Hunter Eco-Indicator 12 in.

The Hunter Eco-Indicator Black, Yellow Npt 1/2 in. helps confirm system operation and adequate pressure. Once the pressure exceeds the threshold, the riser will pop up displaying a bright yellow or reclaimed purple stem. This commercial grade body attaches to either polyethylene or PVC through a 1/2 in. NPT connection thus avoiding 1/4 in. tubing. This adds durability to the system that no other indicator can boast. When the system is not active, the indicator will be in its retracted state and be flushed to the ground.
