When used with TSC sealing compound, ES hubs can seal horizontal conduit runs at enclosures. TSC epoxy sealing compound is a two-part epoxy sealing compound that may be used to seal ES sealing hubs. It is quick and easy to measure, mix and install. The compound is kneaded until a uniform color is obtained. It is then packed around the conductors to effectively seal the cable.
