OATEY 42373 – Frequently Asked Questions
1) Will the Oatey 42373 brass cleanout plug thread into a 3-1/2 inch cleanout fitting?
Yes. The Oatey 42373 is a 3-1/2 inch plug and fits 3-1/2 in. fittings. It is female threaded, so the threads are on the inside of the plug body and it goes over a male cleanout ferrule or adapter, not into a female hub. If what you have in the floor or wall is a female-threaded fitting, this is the wrong direction of thread for it.
2) Can a brass cleanout plug be used on a pressurized line?
No. The 42373 brass plug carries a maximum working pressure of 10 psi, which makes it a drain, waste and vent part only. It caps off the pipe to help keep sewer gas out of the building. Do not put it on a water supply line or any pressurized system.
3) Is the Oatey 42373 cleanout plug acceptable under Southern plumbing codes?
It meets Southern Plumbing Codes that require a raised square head. The raised square head is the feature those codes call for, and it also gives you something to grab when you back the plug out later.
4) What tool do I need to install the Oatey 42373 cleanout plug?
Slip joint pliers. The raised square head is made to be gripped and tightened by hand tools, so no special wrench or socket is needed. A pipe wrench works too, but pliers on the square head is what Oatey calls for.
5) Is a brass cleanout plug worth it over a plastic one for a rental property?
Brass is the choice where the plug gets pulled repeatedly for rodding or where the square head takes wrench abuse, since a plastic head can round off or crack. The 42373 is a durable brass body at 0.4 lb, with a raised square head for repeated removal. For a property manager snaking the same stack every year, that reusability is the argument.
6) What is the Oatey part number for the 3-1/2 inch brass cleanout plug?
Order Oatey 42373. It is the 3-1/2 in. 185 brass cleanout plug with the raised square head, sold as a single plug.
