but yeah so can anyone answer my question post above^^ on the teflon tape type??

They both work, just use a lot.

yeah okay, when i screwed them on, i would only get the thread in like 3 rotations, thats prolly not enough right??

The gas variety is indeed the thicker yellow-ish type, and contrary to what mopherman says, there is an important difference.

Also, don't expect more than about 1100 fps from air, regardless of the pressure or valve. GGDT gives some pretty odd results around the sound barrier.

I never said there wasn't a difference, just that they both work. What is this important difference you speak of anyway?

[Ragnarok]

@mopherman: I've used both, and I always get less leaks with the gas variety.

[cwazy1]

hmm, maybe i'll have to go get some more of that stuff. . . . i went and bought a bottle of pipe paste, i'll see how that works out.

[cwazy1]

ok so i fixed all the leaks and its good now, ...heres a pic of it with a qev

sorry about bumping this almost dead topic but i have a question about the valve, how did you fit it in the tee and have good travel because i noticed you have a threaded fitting straight into the tee so i'm confused about how you fit it in with good travel

thanks Alasdair.

It's a threaded tee, that's it..

yes but i'm wondering how much space is left for piston travel when the threaded reducer is in the tee?

[DYI]

Well, the barrel is .5", so the piston should travel anywhere between .25" and .5". There seems to be ample room for travel.

ok i see to have got t into my head that pistons need to travel miles to be effective despite knowing that they only need 1/4 of the bore :happy8:

[cwazy1]

lol yeah theres like .5" of travel inside the tee.

if anyone is interested, heres an updated picture.
