OATEY 42369 1-1/2 in. 185 Brass Cleanout Plug

Yes. The Oatey 42369 is a 1-1/2 inch brass cleanout plug and fits 1-1/2 in. fittings. It is female threaded, so it threads into a male-threaded cleanout adapter or fitting hub rather than over one. Match your fitting size before ordering: a 2 inch cleanout tee needs a 2 inch plug, not this one.

It does. The 42369 is built with a raised square head specifically to satisfy Southern Plumbing Codes that require one. If your inspector is calling out a raised-head plug rather than a countersunk or flush plug, this is the style they are asking for.

Maximum working pressure is 10 psi. That is a drain, waste and vent rating, not a supply rating. Use it to cap off DWV cleanouts and keep sewer gas out of the building; do not put it on any pressurized water line.

Slip joint pliers. The raised square head gives you something to grab, so tightening and later removal are done with pliers rather than a hex socket or an internal wrench. That raised head is also why it is easier to break loose years later than a flush countersunk plug that has corroded into the fitting.

Go raised head where code requires it (Southern Plumbing Codes call for one) and wherever you want the plug to come out easily later, since the square head can be gripped with pliers. A countersunk or flush plug is the choice when the cleanout sits in a finished floor or a traffic area and a protruding head would be a trip hazard or interfere with a cover plate. The Oatey 42369 is the raised square head version in 1-1/2 inch brass.

Brass is the choice where the plug gets opened repeatedly. The 42369 is a durable brass body, so the square head and threads stand up to being wrenched on for rodding and snaking without rounding off the way a plastic head can. For a cleanout a property manager or service plumber expects to open more than once, brass is the practical pick.

The plug weighs 0.138 lb. It is a small single-piece brass fitting, which is why MRO and maintenance buyers usually stock a handful of them on the truck or shelf rather than ordering one at a time.
