What tap is used for paintball-gun fittings??

[FrAuStY]

PLEASE HELP... ANYONE!?!
Does anyone know what the thread standard is for paintball gun fittings? I'm have to tap a new hole for a fitting on my foregrip and I couldn't find one at my friends house. (His dad owns like 100 taps) and none of them match the thread/diameter for the fitting. Is this like some conspiracy amongst the paintball gun manufacturers and the machine shops? People can no longer fix their own equipment, they'd have to send it to a shop? Can anyone help me? AGD/GOD could you help me? I know AGD knows the tap size... hopefully they would be kind enough to share it with me If I can just buy that one tap, it can be a life-saver if you accidentally strip something at the field

Pl... pla.....plaassee.... plaa..ees hal....hal..p (LeLu on 5th Element in back of cab..begging for help.. thats me right now!!)

1/8 NPT is used for air fittings.

If you mean screws, then it doesn't *really* matter as long as they fit.

I need to know the thread pitch and diameter. I did notice most fittings are tapered on one end.. Not sure with the pitch is.. who knows.. I may have fubar'd my foregrip if so.. oops. Its non functional anyway until I can tap threads for a 90 coming out the side FRICK FRACK BIZKBAGAFRAGARAT

Well, 1/8 is the diameter, and NPT stands for National Pipe Taper wich is a standard for threading.

If they have all the taps they should be able to tap it with that.

It's not 1/8 inch.. That would be like the diameter of macroline prolly smaller. Geeze.. I knew it was a conspiracy against the paintball players.. AGD could you please help me?? PLLLEEEAAASSEEE??? I appreciate all input from you guys..

NPT stands for National Pipe Threads

It is 1/8th inch!

Yes...It is 1/8 NPT for most fittings.

[FrAuStY]

So you're saying I could go down to the ole sears store... go into tool territory (only the largest selection of craftsman tools in the universe!) and asked for a 1/8 NPT tap...and he should bring it..and it would be the right one? Grr.. as I've said before its all a conspiracy ... <SIGH>

[Tunaman]

Yes...you can find it at sears

Pipe Tap!

Just get an 1/8th pipe tap! All these guys are correct!

[MikeCouves]

Yeah everyone else is right lol, it's 1/8". Some people just don't listen.

Actually 1/8" npt is no where near 1/8". It is tapered. And your friends fathers tap set is not likely to have it. As people have pointed out here.
I don't have a Machinists Handbook handy to give you the numbers. Not that that would be helpfull. There is a huge tolerance range for NPT threads.
It is not a conspiracy paintball people, it's an anchient conspiracy of pipe fitters going back to 1882. It really makes little sense.
Hopefully, you havn't bunged it so much that there is no meat left to tap and get a decent seal.

Pipe thread sizes do NOT refer to ANY physical dimensions. They're just numbers for quick reference. The 1/8" NPT is actually 0.405" O.D.

Most people here know what they are talking about. I answered your e-mail the day before and you refused to believe me and come here to ask people and they tell you the same thing. If half a dozen people tell you the same thing, don't you think you should take their word for it or at least do a quick search on the internet about National Pipe Thread sizes?

[FrAuStY]

Actually I haven't had a computer to reply since my last post. It wasn't that I didn't believe people, and Black yes I did go check it out..without you having to tell me. I didn't know that the "conspiracy" went back to 1882 LOL. I want to thank people for responding and the reason I said it wasn't 1/8" was because it isn't.. Any way.. I got the right tap at sears and tapped it. Only problem.. the teflon keeps tearing (in the grooves of the foregrip) I guess more money gets thrown into ol paintball gun. But thank you everyone.. I now have a tap for my paintball gun. Peace.

P.S. it didn't take 12 people to tell me.. it only took 2

Try wrapping the tape the opposite direction that you are applying it.
Next you could pick up from Sears or Home depot some pipe thread sealant. Non-permanent is a definite must.
With regards to numbers. I used to think the 1/8" "referenced" the nominal internal diameter of the pipe. I have never had any luck confirming that. Pipes don't make any sense either!
Good luck dude!
