4 in FNPT Spigot Adapter
This cleanout adapter connects a 4 in female NPT thread to a spigot end using ABS material. It meets ASTM D3965 cell class 32222 and operates from -40 to 180 degrees F. The Schedule 40 rating confirms standard wall thickness for drainage and vent systems. A plug is included to seal the opening when access is not required.
Suits DWV and low pressure lines
Installers working on residential or light commercial drain, waste and vent piping will find the fitting matches code requirements for ABS Schedule 40 systems. The temperature range supports typical soil and vent conditions. Projects that require pressure rated joints, solvent weld only connections, or non ABS compatible piping should select a different fitting type.
Plug provides removable closure
The supplied plug threads into the FNPT port to create a watertight cleanout seal that can be removed for maintenance or inspection. No additional gaskets, solvent cement or tools are bundled with the adapter. The plug material matches the ABS body for consistent chemical resistance and thermal expansion.

Questions about this item
Does the 4 in FNPT connection fit my existing 4-inch ABS drain pipe?
The adapter uses a 4 in FNPT thread on one end and a spigot on the other. It connects to a female-threaded cleanout body or fitting of matching size and schedule.
Will this Schedule 40 ABS adapter bond to the older ABS piping already in my house?
Yes, the fitting is made from ABS material rated to ASTM D3965 cell class 32222. Use ABS solvent cement compatible with Schedule 40 pipe for a permanent joint.
How can I verify the plug seals correctly after I solvent-weld the adapter in place?
Thread the included plug into the FNPT opening by hand, then tighten with a wrench. Run water through the system and check the joint and plug face for any leaks.
