Cleanout Adapter with Plug

This ABS fitting connects a 3-inch female NPT thread to a spigot end for drainage cleanout access. It is intended for plumbers and maintenance crews who need a removable inspection point in non-pressure piping systems. The Schedule 40 rating confirms standard wall thickness for typical residential and light commercial waste lines. The plug seals the opening when inspection is not required.

Build Quality and Daily Use

The body is moulded from ABS meeting ASTM D3965 cell class 32222, giving resistance to impact and common drain chemicals across a temperature span of -40 to 180 degrees Fahrenheit. The spigot end slips into a hub or coupling for solvent welding, while the FNPT thread accepts the included plug with standard pipe tape or sealant. No special tools are needed beyond a strap wrench for the plug and solvent cement for the spigot joint.

Upgrade Context and Fit

This adapter replaces a glued-in cleanout tee or a missing access point in existing 3-inch ABS drainage stacks. The jump is worth it when code requires a threaded cleanout at a specific location or when a previous solvent-welded plug has cracked and leaks. It does not suit pressure-rated applications, copper or PVC systems without transition fittings, or installations where a larger cleanout diameter is specified.
