I dremeled the yellow tubing to make the OD thinner, and put a coupler on, sadly its a little loose, but I e-taped it for test purposes, then I attached tubing to the other coupler, its perfect.. I have no glue or tape on it. Then at the other end of the tubing I attached a balloon with etape, I pump it the balloon gets bigger, but then the air comes out. Is it the fact that the balloon is etaped on, or something else? How can I test if the coupler works without flooding the whole thing with water? Thanks in advance.

I may be able to help, but what exactly are you trying to accomplish? I need a better explanation, you're a bit unclear.

Seeing as I am a complete noob, i'm trying to find a different way to attach tubing to the at2k without glueing the shit out of it. I tried a coupler and decided to do this test, why do you think the balloon is loosing air?

Effeminate edit : I found out that the leak is from the pump to coupler, should I fill that slace that the nub that comes out with hotglue?

Get goop, and some larger sized tubing you can stick the 2k tubing inside off, then seal it off with the goop.

My dad barely trusts me with a dremel, I have superglue and hotglue. If it is REALLY needed I can use Gorilla Glue.

Goop can be easily removed with acetone(?) when it's still mushy, and can be peeled off fairly easily when it dries, but if your state has inhalant abuse laws your going to need someone older to buy it for you.

Due to me saving up for my girlfriends Christmas gift, im going to have to use the supplies, I have. Will the hot glue method work?

No. Not really, it's not very airtight, it won't work for long if it does at all.
One tube of Goop is ~$4 at your hardware store, hardly expensive, and you'll never (almost) need more.

Blue, where is acetone sold? I've never looked for it, but it is certainly a good solvent to have.

I don't know where pure acetone is sold, but I have been using "Goof off" which has an ingredient list of Acetone, Xylene, Ethylbezene, Butyl Carbitol, Petroleum Distillates, and Toulene. Putting wet goop in this thins it quite a bit so you can get thinner layers much more easily too. I bought it at OSH.

Hot glue works :D

When you put hotglue on Krazy Glue it emits a invisable gas, and when it gets into your eyes it HURTS. You can also smell it

Yep.
Krazy glue will do some pretty Krazy things to you.
When you see the pink elephants though, its time to stop.
But seriously, you should wear eye protection when working with any form of super glue combined with hot glue.
I find that it helps a lot.

PROTIP: The hot glue is not reliable at all. Not very airtight either. Do your self an emence favor and go buy a bottle of plublers goop.

Amazing goop is most certently, Amazing. It's extremly airtight and will last forever on a 2K. Just make sure you use a libral amount.

Okay, pink elephants are bad, that mean the purple ones are good? Right?

You can find acetone in the paint section at Home Depot, maybe at Wal-mart, too but I haven't checked.
I'm not sure if it's 100%, but the can says "Acetone" on it.

Nigtfinder, if you're ever checking for leaks and you don't want to dip the whole thing in water try just rubbing really soapy where you suspect leaks, if it bubbles you know there's a leak.

Yes, the Acetone in the paint departments is 100%. However... You can also get the same stuff for a LOT less in the makeup section, intended as fake nail and polish remover. Just make sure to get the stuff that states "100% Pure Acetone". It should be available at ANY store that sells beauty products, including Target and Walmart.

I always use superglue when I use 3/8" tubing as a "coupler" for 1/4" tubing. Works a lot better than goop just because the 2 fit together so tightly (goop tend to get pushed out and will only make a seal on the outside).

As stated, goop works best.

But with your materials, get the hot glue as hot as possible, put in on the coupler and put the tubing on on top of that. Superglue it, then duct tape and e-tape it. The combination of the three lesser adhesives end up getting an okay one. Still not as good as goop.
