MIG gas leak

[Speedy Builder5Participant @speedybuilder5]

My MIG set is about 10 years old, and I use disposable bottles of CO2/Argon mix bottles.  Whilst using the set today, I just happened to hear a hiss above the drone of the radio.  Finally located it to the flexible gas pipe between bottle and torch at a union inside the machine.  The tube never had any pipe clips as bought and I assumed that as the line pressure would be low, not required – WRONG.  I have now made some wire “clips” to seal the pipe to the union(s).

I’ve had a CO2 regulator fail, just check it’s not leaking on the diaphragm as well.

As the set is ten years old might the pipe material have lost elasticity and relaxed slightly away from the fitting?

If so it might give a similar problem at the nozzle end too.
