Er, well, no. Actually, that's the point. They don't, and is why manufacturers dont use them on the cooling system.

Like Nick and others I was slightly skeptical at Marks comments all those years ago. But he's absolutely right. As usual.

Expansion and contraction of rubber hose over thousands of heat cycles under a fixed diameter fitting means the jubilee will, eventually, leak by. Especially by the worm gear.

Just does. Presume Kevs issue is similar.

Nah, cobblers.  Manufacturers dont use them because it takes time to tighten them up.

Remember, everything is pretty much assembled before the engine marries the car.  Then look at the heater hoses - they are push fit with a locking tab.  Why? because they are fitted after the engine has been mounted. Quick and easy (although expensive).

It's got bugger all to do with reliability... It's all to do with cost of production, including the time to fit.

Again, fit an LPG kit with the supplied jubilees. Then we can talk.

I replaced several a couple of weeks ago, as whoever installed the kit (bearing in mind it was a few years ago) used the wrong size.  I had a coolant 'weep' from the vaporisor.  Pipes off, new Jubilee's (in the correct sorta size) and cushty.

No pissing about with clips which 'ping' all over the place.  Don't get me wrong, there is nowt bad about them, I just like to know something is tightened to MY specification, and not that of a supplier who doesn't know the application it's being used for.

Clips are a pain to use , but give it time and the jubilees WILL leak. Mine leaked after a year or two. As have Kevin's by the sound of it I guess? And aTB had similar on his.

The fact the clip was the wrong size means little more than poor fitting.

Avoid the cheep Chinese ones on offer or any of the gold coloured ones.
Tried quite a few and pretty much all are crap with little or no tension after a few months or even friggin days 

I settled on the Mikalor brand for all my LPG / Water pipes and not had a problem since
