EMT fittings from Konkore Fittings® are zinc plated and made from SAE 1006 steel and contain nylon insulating bushings. Konkore EMT fittings are similar to conventional EMT fittings both using either set-screw or compression rings to secure EMT pipes. Connectors are mounted to a metallic box using a steel locknut that screw on standard NPSM threads. Some also have nylon insulating bushings.
