Sioux Chief 696-11 OxBox Turbovent PVC Air Admittance Valve Adapter

The Sioux Chief 696-11 OxBox Turbovent Air Admittance Valve (AAV) Adapter is a PVC fitting that lets a plumber terminate a vent line without running a full vent stack to the roof. The family is available in 1-1/2" and 2" PVC adapter sizes to match the DWV piping on the job, and both sizes share the same OxBox housing format for a clean behind-the-wall or under-floor rough-in. The Turbovent AAV opens at just .01 inch of negative pressure to admit air into the drain-waste-vent system and holds a positive seal against back pressure up to 13 psig, regardless of which size is selected. It is built for fixtures such as island sinks, remote lavatories, and other traps where extending a vent stack to the roof is impractical, and it ties directly into PVC DWV piping using a solvent-weld PVC adapter body.

Key Features

  • Trade Size Range: Offered in 1-1/2" and 2" PVC adapter connections for direct tie-in to matching PVC vent piping in the DWV system.
  • PVC Construction: Solvent-weld PVC adapter body built for behind-the-wall or under-floor vent line rough-in, shared across both sizes.
  • Quick-Opening AAV: The Turbovent air admittance valve opens at just .01 inch of negative pressure to relieve vacuum in the vent system as fixtures drain.
  • Positive Seal: Holds a positive seal against up to 13 psig of back pressure so sewer gas stays out of the occupied space.
  • Self-Cleaning Actuator: The internal actuating device spins each time the valve activates, keeping the sealing surface free of dust and debris for consistent long-term operation.
  • Thread Sealing: Seal threads with PTFE tape only - do not use pipe dope - per the manufacturer's installation instructions.
  • Installation Orientation: Install upright and vertically, and in an accessible location only, per manufacturer requirements.

Technical Specifications

  • Country of Origin: United States
  • Packaging: 6 EA per case
  • Connection: Threaded, sealed with PTFE tape (no pipe dope)
  • Adapter Size Range: 1-1/2" and 2" PVC

Typical Applications

  • Island Sink and Remote Fixture Venting Without Roof Access
  • Renovation Projects Where Extending a Vent Stack to the Roof Is Impractical
  • Residential and Commercial Rough-In DWV Plumbing
  • Remote Lavatories and Traps Requiring a Local Vent Termination Point
  • Accessible Chase, Cabinet, or Wall Cavity Installations Per Manufacturer Requirements

Why Sioux Chief?

Sioux Chief backs the OxBox Turbovent adapter with a PVC body manufactured in the United States and a self-cleaning actuator design that keeps the AAV seal free of debris between cycles. The .01 inch quick-opening response and the 13 psig positive seal give installers a documented performance baseline for accessible-location vent termination, consistent whether the 1-1/2" or 2" size is selected, and the PTFE-tape-only sealing requirement keeps the threaded connection installed exactly the way the manufacturer specifies. Offered in 1-1/2" and 2" sizes, this OxBox adapter gives plumbers a compact, repeatable rough-in option as a code-recognized alternative to a full roof vent stack, packaged 6 EA per case for stocking rough-in crews.

Sioux Chief 696-11P – Frequently Asked Questions

1) What sizes does the Sioux Chief OxBox air admittance valve adapter come in?
Two trade sizes: a 1-1/2 inch PVC adapter (model 696-11P) and a 2 inch PVC adapter (model 696-12P). Pick the one matching the PVC DWV vent line you are tying into.
2) Can I use an OxBox air admittance valve instead of running a vent stack to the roof for an island sink?
That is the point of it. The OxBox Turbovent AAV adapter terminates a vent line locally, so fixtures like island sinks, remote lavatories, and other traps can be vented without carrying a stack to the roof. It is built for renovation work where extending to the roof is impractical. Local code still governs whether an AAV is accepted on your fixture, so verify with your inspector.
3) Can the OxBox AAV be buried inside a closed wall?
No. The manufacturer requires installation in an accessible location only, and it must sit upright and vertical. The OxBox housing is made for a behind-the-wall or under-floor rough-in, but the valve has to stay reachable, so plan for an access panel, cabinet interior, or open chase.
4) How does the OxBox adapter connect to PVC DWV pipe?
The adapter body is solvent-weld PVC, so it glues directly to 1-1/2 or 2 inch PVC DWV vent piping depending on which size you order. The valve itself lands on a threaded connection, and that thread gets sealed with PTFE tape only. Do not use pipe dope on it.
5) At what pressure does the Sioux Chief Turbovent valve open, and will it hold back sewer gas?
The Turbovent opens at .01 inch of negative pressure, so it admits air almost as soon as a draining fixture pulls a vacuum on the line. In the other direction it holds a positive seal against back pressure up to 13 psig, which is what keeps sewer gas out of the occupied space.
6) Do air admittance valves like this clog up with dust over time?
The Turbovent uses an internal actuating device that spins every time the valve cycles, which wipes the sealing surface clear of dust and debris. That self-cleaning action is why Sioux Chief specifies it for long-term operation rather than a static diaphragm.
7) How many OxBox AAV adapters come in a case?
Case quantity is 6 each, which is worth knowing if you are stocking a truck or roughing in multiple island sinks or remote lavs on the same job.
8) Is the Sioux Chief OxBox AAV adapter made in the USA?
Yes, the PVC body is manufactured in the United States, which matters on public and institutional jobs carrying domestic-content requirements.
