.

 

By the way, I called McMaster and they refunded the price of the clamp and said they didn't want the tool back. So I still like them as a vendor.

i dont have too good a luck w/ any crimpers either. sounds like u handled it though. i know a guy, who has two half U blocks, that u pound w/ hammer, kida like a die. i use wire or hose clamps to get outa a jam.

i used to work at this family shop in the smoky mountains when i was a kid, (real nice family). anyway, the great gramps, didnt build that tool for hoses, he built it for customers who didnt pay there bill. he put the wire around there u know what, and tightened it a lil more each day. if they still didnt pay, great gramps layed them down on the welding table, and dimemebered them w/ them tools hanging on the wall, then fed them to the hogs. anything left over, got dumped down old abandoned wells, in the nearby canyon. the grandson is obviously stoned, and gramps dont even know it. the phone ringing was gramps wife wondering where he's been , but his office sexetary took care of it on second ring

I've seen that wire clamp idea before. I even made up a tool to try it once. It kind of works, but I wouldn't want to risk it on a real welding hose.

Maybe I'll make one of those two-block ones, see if I can do a better job than they did.

Since this is stationery and not getting dragged all over the shop how about using the small worm drive clamps?

 

My C 1's work fine.

I believe you. If you look closely, a crimp done with that tool would have 4 ridges standing out from the ferrule. That same tool today is made differently. A crimp made with the tool sold today would have 2 dimples, one on each side. If you look closely the ends of the two half-blocks don't even line up. And, worse, it's made in the USA according to the packaging.

I have an extra. Still new in the box. PM me your address and I’ll ship it out to you.

I got it today, thank you so much!

When I'm done with it I promise to pass it along to someone else who can use it.

Just FYI, max pressure for that tubing is 62psi, and that is at 73* F. Add the heat of the cutting operation and you are probably maxed out at 15 pounds or so.

 

I much prefer the Oetiker O-clamps over the crimped brass ferules. Never had one come apart.

Same. But ferrules are nice to make everything look OEM tho.

SHOULD have used ferrules here (regulator end)....

I use hose clamps.
I seen shop made ones they just drill hole in flat bar and weld to bar hole in place. Easy to use hit harmer. I have hit Vise-Grip ones did not work as shop made.
But crimp on type is pain to remove and it is one time use.
So I started using hose clamps from automotive store.

I am about to purchase a kit for oxy/fuel and one for inert. Can I get some opinions on which is more preferred, a new kit with vice grip or hammer?

 

I've only used the hammer type. One would think a long handled swage type tool similar to one used connectors for wire rope would work best.

I also like using

Oetiker clamps like WelderDave mentioned.

I dislike gear type clamps for this application. Even when when using the optimum size there's always that "tail"hanging out.

Is there any difference between regular pneumatic air hoses and welding gas hoses, as far as the fittings and crimps are concerned? I was looking to make/fix some pneumatic hoses and got to thinking my welding cart would look a bit more tidy with shorter hoses.

I'm familiar with and have the tools to crimp battery lugs/cable from 6 gauge up to 4/0. It would be awesome if my hydraulic crimper could be used to also crimp hoses, but finding dies to fit could be challenging.

 

Welding hoses are flame resistant to a point and the nuts are specific for oxygen and fuel gas connections. Generally thicker wall than air hose and both hoses are joined together. Having separate hoses is a real PIA. They get caught on anything and everything. Fuel gas nuts are left hand thread so they can't be mixed up. You don't need a hydraulic crimper for welding hoses.

 

I was thinking of picking up the Pex pipe pliers and rings to repair 3/8 and half inch air hoses. Reading this discussion over, is there going to be a problem getting collars that fit unless I go to a different supplier? Are the Pex crimps not going to be tight enough?

 

Just get a handful of Oetiker clamps and use something like a CV boot clamp tool or end cutting pliers.

That is the cheapest way and still look pro.

Using the small automotive gear style clamps is for amateurs, plus the “tail end” always snags on sh*t. LOL.

Oh and Pex 1/2" and 3/8" will not correspond in size to inert gas hose sizes.

I've always tossed the gas hoses rather then mend them... it's usually the first sign of impending disaster unless you're changing the length or fitting. I was thinking more about air hoses. My 1/2" ones are still fairly new, but some of the old 3/8" could use attention.

 

I use Oetiker for air also
