The ABS DWV 90-degree water closet elbow features a spigot x hub connection and is specially designed to connect to the bottom of the closet flange. 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 I055800 – Frequently Asked Questions

1) What size is the Nibco 5807-CL closet elbow and what does it connect?
The 5807-CL is a 4 inch by 3 inch reducing closet elbow, so it takes a 3 inch drain line up to a 4 inch outlet under the toilet. It is a 90 degree (1/4 bend) fitting made to connect to the bottom of the closet flange, and it comes with a cap.
2) Is the Nibco 5807-CL hub x hub or spigot, and how do I join it?
The fitting's end connection type is listed as hub x hub, and joining is by solvent weld. You cut the pipe square, prime and cement, and push into the socket. No threading or gasket is involved. ABS DWV can be tied into steel, copper or cast iron lines using transition fittings.
3) Can I use this ABS closet elbow on a pressure or vent line as well as the toilet drain?
It is a DWV (drain, waste, vent) fitting only, Schedule 40 ABS. Never test or use it with compressed air or other gases. It is not a pressure fitting.
4) Does the Nibco 5807-CL meet code for a multi-family or institutional job?
The fitting is manufactured to ASTM D2665, D3965, D2661 and D3311, plus CSA B181.1. It is UL Listed 94V-0, certified to NSF/ANSI Standard 14, and NSF U.P. Certified for use in potable-adjacent drain, waste and vent systems. Those are the listings most inspectors on commercial and multi-family work look for.
5) Can I mix this black ABS closet elbow with white PVC DWV pipe?
No. This is black ABS (acrylonitrile butadiene styrene), and ABS solvent cement bonds ABS to ABS. If the rest of your stack is PVC, use a PVC closet elbow or a mechanical transition coupling rather than cementing dissimilar plastics together.
6) Will this ABS elbow handle hot waste from a commercial kitchen or laundry?
Service temperature range is -40 F to 180 F, which covers normal hot waste discharge. The ABS material resists everything from sewage to common household and commercial chemical formulations. It is approved for both commercial and residential plumbing systems.
7) Why choose a closet elbow instead of a standard 90 degree ABS elbow under a toilet?
A standard 1/4 bend is not made to land on a closet flange. The 5807-CL is a purpose-built closet elbow that reduces 4 inch to 3 inch and is designed to connect to the bottom of the flange, so the flange seats at the right height with no adapter stack. Use a plain DWV 90 for branch and stack turns instead.
