RYMCO Rigid Metal Conduit (RMC) is manufactured from high grade mild steel, which is highly resistant to damage while being easy to cut, bend and thread on the job. The conduit is produced in nominal trade sizes from ½-6 inch in standard lengths of 10ft (3.05m) including the coupling, threaded on both ends per industry standards (ANSI B1.20.1). The taper of the threads are 3/4in. per foot (1 in 16) and are protected after cutting with an application of molten zinc. Color-coded end caps are applied opposite the couplings to protect the threads and provide quick visual indication of trade sizes
Coatings: The interior and exterior surfaces of Rymco RMC conduit are hot dipped galvanized with special high grade zinc, along with C Coat for added protection against corrosion and to allow for easier wire pulling and pushing. Providing users and specifiers with a level of confidence in Rymco conduit for a variety of applications and environments.
Application: Rymco’s RMC can be installed in all occupancies and locations, including Class 1 Division 1 hazardous locations. Rigid steel conduit is recognized in the NEC Section 250.118 as an acceptable equipment grounding conductor and offers shielding against electromagnetic fields generated during normal operation of electrical installations.
