Am I missing something? Can't get a seal using two jubilee clips on a 30 mm pipe. It's is one with the metal spiral in it. I even have the bendy jubilee tool thing, which is excellent BTW. Busted two clips already.

What am I doing wrong! Grrrr.
 
If a joobly clip doesn't work, it's probably because the pipe doesn't fit.
Changing to a different clip won't make it a sound job.
The pipe should seal on its own.
 
I’ve had them fail to seal only by over tightening. Jubilee clips are not precisely circular, so especially when the hose is soft you need to take care. T bolt clamps are better fitting, but they have a few downsides too.

I wonder if this is it! The pipe is old but differently fits, it is struggle to push it on to my spanking new sea cock. The others all leaked for a bit but fiddling with them worked in the end.

I'll buy some better ones suggested here. Thanks everyone.
 
Jubilee is a brand name rather than a type of clamp/clip.
The likes of toolstation hose clips are rubbish.
Chandlery ones always seem good and tighten up beautifully.

The only downside of Mikalor is that they fit a much narrower range of pipe sizes.

Not just one.
2. They are harder to fit on.
3. They are thinner, so more prone to breaking from corrosion.
4. They are much more expensive.
5. They are made with welds, which rely on very high quality control.
6. You can’t put them together to make bigger ones, as you can in big sizes of Jubilee clips.

I've had similar problems. Wire spiral pipe makes it harder to get the hose clip positioned well. Softer pipe (the material or heating it) makes it easy to overtighten and it deforms when it cools, or the clip loosens when it cools. I've had both happen to me. Recently I had to retighten over 20 jubilee clips and other brand clips on my toilet plumbing by a quarter to a full turn only 6 months after replacing all the hoses and most of the clips.

I've just replaced the conventional U-clamps on my exhaust system with Mikalors and would suggest the following:

They can be opened out like jubilee clips, hooked over the pipe and re-clamped. Mine are stainless steel so no possibility of corrosion. The welds seem fine and mine are being used to clamp metal so are are very tight.

It is true that they are more expensive and you can't string them together.

My own immediate thought! In the past I have had issues where pipe or the fittings were purchased described using 'metric' values and others using imperial values these quoted values were actually just the nearest approximation to the stated value. Consequently some connections were loose to start with.
