1/4 would probably be better if using teflon tape
the fine threads of 1/8 can easily get stripped in the pvc right
i'll go with the 1/4
thanks for the input

yes, i can get either fine 1/8 or course 1/4 as far as holding power i was wondering if there was a differnce
i would hate to launch the fittings instead of a projectile
