Macroline is quickly becoming the most popular gas line in paintball, due to ease of installation. Once you install the fittings in your paintball gun, you simply pop one end of the hose in each fitting, and you're set.
This package contains two 90 degree macroline fittings. The threads already have sealant on them, so there is no need to use teflon tape or threadlocker to prevent leaks. Simply screw them into your paintball gun, torque them down, and install the macroline hose (sold separately)
