Zurn AG-9 Air Gap Fitting

The Zurn Wilkins AG-9 is a genuine air gap fitting for 4" to 6" Model 475V.

The AG-9 Air Gap Fitting is used for indoor installations of all 4" - 6" Model 475V 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 iron inlet with elbow and 3" NPT 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.

Common Questions

Will this kit fit my assembly?

The AG-9 fits 4" and 6" sizes of Model 475V. Kits are size- and series-specific, so match the model stamped on your valve body or cover before ordering.

What's included in this kit?

This is a air gap fitting -- it carries the factory parts for that subassembly only, not a whole-assembly rebuild.

Are these genuine Zurn Wilkins parts?

Yes. This is the factory AG-9 kit built with genuine Zurn Wilkins OEM components. Aftermarket parts can void your assembly approval and are commonly rejected by inspectors at annual test time.
