The PVC DWV trap adapter features a spigot x slip joint connection and provides a means for adapting a solvent weld connection to a slip joint connection. Please refer to NIBCO technical data sheets and catalogs for engineering and installation information. Polyvinyl chloride (PVC) is the most frequently specified of all thermoplastic materials because of its light weight, durability, and cost-effectiveness. PVC DWV is easy to install and is joined by solvent cementing or threading. PVC fittings exhibit high corrosion and chemical resistance and will not rust, scale, pit or corrode. 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 K014650 – Frequently Asked Questions
1) What does the Nibco 4801 PVC DWV trap adapter actually connect?
It bridges a solvent weld system to a slip joint connection. One end is a spigot (Spg), which glues into the hub of a DWV fitting, and the other is a slip joint (SJ) that takes a tubular trap arm or tailpiece with a nut and washer. That is how you get from the PVC drain stub-out to a P-trap under a sink or lav.
2) Can I use this PVC trap adapter on a hot water or condensate line running above 140 degrees?
No. Maximum service temperature is 140 degrees F, and it's a drain, waste and vent fitting only. High temperature discharge from a commercial dishwasher or boiler blowdown needs a different material. Also never test or run it with compressed air or other gases.
3) Does the Nibco 4801 adapter match Schedule 40 PVC DWV pipe?
Yes, it's a Schedule 40 PVC fitting made to ASTM D2665, the standard for PVC DWV pipe and fittings, so the spigot end solvent welds into standard Sch 40 DWV hubs. White PVC throughout.
4) Does the slip joint nut and washer come with the Nibco 4801 adapter?
Plan on supplying the slip joint nut and washer separately, along with solvent cement and primer for the spigot end. The adapter itself is the PVC body with a spigot end and a slip joint end.
5) Which Nibco part number do I order for a 2 inch trap adapter?
The 2 inch size is MPN K014650. The others run K014500 for 1-1/4 inch, K014550 for 1-1/2 inch, and K014600 for the 1-1/2 x 1-1/4 inch reducing adapter.
6) Will a PVC trap adapter hold up in a janitor closet or commercial kitchen drain where chemicals go down?
PVC resists corrosion and chemical attack and won't rust, scale, pit or corrode, which is why it's standard for DWV branch work in commercial buildings. The limit is heat, not chemistry: keep the discharge at or below 140 degrees F.
