The ABS DWV double fixture tee features all hub connections and allows for a connection to be made in continuous pipe line and branch out to a different direction. Please refer to NIBCO technical data sheets and catalogs for engineering and installation information. Acrylonitrile-Butadiene-Styrene (ABS) is resistant to a wide variety of materials ranging from sewage to commercial household chemical formulations and can be exposed to a wide temperature span. ABS is lightweight, safe to handle and easy to install. ABS DWV is joined by solvent cementing or threading and can easily be connected to steel, copper, or cast iron through the use of transition fittings. NIBCO® plastic fittings are backed by a 5-year limited warranty. Because of its longstanding reputation for innovation and precision in design and manufacturing, NIBCO is the preferred brand in the industry.

Nibco I277450 – Frequently Asked Questions
1) What is a double fixture tee used for in an ABS DWV system?
A double fixture tee lets you keep a continuous vertical pipe line running while picking up branch connections off both sides, typically back-to-back fixtures like two lavatories or two kitchen sinks on opposite sides of a wall. The Nibco 5835-B version is all-hub, so the run and both branches take pipe directly into the socket.
2) How do you join the Nibco 5835-B ABS tee to the pipe?
Solvent weld. The hub sockets take ABS pipe with ABS solvent cement, no gaskets or threads. ABS DWV can also be joined by threading, and it ties into steel, copper, or cast iron through transition fittings when you are working into an existing building drain.
3) What pipe sizes does the Nibco 5835-B double fixture tee come in?
Five configurations: straight 2 inch, straight 3 inch, 2 x 1-1/2 x 2 x 2, 2 x 1-1/2 x 1-1/2 x 1-1/2, and 3 x 2 x 3 x 3. The reducing versions let you drop from a 2 or 3 inch stack down to 1-1/2 or 2 inch fixture arms without adding bushings.
4) Can this ABS DWV tee be used on a compressed air line?
No. Do not test or use ABS DWV fittings with compressed air or other gases. It is a drain, waste and vent fitting only, and testing should be done with water per your local code.
5) Does this Nibco ABS tee meet code for commercial plumbing, and what standards does it carry?
It is listed for both commercial and residential plumbing and carries CSA B181.1, ASTM D2665, ASTM D3965, ASTM D2661 and D3311, UL Listed 94V-0, NSF/ANSI Standard 14, and NSF U.P. certification. That combination is what most inspectors look for on an ABS DWV fitting.
6) What temperature range can ABS DWV fittings handle?
Minus 40 F to 180 F service temperature. That covers normal fixture drainage and dishwasher or laundry discharge, but it rules out anything dumping sustained high-temperature waste above 180 F, where a code-approved high-temp material is required instead.
7) Can I glue this black ABS tee to white PVC pipe?
Not directly. This is a black ABS fitting and ABS cement bonds to ABS. Where you have to meet PVC, use a transition fitting or a mechanical coupling approved by your local code rather than solvent welding the two materials together.
8) Will ABS hold up to drain cleaners and sewage waste?
ABS resists a wide range of materials from sewage through common commercial and household chemical formulations, which is why it is used on waste arms serving kitchens, laundries and janitor sinks. It is also light enough to hang and cut on site without special tooling.
9) What is the Nibco part number for the 3 inch double fixture tee?
The straight 3 inch hub version is I277600. The reducing 3 x 2 x 3 x 3 is I277650, the straight 2 inch is I277450, and the two 2 inch reducers are I277500 and I277550.
