Halex/scott Fetzer 91530 Combination Coupling 1/2 to 3/8 Inch 15 Pack

Product Description

The HALEX/SCOTT FETZER 91530 is a combination coupling designed to connect 1/2 inch electrical metallic tubing (EMT) to 3/8 inch flexible steel conduit in a single fitting. The set screw design provides a secure mechanical connection without the need for special tooling beyond a standard screwdriver or nut driver. Constructed from die cast zinc, this coupling delivers solid corrosion resistance suitable for typical indoor electrical installations. Each package contains 15 couplings, making it a practical choice for electricians stocking up for rough-in work or panel runs requiring transitions between EMT and flex.

This coupling is used wherever a conduit run transitions from rigid EMT to flexible steel conduit, a common scenario at equipment connections, junction points, and motor terminations in residential and light commercial electrical work. The 1/2 inch to 3/8 inch size pairing is frequently encountered in branch circuit wiring and equipment whip applications. Licensed electricians install these fittings as part of compliant conduit systems under NEC requirements.

Key Features

• Combines EMT and flexible steel conduit in one fitting, eliminating the need for two separate connectors
• Set screw attachment provides a firm, tool-tightened connection on both conduit ends
• Die cast zinc construction for durability and corrosion resistance in standard indoor environments
• 1/2 inch EMT side to 3/8 inch flexible steel conduit side in a single body
• Packaged in a UPC polybag with 15 units per pack for efficient jobsite stocking

Compatibility

Designed for use with 1/2 inch electrical metallic tubing (EMT) and 3/8 inch flexible steel conduit. Suitable as a standard OEM-style transition fitting in residential and light commercial conduit systems.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify absence of voltage before making any conduit connections. Tighten set screws with a flat-blade screwdriver or appropriate nut driver to ensure a secure mechanical and grounding continuity connection. Do not overtighten set screws, as this may damage the conduit or fitting body.
