Wilkins AG-4 Air Gap

The AG-12 Air Gap Fitting is used for indoor installations of all 1-1/4 inch – 2 inch Model 375/375XL Reduced Pressure Principle Backflow Preventers for the connection of a drain pipe to the backflow preventer, directing nuisance water discharge to a safe drain. It has composite inlet and 3 inch IPS slip outlet connections. The AG Air Gap Fitting can be mounted to the body of any drain line made of any standard piping material. The AG prevents a cross connection between the drain and potable water supply. Materials include an epoxy-painted cast grey iron elbow and zinc-plated steel bolts for long-lasting effectiveness.
