The Flex Connect is a large bore line for your PolarStar that is both flexible and durable. It is made from the same Big Bore Braided line as we use on our Firebase remote air systems. Available in Black, Brown and Digital Camo, the Flex Connect improves both the look and usability of your PolarStar. The Flex Connect installs easily onto the existing macro line on your Fusion Engine. It replaces the portion of the macro line line where it exits your grip. It is more flexible than the standard macro line and eliminates the crimping you can get with macro line. To install this product, you must cut your existing macro line closer to your Fusion Engine, and use a 1/2 inch drill bit to enlarge the hole in the grip plate or remove the grip plate entirely. Max pressure for this line is 200 PSI.
