Zurn AG-4 Air Gap Fitting

The Zurn Wilkins AG-4 is a genuine air gap fitting for 3/4" to 1" Model 975XL / 975XL2.

The AG-4 Air Gap Fitting is used for indoor installations of all 3/4" - 1" Model 975XL/975XL2 Reduced Pressure Principle Backflow Preventers for the connection of a drain pipe to the backflow preventer, directing nuisance water discharge to a safe drain.

Common Questions

Will this kit fit my assembly?

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?
