  • Schedule 40 rated for standard pressure systems

  • Operates from -40 °F to 180 °F
  • Meets ASTM D3965 cell class 32222

4-inch MNPT Cleanout Plug

This Schedule 40 ABS fitting provides a threaded closure for 4-inch drain waste and vent cleanout openings. It meets ASTM D3965 cell class 32222 for material quality and withstands temperatures from -40 to 180 degrees Fahrenheit. The male NPT threads allow direct installation into a female threaded adapter or fitting.

Schedule 40 pressure rating

The Schedule 40 designation confirms the wall thickness and pressure rating required for standard residential and light commercial drainage systems. Using a fitting with a different schedule would mismatch the pipe dimensions and compromise the joint integrity.

Suits standard DWV cleanouts.

This plug is intended for non-pressurised drain waste and vent cleanout access points. Installers needing a fitting rated for continuous internal pressure or a different pipe diameter should select an alternative product.

Questions about this item

What does the 180-degree Fahrenheit temperature limit mean when the plug is installed in a hot-water line?

The ABS material is rated for continuous service up to 180 °F, so it will hold pressure in typical residential hot-water systems without softening.

How does the MNPT thread standard affect the seal on a 4-inch Schedule 40 fitting?

The male NPT threads taper to create a pressure-tight joint when tightened into a matching female NPT opening, which is the standard connection method for this schedule.

What clearance is needed to thread a 4-inch Schedule 40 cleanout plug into an existing fitting?

You need enough access to engage the full male NPT length on a 4-inch Schedule 40 body, so allow space for a pipe wrench to turn the hex without obstruction.
