These hoses are standard 1/8th inch npt  threaded hoses that work with most paintball guns.  Great for use with CO2 or Nitrogen! 
 
Stainless steel fittings and stainless steel braided hose are without a doubt the toughest lines in paintball. Perfect for rough slides into the 50, and perfect for rushing through thick brush. While it's not as easy as macroline to install on your paintball gun, you'll only have to do it once. Set it and forget it.

 you can link them up with any standard female 1/8 npt  port or fitting. Be sure to allow an extra inch so that you don't end up with too short of a hose. Unlike macroline, you can't cut the Stainless Steel braided hose to fit your paintball gun.
