IMC Pipe


RYMCO Intermediate Metal Conduit (IMC) is manufactured in the same manner as our RGC but with 33% less steel which results in 1/3 less weight and slightly larger inside diameter. The conduit is produced in nominal trade sizes from ½-4 inch in standard lengths of 10ft (3.05m) including the coupling and threaded on both ends. The taper of the threads is 3/4in. per foot (1 in 16) and are protected after cutting with an application of molten zinc. Rymco IMC protects insulated electrical conductors and cables from magnetic, damage, impact and crushing. Color-coded end caps are applied opposite the couplings to protect the threads and provide quick visual indication of trade sizes.

Coatings: Rymco IMC exterior is hot-dipped galvanized with special high grade zinc along with C Coat for added protection against corrosion. In addition to the galvanizing process, the interior of the conduit has a FreedomCoat® layer for rust prevention 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 IMC can be installed in all occupancies and locations, including Class 1 Division 1 hazardous locations and 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.
