Hey again, alright I'm up to the part of attaching the blow gun onto my air tank for my vortex BBMG, but i got one problem... attaching the elbow to the blow gun isn't a easy task as i thought it would be...

What i was planning to do is to get a smaller tube thats small enough to fit the blow gun and elbow tube's hole and epoxy it to gether, but I don't have any O ring's that will perfectly fit both internal tubes, so yeah i was wondering if plumber's tape will help seal off any air leaks... this is the progress of my guns so far...

you can see a tube connected to the blow gun... it's not glued in just to give you guys an idea what i was doing.. i've pumped it to 10psi and squeeze the blow gun trigger and yes it releases air finely, i charge it up to 15 and obviously the tube couldn't hold on and the tube blew off

Don't start crying when I play this as my hobby, Paintball, Airsoft and Nerf are equally good hobbies, except you can play Nerf in public. Good day! Hmph!

get a new cap and install a pop in shrader valve.
Remove the core of the valve and install an elbow onto the shrader(which is 1/8" NPT threads)

I'll probably think about doing that after I make another duplicate of the gun, but I just wanted to know if plumber's tape can act like an O-Ring.

The gun I'm making now is only a prototype but I'm going to try to make it as flash as I can.

And wouldn't do that reduce the air flow from air tank to blowgun?

It will probably work if you make sure it is wrapped TIGHT. And I do mean tight.
Stupid quote of the now:
joestue "The chamber is rated to 100 psi, it don't say that on the side, but the 2 inch stuff is rated to 300, so by analogy..."
"only the last two feet hear the end is black cellular core"
"I'm taking it to 300 psi"

Reduce flow...blowgun...blowgun chokes flow already

If you are meaning PTFE (teflon) tape, this does not seal, it just lubricates.

Err so what kind of tape should I use to seal my tube up because I got this far, and I kinda not want to change what i've got because I got a week left of holidays so I just want to keep it simple, sure making a vortex will be troublesome, but i just need somethign to connect up to my blow gun, and this is the idea i thought up on the spot with the materials I have on hand.

Anyway what kind of tape should I use then?

Well the tape will defiantly NOT work. I don't know how you could make an Oring help you either. If you insist on using a Soda Bottle (you should make a proper tank) then you should really go with Frank said. Its the only way to get a good seal with you;re current configuration.

The way you have it right now will leak. blowguns only seal correctly if the 1/4 inch side is connected to your air source. That is the way a blowguns poppet(?) valve is made.
