SEPCO NTC-350 Rigid Conduit Connector, 3-1/2" Zinc-Plated Malleable Iron

SEPCO NTC-350 Rigid Conduit Connector, 3-1/2" Zinc-Plated Malleable Iron

The SEPCO NTC-350 Rigid Conduit Connector is a 3-1/2" fitting manufactured from zinc-plated malleable iron, purpose-built to join rigid metal conduit (RMC) runs to boxes, panels, and equipment enclosures. Malleable iron construction gives the NTC-350 the mechanical strength needed to withstand the demands of rigid conduit installations, while the zinc-plated finish adds a layer of corrosion protection for longer service life. As a rigid connector, the NTC-350 is designed to create a secure, stable termination point between 3-1/2" rigid conduit and the enclosure it feeds, helping maintain a properly grounded and mechanically sound raceway system. SEPCO offers the NTC-350 as part of its line of rigid conduit fittings for electrical contractors and facility maintenance teams working on commercial, industrial, and institutional projects.

Key Features

• Trade Size: Sized for 3-1/2" rigid metal conduit, allowing the connector to terminate larger-diameter RMC runs into enclosures, panels, and junction boxes.
• Malleable Iron Body: Constructed from malleable iron, a material valued in conduit fittings for its combination of strength and workability, helping the connector resist the stresses of rigid conduit installation and ongoing use.
• Zinc-Plated Finish: The zinc-plated surface treatment provides a protective barrier that helps guard the connector against corrosion in typical electrical installation environments.
• Rigid Connector Design: Configured as a rigid connector, the NTC-350 is intended to attach rigid metal conduit directly to boxes, panels, and equipment housings, supporting a continuous and mechanically secure raceway.
• Compatibility: Sized specifically to pair with 3-1/2" rigid conduit, making it a matched fitting choice for contractors standardizing on this conduit size across a job.
