SEPCO E37 E3 Series Zinc Plated Malleable Iron Conduit Enlarger, 1 - 1-1/4-Inch

SEPCO E37 E3 Series Zinc Plated Malleable Iron Conduit Enlarger, 1 - 1-1/4-Inch

The SEPCO E37 is a Zinc Plated Malleable Iron conduit enlarger from the E3 Series, engineered to transition a rigid conduit run from a 1-inch trade size up to 1-1/4-inch. This enlarger fitting provides a durable, corrosion-resistant connection point for electrical raceway systems where a size step-up is required between conduit sections, giving electrical contractors a straightforward way to move from a smaller conduit run into a larger trade size without cutting in a new box or re-routing the raceway. The Malleable Iron body combined with a Zinc Plated finish gives this fitting the strength and protective coating needed for demanding commercial and industrial conduit installations, and its rigid conduit threading is built to hold up under repeated handling on the job site.

Key Features

• Trade Size: Increases a conduit run from 1" to 1-1/4", allowing a size step-up mid-run without re-routing the raceway.
• Durable Construction: Malleable Iron body resists impact, drops, and mechanical stress on demanding job sites better than lighter die-cast alternatives.
• Finish: Zinc Plated coating adds corrosion resistance and a clean, uniform appearance for extended service life in conduit systems.
• Series: Part of SEPCO's E3 Series of conduit enlarger and conduit body fittings, sharing a consistent Malleable Iron platform.
• Function: Enlarger design lets electricians expand conduit trade size mid-run to match downstream equipment, box, or code requirements.
• Installation: Threaded connections at each end allow the enlarger to be installed inline with standard rigid conduit fittings and couplings.
