EMI-Shielding Flexible Plastic (MPT) Conduit and Fittings

A braided copper cover defends against electromagnetic interference (EMI) that can distort or disrupt signals. Install shielded MPT in areas where motors, generators, and other equipment that emit EMI are running. It has a corrugated nylon core that flexes to make tight bends and is typically used indoors. Pair conduit with nickel-plated brass connectors for a fully shielded run.
