TIG water hose repair?

[Kelvin]

My Sync 250 has a short 18" water hose carrying warm water from the DINSE connector on end of torch to the input side of the cooler pump, and the hose sprung a pinhole leak.

With shipping and small-order fees, I'm looking at almost $50 for a new one. Machine was new in 2010.

I was going to try to seal the pinhole with some 3M 5200 Marine Adhesive Sealant and maybe some fabric wetted out with same to tie it all together.

Has anyone repaired something like this, and if so, how? I think the ends are pressed on (11/16" LH nut on pump end, 7/16" RH nut on DINSE connector end) -- otherwise I would just try to use a new piece of hose.

Thanks for any help.

Those fittings are standard hose barbs. You can cut the bands and pull them out.
Then find a piece of hose from a welder supply or industrial rubber supply, some times
home depot or lowes. Then just use what ever hose clamp you can find to put it back together.
The welding supply or industrial rubber should have the bands (ferrels) and the tool to assemble them. Repairing is a short term fix. Once the rubber starts to break down and leak. It will leak in a second spot.
That hose is supposed to be the hot water return and will only have a few pounds of pressure. The hose you replace it with must stand up to your coolant.

Thanks, CCAWGC.

How long do these hoses generally last? And if this one is breaking down after 9 years, should I expect my torch water hose to start leaking soon, too? (It has a nylon cover.)

Agree 100% with the suggested fix.
Timing of thread is interesting as I too had to recently replace my short return line on an older TIG cooler. Used some fiber reinforced tubing from hardware store. Viola, up and and running again in no time.

Thanks, Steveoo. Curious what type of tubing you used. Was it that clear stuff (polyethylene I think) with the white netting-like reinforcing fiber?

Without a picture, im guessing that your leak is in the middle somewhere on the hose so what about going with something like this in the size you need and in brass: https://www.mcmaster.com/5351k11 then get some of those shark bite type of connectors: https://www.mcmaster.com/52545k45 or just some regular hose clamps....

If it's on the ends of the hose i would go with something like this: https://www.arc-zone.com/Hose-Repair-Kit-A-HRG-316BR

If neither of those fixes would work then i would just get on google and look around for the brass fittings that WOULD work for your situation.

If all else fails.... just buy a new one and be done with it!

The 5200 will work, I've used it many times on low-pressure hose and tires. I just replaced a bunch of tig gas and water lines that were failing and they were all around 20 years old but these were all from miller. I doubt the imported stuff thats going around now will last that long, I think the China hose is made from our old tires.

[Kelvin]

Thanks fellas. I tried the 5200 with fabric reinforcement (applied the gook on Saturday, it takes some time to cure) and just hooked it up and tried it this morning, and no leaks.

If anyone else wants to replace this same hose in the future, I found what appears to be an equivalent – Lenco #LWH-18LH – at weldingsupply.com for about $16 +$9.50 S/H. Still fugly but a lot better than almost $50 delivered!

WeldTec/TecTorch also makes an equivalent:

but I don't know the price.

We blow hoses regularly. and sometimes swap in doubled ended hose barbs to cut out the broken section as a temp fix

[scsmith42]

Ditto the comments for a standard double ended hose barb. I use stainless steel safety wire as a clamp with them.

My factory hoses on my 2005 vintage Syncrowave 250DX lasted about 10 years before they started leaking.

[Kelvin]

Thanks guys. Looks like some double-ended hose barbs are in my future.

Hmmm...I'm knocking on the door of 10 years old with mine. When you say the hoses started leaking, do you mean also the torch water/conductor hose? And is there a way to rebuild that? (I'm not sure what would be involved in fishing the conductor through the new hose, it sounds like a nightmare.) My torch is a WeldTec TecTorch WP-20H and it's also almost 10 years old. I'm hoping I don't have to buy a whole new torch/hose assembly if/when it starts leaking...

I appreciate all the help.

Mine leaked the most from the TIG machine end. I had one leak on the torch head end which I was able to remove the connector and recrimp. As I recall (it’s been 5 years), I had leaks on the water/conductor hose as well as the high pressure hose. The high pressure hose had to be repaired about 3-4 times before I replaced it.

I repaired the water/conductor hose at the bottom by shortening it and reattaching the conductor.

Part of the problem was that the hoses near the machine were run over a couple of times after they were 8 years old. This did them in more than anything.

[Kelvin]

I gotcha. Thanks for the information.

I have used basic electrical tape on leaks with great results


...zap!

[mechanic416]

I guess I waste money cause I just replace the hose if it gets a leak in in.

Thanks, Zapster, that's surprising but good to know.

Yep, and I light my Cohibas with hundred-dollar bills, but $50 for an 18" hose is kinda steep. YMMV

[mechanic416]

You better stop wasting those 100 dollar bills and save them for a new torch.

Send me your mailing address.
I'll send you 4' of Miller new rubber with black sheath water hose, plus 2 stainless twisties to secure hose.
You can go to ARC Zone website to see how to use twisties with their set up a torch video. Then just cover each end of hose with electrical shrink sleeve.

Thanks, Estate, that's very kind of you and I appreciate your offer, but I think I've got it fixed now. If not, I'll send you an email – or may buy some cheap hose that I found on ebay – but again, thank you.

Just go to an hydraulic shop and buy some hose and replace it. Sooner or later you're going to have to buy new tires for the truck too.

Hydraulic hose? For tig water hose?

Eh?

They do have low pressure hose that is perfect for this. Many do other types of hose/tubing also.

I am wondering what the ROI is when you can buy built standard water hoses reasonably enough. This one is $14.70 with free shipping for a 25ft. length.

[Xsbank]

^that. That was my point. And for those of you who have never set foot in an hydraulic shop, they usually sell every kind of hose there.

Year and a half old thread, pretty sure he fixed it.
