  • Schedule 40 ABS handles -40 °F to 180 °F

What This Plug Seals

This Value Brand cleanout plug closes a 1-1/2 inch MNPT threaded opening in ABS piping. It is intended for residential or light-commercial drainage systems where a removable access point is required. The Schedule 40 rating matches standard DWV pipe dimensions.

MNPT Thread Compatibility

The single specification that determines fit is the Male National Pipe Thread connection. Only female-threaded fittings or adapters with the same nominal size and thread standard will seal correctly. Mismatched thread types will leak.

Temperature Range In Service

The ABS body is rated for continuous operation from -40 to 180 degrees Fahrenheit. Within this span the material retains impact strength and dimensional stability. Sustained exposure above the upper limit softens the fitting and risks deformation under system pressure.

Questions about this item

What does the 180 °F temperature limit mean when the plug is installed in a real drain line?

The plug is rated for continuous service up to 180 °F, so it will hold its shape and seal on typical residential hot-water waste lines without softening or leaking.

How does the MNPT thread standard control what this plug connects to?

MNPT gives a 1-1/2 inch male tapered pipe thread that seals against a matching female NPT fitting; the taper creates the mechanical seal so no separate gasket is required.

What clearance and wall thickness does the Schedule 40 body need to fit correctly?

Schedule 40 defines the wall thickness for 1-1/2 inch nominal pipe, so the plug fits standard ABS DWV sockets and clears the hub depth used in residential drain, waste and vent systems.
