Nibco I026000 Dwv Adapter 1-1/4 in Spigot X Fipt Abs

Product Description

The NIBCO I026000 is an ABS (Acrylonitrile Butadiene Styrene) drain, waste, and vent adapter designed to transition between a spigot end and a female iron pipe thread (FIPT) connection in DWV piping systems. Sized at 1-1/4 inches, this adapter is rated for working temperatures from -40 degrees F to 180 degrees F and conforms to the ISO 9001:2008 quality standard. It is installed by licensed plumbers in residential and light commercial drain, waste, and vent applications where a spigot-to-threaded female connection is required. The lightweight construction at 0.05 pounds makes handling during rough-in straightforward.

This adapter is used in DWV piping systems where an ABS spigot pipe or fitting needs to connect to a female NPT-threaded fitting or fixture. Typical install scenarios include connecting ABS drain lines to threaded trap arms, cleanout plugs, or other NPTF-threaded DWV components in residential drain and vent rough-in work. The 1-1/4 inch size is common in lavatory drain and trap applications.

Key Features

• ABS construction provides corrosion resistance and durability in DWV service
• Spigot x FIPT end connections allow transition from plain-end ABS to female-threaded fittings
• Rated from -40 degrees F to 180 degrees F for standard DWV temperature ranges
• NPTF thread standard ensures a reliable threaded seal on the female end
• ISO 9001:2008 quality management certification
• Lightweight at 0.05 pounds, suitable for overhead and wall-cavity installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch ABS DWV piping systems using spigot-to-female-threaded connections.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local codes. Shut off water supply and clear the drain line of flow before beginning work. The spigot end is solvent-welded to ABS pipe or fittings using ABS cement; the FIPT end accepts a male-threaded fitting tightened to hand-tight plus the turns specified by the fitting manufacturer. Do not over-torque the threaded connection, as ABS threads can crack under excessive force.
