go with 3/8", you will probably end up reducing them anyways.

my 3/8"valves dumped mad fast..i ended up getting some plugs and drilling a small hole in them to slow them down...if you dont want to run any bigger than 1/2" lines then just get all 3/8" valves..the inner diameter of 1/2" line is 3/8"..1/2" fill valves on 1/2" line wont be any faster..

1/4 inch valves for 3/8 air line 3/8 valves for 1/2 air line and 1/2 inch valves for 5/8 air line you save money and maxamize the flow threw the fittings this way. any thing you need let me know and ill help you out.

thats a waste of money if your gona run 3/8 dumps and half inch fills run 5/8 air line if your only gona run 1/2 air line save you money and buy all 3/8 valves the smallest hole will limet your air system which is the inside of the air line.

well considering airline is $.60 a foot and i only used 25 feet... I can afford to chunk $20 until I get fully bagged all around.

Besides those fill valves are BORROWED valves.

dude! lol

yea air line dont cost that much im just saying for people buying kits that dont know about air flow. the valves them selves are cheeper and you should maximize the flow for you money. i just mention this because people allways want to order 1/2 air valves and air line and i tell them you can save money on valves and fittings by keeping the 1/2 air line and going with 3/8 valves and fittings with 1/2 tube. i was just replying to the thread starters post tryin to help him out.
