The ABS DWV male adapter features a spigot x male NPT thread connection and provides a means for adapting a solvent weld connection to a threaded connection. 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 I032100 – Frequently Asked Questions
1) Can I thread a Nibco 5804-2 male adapter into a steel or cast iron drain line?
That is what the fitting is for. The 5804-2 has a spigot end on one side and a male NPT thread on the other, so the ABS solvent weld side glues into your DWV run and the threaded side screws into steel, copper, or cast iron through a transition connection. Keep it on drain, waste, and vent service only, and never test or run it with compressed air or other gases.
2) What pipe sizes does the Nibco 5804-2 ABS male adapter come in?
Six sizes: 1-1/4, 1-1/2, 2, 3, and 4 inch, plus a 1-1/2 x 1-1/4 inch reducing version that lets you drop from a 1-1/2 inch spigot down to a 1-1/4 inch thread without a separate bushing. All of them are Schedule 40 ABS.
3) Will a spigot end ABS adapter fit inside my existing fitting, or do I need a socket?
Spigot means the ABS end is sized like pipe, not like a socket. It goes INTO the hub of an existing Schedule 40 ABS fitting and gets solvent cemented there. If what you have is a length of pipe with no hub waiting for it, you want a socket (hub) style adapter instead, or a coupling to receive this one.
4) Is a black ABS adapter OK to mix with white PVC DWV pipe?
No. The 5804-2 is ABS, and ABS and PVC are different materials that take different cements; a solvent weld between them is not a listed joint under the standards this fitting is built to. If your run is white PVC DWV, use a PVC male adapter of the same size. If your run is black ABS, this is the match, and the fitting is black to suit.
5) Does the Nibco 5804-2 ABS adapter meet code for a commercial building or a healthcare facility?
It carries the standards an inspector looks for on ABS DWV: ASTM D2661, D2665, D3311, and D3965, CSA B181.1 for Canadian work, NSF/ANSI Standard 14 with NSF U.P. certification, and UL Listed 94V-0. Nibco lists it for both commercial and residential plumbing. Local amendments still govern, so match the standard your drawing calls out.
6) How hot can waste water get before an ABS DWV male adapter is a problem?
Service range runs from -40 F to 180 F, which covers dishwasher and laundry discharge and unheated crawl spaces or attics. What it does not cover is a boiler drain, a steam condensate line, or anything on the pressure side of a system. This is a drainage fitting, not a pressure fitting.
7) What do I need on hand to install a Nibco ABS male adapter besides the fitting?
ABS solvent cement for the spigot side (one step, no primer required for ABS the way PVC needs it), and thread sealant rated for plastic on the male NPT side. Thread the joint hand tight plus a turn or two with a strap wrench; over-torquing a plastic male thread splits the female fitting it goes into. Nibco publishes plastic fittings installation instructions for the cementing procedure.
8) Which size Nibco male adapter do I use for a 1-1/2 inch trap arm going into a 1-1/4 inch threaded connection?
The reducing version, MPN I032070, covers exactly that: a 1-1/2 inch spigot to a 1-1/4 inch male thread in one piece. It saves you stacking a bushing behind a straight adapter, which is one less joint under a sink where access is tight.
9) Should I use a male adapter or a female adapter on my ABS drain line?
Go by which half of the joint carries the female thread. A male adapter like the 5804-2 puts the NPT male thread on the plastic, so it screws into a threaded female opening, a floor drain body, a cleanout ferrule, or a female iron fitting. If the mating part is a male thread instead (a trap adapter nipple, a threaded riser), you need the female pattern. Both sides of this one are fixed: spigot for the cement joint, male thread for the mechanical joint.
10) Can I use a 3 or 4 inch ABS male adapter on a buried building drain?
The 3 and 4 inch sizes (MPN I032150 and I032200) are Schedule 40 ABS DWV, made for gravity drainage, and ABS holds up against sewage and household chemical formulations. Underground use is governed by your local code and bedding requirements, and the joint itself must stay a drainage joint, never pressure tested with air.
11) Is ABS DWV pipe fitting light enough for overhead work on a multi-family retrofit?
ABS is lightweight and safe to handle, which is the main reason crews pick it over cast iron for repipes in occupied buildings. The tradeoff is noise transmission compared with cast iron, so on stacks running behind a bedroom wall many specs still call for iron or a wrap. For a straight fixture branch or vent, this adapter is the simple way to land the plastic on a threaded connection.
