Filling a closed loop system with heat transfer fluid is easy with this fill valve. It allows you to flush the fluid through the loop continuously using the included drill pump. The continuous flush assures that no pockets of air remain in the system. No air means that your system will run at peak efficiency and the glycol will last longer. With this filling your closed loop system properly only takes a few minutes.
