Cleanout Plug Specifications

The Oatey 42740 is a 1.5 in brass cleanout plug with a threaded connection and a slotted, recessed head. It fits a nominal pipe size of 1.5 in and carries no stated maximum operating pressure. This component seals a drain access point in residential or light-commercial plumbing systems.

Suitable Installations and Limits

The plug suits installers who need a corrosion-resistant brass closure for a 1.5 in threaded cleanout opening and can apply torque with a standard slotted driver. It is not intended for pressurised systems that require a rated pressure seal, nor for pipe sizes other than the stated nominal diameter.

Deciding Specification

The 1.5 in nominal pipe size and matching 1.5 in outside diameter are the critical dimensions that determine whether this plug will thread correctly into the existing fitting.
