Midland Industries 970299 Cleanout Plug 1-1/4 in Mip Brass

Product Description

The MIDLAND INDUSTRIES 970299 is a raised square head cleanout plug designed for sealing drain and waste cleanout openings in plumbing systems. Machined from cast brass, it threads into a female-threaded cleanout fitting using a standard 1-1/4 inch MIP (male iron pipe) connection with a 1-1/4-11-1/2 thread specification. Rated to 250 psi, this plug provides a durable, pressure-resistant seal appropriate for residential and light commercial drain, waste, and vent applications. The raised square head design allows removal and reinstallation using a standard square-drive or adjustable wrench without rounding or damaging the fitting.

This cleanout plug is used in drain, waste, and vent (DWV) systems where access ports require a removable, pressure-rated closure. Typical applications include floor cleanouts, wall cleanouts, and inline cleanout tees in residential and light commercial plumbing. Licensed plumbers install this fitting during new construction rough-in or as a replacement plug in existing cleanout assemblies. Its cast brass construction makes it suitable for both wet and dry plumbing environments.

Installation Notes

Installation and removal should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before removing an existing cleanout plug. Apply thread sealant tape or pipe joint compound to the MIP threads before installation to ensure a leak-free seal. Do not overtighten; use a wrench on the square head only, never a pipe wrench directly on the plug body.
