Brass Threaded Plug 3 in

The Oatey 42372 is a brass threaded plug designed for 3-inch nominal pipe size. It provides a secure closure for drain lines during installation, testing or permanent sealing. Plumbing professionals and DIY users select it for reliable shut-off in residential and commercial systems.

Fits 3-inch threaded openings

The plug threads directly into a 3-inch female fitting without additional adapters or tools beyond a wrench on the square drive. Its brass construction resists corrosion and allows removal when access is needed again. It frees the installer from solvent-weld caps that cannot be reused.

Rated for 10 psi testing

The plug withstands a maximum operating pressure of 10 psi for hydrostatic tests. Brass threads seal cleanly without galling and the square drive accepts a standard wrench for firm tightening. No power tools or lubricants are required for normal installation.
