Oatey Sure-Vent AAV Wall Box – Recessed Air Admittance Valve Housing (4.5 x 5.75 in)

Compact, recessed solution for modern plumbing ventilation

The Oatey Sure-Vent AAV Wall Box is designed to disappear neatly into walls, providing a recessed home for air admittance valves when a flush, professional look is desired. It's ideal for installations where the AAV must be hidden behind drywall, tile, or other wall finishes while still offering easy access for service or replacement.

Built to endure everyday use, this wall box uses high-impact polystyrene to stand up to typical bathroom and kitchen environments. It can accommodate 6 DFU or 20 DFU Air Admittance Valves with adapters sized 1-1/2 in or 2 in, giving you flexible fitment for a range of AAV models. The textured grille faceplate helps conceal the valve and provides a clean, finished appearance without visible hardware.
