3/4" Od Pvc?

They do manufacture plastic tube out of PVC plastic, so you can buy 3/4" PVC tube which will have 3/4" OD. But then the ID isn't related by any pressure standards to the OD or wall so unless an ID is specified it is unlikely that the instructions call for plastic tube as opposed to plastic pipe.

Honestly, seeing the guide will help.

3/4" PVC Pipe - PVC pipe is a plastic pipe that is used in plumbing. It's light weight and easy to work with and make the structure of the boffer weapon. You can buy it at any large hardware store such as Home Depot, HQ, or Builder's Square. You'll need three-quarter inch (3/4") pipe. A 10 foot pipe costs about $2.00. There are three different types of this pipe. One is white with blue lettering, one is white with pink lettering, and the other is gray with black lettering. You will want to buy either the white with blue or pink lettering pipe because the gray pipe isn't sturdy enough.
This is taken from the guide. I get the feeling the tubing you're referring to isn't particularly commonplace. The ID isn't important here, so long as the wall thickness is not so thin that the pipe/tubing has no structural strength/rigidity.

If he is actualy talking about 3/4" pvc pipe, then see the post above mine. This would indicate to me that the person who put together this guide really doesn't know what he is talking about, and, therefore, may be full of crap on the entire thing.

Why the hell are you asking us then? Ask the dumb ass that wrote such a poorly constructed guide.
the guide I'm following calls for (quote) 3/4" PVC pipe (/quote) to fit into a 3/4" hole.

CS, you do have a point, and I can try and find a way to contact the guy. Judging by the way he wrote this though I get the impression he probably doesn't know the answer to this himself.

Alright, but the holes in what I have do appear to be exactly 3/4". And he says that it should be a pretty snug fit, which is why I've been trying to find out what might be out there that has a 3/4" OD. I can try to bring in a piece to Home Depot or whatever, but I'm afraid that what I'll find is that nothing there is going to fit. It shouldn't be loose at all.
Assuming this is for a boffer-
If your tube is a little bit loose, wind a few layers of duct tape, in a few places on the tube (no need to cover the whole thing). If the gap is small, you can easily fill it (to whatever tightness desired) without wasting much time or tape.

Also, I'm assuming you're asking because you're putting 3/4" foam over the pipe? Don't worry -- the foam may be a little tight, but it will fit over the pipe just fine.

I'm not too sure about this stuff's ability to stretch to accommodate it, but I'll see what happens when I try to shove a piece of 1/2" PVC into it next time I go to the hardware store.

I just got a response from the gentleman who wrote the guide, and he gave me every bit of information I asked for and then some.
I've pulled out some of my materials to get exact measurements.
The pool noodles I have have an exact 3/4" interior diameter.
The PVC I'm using, which fits snugly into it is labeled as 1/2". I
have two types of PVC, both the same size, that are different
thicknesses. Here are the exact measurements and labels:
1/2" Cresline: Inside: 11/16", Outside: 7/8"
Label: PVC SDR 13.5 - 315 PSI PR Water At 73 F PVC 1120 NSF-pw ASTM D2241 PPFA
This PVC has a pink label and is very light and sturdy.
1/2" Bristolpipe: Inside: 5/7", Outside: 7/8"
Label: PVC 1120 SCH 40 ASTM D-1785 NSF-pw 600 PSI 73 F BP-2 L PC
This PVC has a blue label and is a little heavier than the pink labeled PVC.
So yeah, I guess my measurements are a little off, I'll have to update my site.
So that clears that up. Looks like 1/2" PVC it is. I'll fill him in on what I can.
