2.5 in Brass Cleanout Plug

This Oatey 42742 plug seals a 2.5 in nominal pipe opening with a brass threaded body and a slotted recessed head. It installs directly into compatible drain fittings to provide a secure closure for maintenance access. The durable brass construction resists corrosion in standard plumbing environments.

Suited for standard drain maintenance

Plumbers and facility crews needing a reliable 2.5 in threaded brass plug for cleanout access will find this part fits the spec. Installations requiring a different drive style, a non-threaded connection, or a larger nominal size must select an alternative component.

2.5 in nominal pipe size

The 2.5 in nominal pipe size is the critical dimension that determines compatibility with the existing fitting. Verify the pipe specification before ordering to ensure the threads engage correctly and the plug seats properly.

Questions about this item

What does the 2.5 inch nominal pipe size mean when fitting this plug?

It matches a 2.5 inch nominal pipe, giving a 2.5 inch outside diameter thread that seals the cleanout opening in standard drainage systems.

What does the threaded brass interface cap in practice?

The tapered brass threads create a metal-to-metal seal that resists corrosion and handles typical drainage pressures without a separate gasket.

What does the recessed slot head need for installation or removal?

A wide flat-blade screwdriver or a cleanout plug wrench engages the internal slot so the plug can be tightened or removed from inside the fitting.
