Midland Industries 970306 Countersunk Cleanout Plug 1-1/2 in

Product Description

The MIDLAND INDUSTRIES 970306 is a countersunk cleanout plug designed for use in drain, waste, and vent piping systems where a flush or recessed finish is required at the cleanout access point. Machined from cast brass, it features a 1-1/2-inch male iron pipe (MIP) thread with a 1-1/2-11-1/2 thread form and is rated to 150 psi. The countersunk head profile sits below the surrounding surface when installed, reducing trip hazards and allowing finished flooring or covers to seat cleanly over the fitting. Licensed plumbers install this plug during rough-in and finish work on residential and light commercial drain systems.

This plug is suited for residential and light commercial plumbing applications where a cleanout access point requires a low-profile, pressure-rated closure. The 1-1/2-inch MIP connection matches standard cleanout tee fittings and body entries common in drain, waste, and vent piping. The cast brass construction holds up in both concealed and exposed installations, including floor-mounted cleanouts where corrosion resistance and mechanical durability are priorities.

Key Features

• Countersunk head design seats flush or below surface level for a clean, low-profile finish
• Cast brass construction provides corrosion resistance and long service life
• 1-1/2-inch MIP connection with 1-1/2-11-1/2 thread form for secure, leak-resistant engagement
• 150 psi pressure rating meets requirements for residential and light commercial drain systems
• Compact dimensions - 1.8 inches in diameter and 0.45 inches tall - minimize protrusion at the cleanout

Compatibility

Designed as an OEM-style replacement or new-installation cleanout plug for 1-1/2-inch female iron pipe (FIP) cleanout openings in residential and light commercial drain, waste, and vent piping systems.

Installation Notes

Installation is performed by a licensed plumber. Shut off the water supply and verify the system is depressurized before removing or installing any cleanout plug. Apply thread sealant tape or pipe dope to the MIP threads before hand-tightening, then snug with a flathead or square-drive wrench sized to the countersunk recess - do not overtighten cast brass fittings. Work must comply with the applicable edition of the International Plumbing Code (IPC) or the locally adopted plumbing code.
