FEBCO 905345 RV RUBBER 860/880 1/2" - 1"

genuine product

good shipping, genuine product. It's hard to find these items locally as you generally have to have a trade account to purchase them at the irrigation and plumbing supply centers. I *got* to purchase this twice by my own error, so be sure to pay attention when repairing the backflow. There's several videos available to explain how to to do it, watch them several times and carefully. The first time I tried, I had some stuff backwards and pinched, and unfortunately I had to replace it again.
