Can anyone recommend a good (possibly epoxy) thing to patch an Evakool/Techni-ice style esky with?

I'm building a dual purpose coil chiller - mostly it will prechill the water before it goes into my plate chiller, but will also serve as a jockey box on camping trips.

Anyways the stainless coil i've got has threads welded on the ends and one of them is not quite long enough to act as a bulkhead type arrangement, so i'll have to push it through the wall of esky and patch on the inside.

I'm thinking Selley's Knead-it - but that is very exxy and I may need a sizeable amount.

Any other suggestions for a waterproof epoxy type putty?
 
as alot of these plastics are non adhesive, and will sometimes only bond to like materials it might be a case of trial and error, you maybe lucky and someone else here has done the same thing.
 
it will not stick to the plastice you will only get a macanicale bond so ruff up the surface and use a two pack epoxy with some filler such as micro bolloens

Yep - I agree with this - I patched my esky mashtun at the outlet a few months ago.
The inner lining where the bulkhead exits had started to delaminate and split due to 3 years of (ab)use at mash temps and the mechanical stress of the tightened bulkhead.
I kept the hole openening clear with a bit of dowel wrapped in glad wrap and then bogged it up with Araldite. I roughed the surface up a bit with some 80 grit sandpaper. It hasn't budged in the 6 brews since and provides a better seal than before.

does this translate to araldite?

do you mean micro balloons? Mr Google doesnt compute with micro bolleons?
 
ya on the micro balloons and na on the araldite 2 pack fiberglass resign
 
hmmm.. thinking now maybe i connect threads i've got to a longer piece of thread to create a true bulkhead arrangement.. sounds like sticking to these eskies/plastics is harder than i thought it would be. also if i use a real bulkhead type hole, i can plug it no probs in future if required.

back to the drawing board!

If you can do it that way it would probably save a lot of hassle
 
Regarding epoxy in mash tuns

Be aware that many epoxies are not rated for food contact
 
Just use a socket and screw a longer length of thread into the other end.

that's my favourite idea, but the threads i've got are 5/8 BSP, finding general fittings in brass or stainless in 5/8 is pretty hard, all i can find are bright steel (aka rusty)
 
Go to a general engineering shop that sells bearings and bolts and stuff. They'll have it or be able to get it in brass or staino.
