This is the longer hose that goes from the center of the gun, where the fitting screws in to the power tube, and goes to the back of the gun to the flow control valve. Need a new hose? Why be like everyone else. Now, from TippmannParts.com, you can get this hose in cool colors instead of black. Choose your color to make a statement. Or… um… just get black. You know, like a Ninja! For the A5RT and 98RT systems you can upgrade your hoses to 1/8in ID for better air flow. While Tippmann Sports says this isn't necessary, many players are now doing it. This is the 1/16in ID version. 1/8in ID version is TA05018. Note: The colored hoses are cut slightly long. You can cut them with a razor blade to the exact length you need. These hoses might have specification numbers in contrasting colors. When installing, face lettering towards marker for solid color consistency.
