if i am using 1/2" valves what size airline do i need for the best performance? 1/2" actually refers to the line hook up right? not the size of the orifice that lets air into the bag.or do i haveit wrong

With a 1/2" valve. Running DOT Nylon Airbrake line.
You need 5/8" OD tubing. Or 3/4" since its quite a bit easier to get.

This is for DOT AirBrake line. What is recommended and used in general.
1/2" valves, use 5/8" or 3/4" line
3/8" valves run 1/2" line
1/4" valves run 3/8" line

I got confused too. Keep an eye on the posts for updates!

It looks like maybe 5/8" line for 1/2" valves is the best.

ok heres how it goes

5/8od = 1/2 id
1/2od = 3/8 id
1/4od = 1/8id


now i run 1/2 line with my 1/2 line with no problems of being any type of slow/ you can use either 5/8 or 1/2.. just depends on how high you wanna hop. and also psi rating is a factor. if your gonna run comps i would run 1/2 if your gonna run n2 i would run 5/8.. also i run n2 at 225 psi and i launch off about 3- 4inchs
