Appleton Century Crofts ELM90-50 IMC 90 Deg Elbow 1/2 in Threaded Iron Electro conduit

Application Fit

The Appleton ELM90-50 is a 90-degree threaded elbow designed for IMC conduit runs in hazardous locations. It connects two 1/2-inch male NPT ends and carries Class I, Division 1 and 2 ratings for Groups A through D, plus Class II and Class III coverage. Electricians specifying fittings for explosion-proof or dust-ignition-proof systems use this iron, electroplated fitting to change direction while maintaining the conduit’s protective integrity.

Installation Notes

The fitting threads directly onto 1/2-inch IMC or threaded RMC using standard pipe threads; no special tools are required beyond a conduit wrench. Because both ends are male, a coupling or female-threaded accessory is needed to join each side to the conduit system. The electroplated finish resists corrosion but can be damaged if overtightened, so apply firm hand pressure followed by a short wrench turn rather than full torque.

Compatibility Check

Verify that your existing conduit is 1/2-inch trade size IMC or threaded RMC with matching male NPT threads. Confirm the hazardous-area classification of the installation matches Class I Division 1 or 2, Groups A–D, Class II Division 1 or 2, Groups E–G, or Class III. Ensure the overall length of 1 1/2 inches fits within the available space between boxes or enclosures.
