I'm integrating my 2k into a PAS, and I need to extend the tubing (Tried ExTenze, it didn't work D:). I went into my dads office and got some tubing that I pretty sure is 3/8th's, my question is do I have to just glue it on? Or could I use nipples and couplers? Thanks in advance.

You could use "nipples and couplers", or barbed connectors, and that would likely be best. But you can also just "glue" it in, with no likely problems. Use goop and you can put a tube directly into the AT2K tank (where it origionally was) and back onto the pump. I think there is a barbed kinda deal on the pump, you can just stick the tube over, maybe a bit of goop.

I think the size you actually want is 1/4" Vinyl tubing. It's sold at your local Lowes by the foot, at $.14/ft.

Edit: Instead of the couplers louiec3 linked below, because I'm in college and cheap, I just buy the next size of tube up, with a 1/4" ID, and goop the two tubes into the one larger one as a coupler.

If it is 1/4in OD.

If you find tubing larger than the 2k tubing, you can wrap the 2k tubing in electrical tape and goop it in.

Better than Goop would be a real adhesive. Specifically I would recommend PVC/CPVC pipe weld cement, but only if the tubing you are using is vinyl. Most of the AirTech line uses vinyl, and the clear tubing you can buy at hardware stores is too. The advantage of the pipe weld is that it actually dissolves a small layer of both sections and commingles their structures to make one permanent bond.

I feel like the OP's question has been answered, and since we're already on the topic of solvent weld, I figured it appropriate to ask this here.

When ever I see solvent weld, its always specific to a certain type of plastic. Yet a lot of people mention using a solvent weld to attach al sorts of things to each other. Does one have to figure out the types of plastic your bonding and then fit the solvent to the job? Is there some sort of magical one-solvent-works-on-all-sorts-of-plastic product?

General purpose plastic cement for ABS/PVC/CPVC should do the job for almost anything nerf-related. Standard PVC cement will also work for almost anything nerf-related. Neither of these are ideal for the job, but anything with MEK will dissolve plastic and nerf bonds aren't under that much stress anyways.

If you want to be precise about it, there are various formulations of IPS Weld-on for specific plastic: polyester, polycarbonate, etc. but I've had good enough success solvent-welding polyester to PVC and polycarbonate to PVC with standard PVC cement that I don't bother.

A barbed coupler will work fine. You can get the brass variety at ACE for around $2 per. They have most sizes. Just make sure to heat the tubing up a little before you try to slip the tubing on!
