The Rusco AFV-KIT Flush Kit For The Automatic Flush Valve is a wonderful device that includes 2) 1/2" Barb x 1/2" NPT male hose fittings. It also includes two SAE size 8 SS worm drive clamps and a 24" long braided reinforced flexible 1/2" PVC tubing. All these devices work well in smooth installation of the automatic flush valve. It also reduces the hassle of making hardware store runs. This kit does not include the Rusco filter housing and automatic flush valve.
