Brass Flush Plug for Electrical Enclosures

The Hubbell S5007 is a round flush plug machined from solid brass for sealing unused openings in electrical boxes and enclosures. It provides a durable, corrosion-resistant closure that maintains the integrity of the installation. This component is designed for professional electricians and maintenance teams completing conduit or junction box work.

Suited for Sealing Single Knockouts — Not

This plug suits installers who need to blank off a single round knockout in a metal or non-metallic box. It does not accommodate cable entry, so buyers running new conductors through the opening should select a suitable connector or cable gland instead. Projects requiring multiple sealed ports will require one plug per opening.

Round Brass Construction Determines Fit

The critical specification is the round brass body, which dictates compatibility with standard round knockout dimensions. The material ensures long-term resistance to oxidation and mechanical wear inside the enclosure. Verify the knockout diameter matches this plug before ordering.

Questions about this item

Should I choose the S5007 brass insert over another version?

The S5007 is a round flush plug made of brass. Select it when the application calls for a brass round insert; other versions would have a different shape or material.

What does the brass material mean once the insert is installed?

Brass resists corrosion and provides good conductivity, so the insert holds up in damp locations and maintains a reliable electrical path.

Does the round shape limit the conduit or fitting size I can use?

The round profile matches standard round openings; it does not impose a separate size limit beyond the box opening it sits in.
