Air con pipe repair

[grass man]

Just had a rubber pipe rubbed through on a fan belt. There is loads of excess pipe, was just thinking can it b cut and repaired with crimp on hyd fittings or is there any other methods to repair these. Tia

Or is a simple push in ribbed air line fitting or something similar with a few jubilee clips sufficient

Worth a try but I was told rightly or wrongly hyd fittings aren’t up to it same goes for an air line fitting I guess. If you’ve lost all the gas from the system then the cost of refilling to then have it leak again I’d be pricing a new pipe. That’s my opinion anyway

 

[Lincsman]

Buy a new pipe.

Plus one for new pipe

Had one fixed by hydraulic man.
Dominator 78. Pipe had been left unhooked and exhaust burnt it through. Worked fine for about 5 years before combine was sold.

With the price of a callout and the price of gas, i would be inclined to get a new proper pipe fitted, rather than a bodge that would probably let go at the most inconvinient time, saving a few pennies usually cost a few pounds in the long run.

why is that the pressure on the air conditioning should be around 30 psi or is this another manufactures rumour to avoid lost sales ?

A mate bodged the air con in his spfh with a hydraulic hose with crimped fittings, an hour in the field, and the fitting has lost all the gas, so he was back in his underpants sweating his nuts off, £250 lighter

What do you mean ?

I’m not sure tbh prob as it doesn’t matter with air if you have a small leak

That's what I was getting at. If an airline fitting can easily hold in air with a push in fitting and a jubilee clip, why would it not be up to an air con pipe. I'm not trying to avoid the cost of the pipe just the time associated with removal, ordering and refitting when there is a lot of slack where the leak is and 5 mins would bodge/fix it. Anyone know the operating pressure of a vehicle air con system?

Repaired one last year with hydraulic repair man. Still working a treat. First repair shop said no cant be done. €20 fixed it. I think jd wanted around €350 for said pipe

Because how do you know the air line isnt losing a cupful of air every year, like say a tyre, in an air con system half a cupful lost and it wont work, and I am not sure if air con gas has smaller atoms or something?

Even the "O" rings in air con pipe fittings can't be standard "O" rings! the gas must do something/react to bog standard rubber?

Just don't okay. A bodged repair could easily burst with you in front of it. R134A boils at minus 26c. If it were anywhere nr the evaporator in the cab it would instantly mist the windows.

A resting system could be upto 100psi, a working one on a hot day 250psi on the high side.

Gas is now almost 3 times thge price it was 18months ago, so fix it properly and dont bugger around. AMA or APair will re-make your existing pipe, you dont need a costly dealer part necessarily.

They're not standard neoprene no.
