Part Number: TMC3-100-1-SS
Quick Summary
The TMC3-100-1-SS cable gland from Eaton provides robust sealing for armored and non-armored MC cables in challenging industrial environments. Engineers often wrestle with moisture ingress, corrosion, and mounting compatibility in hazardous plants, and this gland addresses those pain points with a stainless steel construction and a reliable 1" NPT connection. Its safety credentials span hazardous/classified locations, IP66 enclosure protection, and NEMA 4X enclosure duty, complemented by IECEx/ATEX and NEC/CEC standards for global compliance. For procurement and maintenance teams, rugged durability combined with broad cable compatibility translates into reduced replacement intervals and lower lifecycle costs. The gland’s armoured and non-armoured capability, plus compatibility with MC and related cable types, supports streamlined sourcing and installation across multiple sites.
