Where can I get a rubber expansion plug !

Ok....not quite as dodgy as it sounds....

But this sort of thing,

I want to make an airtight seal in a plastic air intake, after I have removed a 1/2" vent pipe to do a mod on my Jeep...this a well worn American Mod, and the part above is on American Ebay....is cheap, but postage is £20....never seen anything like it before, perfect for what I need....anyone know what if it goes by another name over here, or knows if something similar ?

Thank you

Either of these any good?

I don't think so as they need to be air tight...the first is on the right lines, but appears to have a hole for a cable running through it...the second would need to be an exact push fit, and then be secured somehow.

I might have found a plumbing solution....rubber bung to go on the outside with a jubilee clip to hold it. I need to go and measure....but the American version is perfect....maybe I've found a new business opportunity as a Bung importer !

Thanks

Looks like a rubber sleeve or bush with a bolt through it. Can you find a short piece of rubber hose or bush the right size and put a bolt through it?

Is this going to have positive or negative pressure behind it and if so how much?

[phillpot]

I'd presumed negative as it'a an intake manifold, unless it's got forced induction?

Yes, well found. I actually came up with this...http://www.ebay.co.uk/itm/PLUMBING-FLEXI-PIPE-FITTING-STOP-END-CAP-CONNECTOR-JUBILEE-CLIP-All-Sizes-/251170227476?var=&hash=item3a7ae98514:m:mtpTIViDdYmqNYNNPcdGgzw

I'm trying to do this mod....

I am planning slightly different, hose routing, and maybe a catch can....but you get the idea, and the use of the bung. I have seen the mod done with mastic, silicon sealant etc....but I'd like the reversible version !

Make damn sure there's no way for anything to come loose on the inside.

Getting closer, but not cheaper! .... clicky
