Mopar Muscle Association UK

Title says it. Whatever name you know them by, I want to use them on my trans cooler since they are nice and clean, less obtrusive than jubilee clips (yes I would have preferred AN fittings but I am where I am).

Either convince me this is a bad idea (pressure, leakage?), or help me out with where I can order up a few over the web!

Thanks

Check the ebay

or plant hire places.

you will hate those clamps if you ever need to get them off

I'm with Will.... horrible things

Long thin screwdriver in the "pinch bit" and twist, that usually does the trick to get 'em off and a pair of carpenter's pincers to clamp 'em back up again.

But I'm with the two Wil(l)s, they're horrible things.

any company that does hydraulic and pneumatic hozes should be able to help, im sure my local one does. if you cant find any let me know and i will pop in the place i use (http://www.leighbaxter.co.uk/products.php ) in southend and ask the question.

Gavin - a length of gardener's twine with a double knot should do it...

Just kiddin!

Go with the ones Will posted - they look way smarter than jubilee, and you can easily judge the 'pressure' required, unlike the ones you show.

Thanks so far....
I've never really considered them, but then I thought - why not! In theory they should be better than a jubilee, the springiness of the clamp holds them on and not the pressure generated by the worm drive etc, so they should stand heat cycles better etc.
Still, I've never had any issues with jubilee clip performance, they just look a bit gadge!

These are simple, reliable, quicker than a jubilee to fit, ought be cheaper (though not an issue with the small number I need), but mainly should just be very unobtrusive - especially behind the grill where I don't minimal or no shine (I'm even plating the cooler lines black!). The factory used them so they should last for ever.
I agree - they more difficult to remove but I'm not planning on removing them often, and it's not that difficult - could even cut em off with a dremel.
I like the ones Wil showed for some applications but they have the same issue as jubilee clips in this case for me - bulky and ugly. Phil, I reckon with minimal practice these should be as easy to judge the tightness as a jubilee clip. I'd experiment a bit to get used to crimping them, but you can usually judge from the hose starting to bulge

So, concensus is people don't like 'em - but none of the reasons so far would be an issue for me in this case!

Anyway, I found some more on eBay - thanks for suggestion latil, those other ones were too big, but I found some other vendors. I also learnt 2 more names for them - Ear clamps, and O clips. How many different names can the same clip have for goodness sake!!!
If I can't find any that are black (unlikely) I'll likely get some of the ebay ones - if not I'll be in touch Trev, thanks for offer!

Then all I'll need is a blunt old pair of pincers....

main reason I don't like them is they don't clamp the hose all the way round, the ears parts barely touch. I don't like Jubilee (worm drive) clamps either, but I do rate clamps that go more than 360° round, like wire ones.

We use these, or ones very similar. The ones we use have an additional ring on the inside which solves the problem will mentions.

I think they are great, and for where it matters, very neat.

Our normal use is on fuel hoses on the pressure side on modern cars, normally 60-70psi. Wouldn't dream of using a jubilee clip in this application. The ones with the inner ring we get from Wurth, but you will need to buy a whole box

Thanks Roger, I did a bit more digging and found a number of places I can get just a few. But it's pretty clear that they are widely used in a number of industires (not just automotive, but hydraulic as Trev said, for water pipes, compressed air etc). That's good info about the high pressure fuel, that is a safety critical application. Also as you say there are variants that have a complete circle.

Here is a good reference point I unearthed, which confirms most of what I expected and also shows how they should be properly installed, thus avoiding this issue Wil mentioned as well:
http://www.zeroclips.com/o_clips.htm
e.g.

Jubilee themselves also do O clips, useful PDF here http://www.jubileeclips.co.uk/pdfs/Lit% ... 0Clips.pdf
again makes the point that the gap at the ear should not be fully closed (1.5mm gap) as this actually ensures a spring action to provide good clamping. Also addresses removal etc

You can also get them in stainless but don't think anyone does them in black, never mind I can fix that.
My only question now is whether I should get a kit of multiple sizes cos I think I'll be using more of these! Like I said - they are not exactly new, they were used on our Mopars originally, but I never gave them a second thought. Now I have!

Very interesting thread, this.

You do really need the right tool for installing these,of course there's one for each size of clip.

Are you sure that is for O clips Steve?

I have looked at quite a lot of sources now and without fail they all show this lind of tool, which is universal (one size for all clips).


Even the manufacturers (Jubilee in this case) show that same tool
http://www.jubileeclips.co.uk/products- ... ncers.aspx

That is off US ebay sold as an Oetiker clamp installing tool.
