SEPCO P1 Die Cast Zinc Slotted Plug with NPT Threads

The SEPCO P1 Die Cast Zinc Slotted Plug is a rugged threaded closure fitting engineered to seal unused openings in conduit bodies, enclosures, junction boxes, and other raceway hardware. Manufactured from die-cast zinc for corrosion resistance, dimensional stability, and long-term durability, this slotted plug features 1/2-Inch NPT threads for a secure, tapered-thread fit into standard tapped openings. Its slotted head accepts a standard screwdriver for quick installation and removal, making it a practical, low-cost solution for electricians closing out spare knockouts, hubs, or conduit body access openings on commercial and industrial raceway and enclosure systems. The compact, low-profile design keeps the finished installation neat while maintaining a tight, debris-resistant seal at the threaded opening.
