#2 Rubber Bung.

[Greg2013]

I ma going to give a lash at building my own cheap bottle filler but i need a rubber bung that will stopper the neck of a coopers pet bottle, apparently these are #2 ? Not sure what exact dimensions this is, i know Shane had a look and unfortunately HBC don't have one this size so i suspect they may not be easy to come by.

I am not going to pair one down, i couldn't be arsed TBH. Preferrably a bung thats pre drilled to take a bottle wand, i think its 3/8" ?

I made my own from a bottling wand & pared down rubber bung. It was total shit haha. Ended up buying one of these instead:

I also bought the little attachment that fits inside my perlick tap. Works brilliantly. I give my bottles a squirt of c02 first before filling. The bungs are very soft so are easy squeeze to release the pressure inside the bottle. Then cap on foam.

What are the little red seals in that for ? That's basically the setup i was going to build, looks like i would have had to order the bung from USA anyway so that might be a better job? Also i dont have a perlick tap lol.

The rubber seals are spares for the nipple attachment for perlick taps. Pretty sure you could just squeeze that tubing onto a piece of the bottling wand & then stick that into a piece of silicone tubing & slide it over your tap.

Did you get that attachment from MoreBeer.com or somewhere else?

Thing is i have a bottling wand already, i have the tubing i think, i really only need a drilled #2 bung tbh, just don't know where to get one.

Get a wine cork and drill it. Cheapest, quickest option.

I got a bung off eBay for mine. I'll dig out a link later if I still have it, if not I may have bought a spare though not sure. I'll get back to you.

The one I used was actually a no. 17.  I just tested my filler in a coopers plastic bottle and it almost slips inside, so a no.19 may be better for them.  King scientific have them on ebay and amazon:

search their stuff for "bung" to see the various sizes.  I think the measurements are bottom width, top width, height.  Coopers bottles have a wider neck than glass, but a 19 should be fine for both.
