Carter Valve Nut/Retaining Screw/Body Threading?
 
I know this is sort of a stupid question, because I could just measure it and figure it out, but I'm just curious if anyone knows the threading on Carter's Valve Nuts? Its "wider" than a standard 18tpi vavle nut, but also appears to be around 20tpi... again just curious; I figure I might as well pick up a backup from Bacci while/if he's got one in stock.

Thanks,
Short

I think when I measured my boxgun this weekend it was around 9/16 diameter, and the threads are either 18 or 20tpi. But mine was a standard nelson threading on the nut, but the hole for the power tube is larger because carter uses a larger diameter powertube.

yeah, IIRC the ID is around .310 instead of .25; I'm about to just pull it from the gun and measure it myself; again, could've done this from the beginning, just figured I'd ask here before breaking the gun down... Thanks for the input sniper

Later version Tagmaster/Hornets and maybe trracers and mavericks use 20 tpi but I think the width is still the same.
Can you post a picture of it when you take it out? Also the valve retaining screw would likely be a standard phantom vrs for comparison.

From my experience the older pre dye carters that ive owned use the same size valve nut threading as a phantom which is 9/16 x18. But the newer carters seem to all be 5/8 x 18 . Airsoldier.com jas these two sizes. Heres a link

It's definitely an old Valve.

I just measured it and it's definitely 20tpi, and it's 5/8" diameter to the outside of the threads. ID is .320 inches!

Thanks for the link and for the input for anyone else w/ this same question Tedaut. It looks like this is definitely an older valve... hopefully Bacci's got one that will fit, and if not, eh... no biggie :) Don't really need it; just nice to have a backup in case...

Well according to what tedaut said, the newer valves are 5/8 od so this makes yours a newer valve. The older ones are the same size as phantoms.

Thanks for the info fellas, I have been curious about these dimensions too.
