IF 1890 - TMC3 Cable Gland
Stainless steel construction provides robust corrosion resistance. This reduces maintenance costs and extends service life in aggressive environments, such as chemical processing plants, mining facilities, and offshore installations. The gland supports both armored and non-armored MC cables, simplifying procurement and on-site assembly while reducing field rework and inventory complexity. Its 1" NPT thread and standard gland interface ensure compatibility with common enclosures and mounting layouts, accelerating commissioning and minimizing installation errors in control panels and electrical closets. Cable range of 1.150–1.620 inches and armor range of 1.100–1.400 inches accommodate a wide variety of MC cables, reducing the need for multiple gland variants and lowering total cost of ownership. With IP66, NEMA 4X, and NEC/CEC IECEx/ATEX certifications, it guarantees regulatory compliance and reliable performance across global sites, including chemical, refining, and offshore environments. Comprehensive technical documentation and installation support further shorten project timelines and improve field reliability, especially for OEMs and maintenance teams.

FAQs
The TMC3-100-2-SS uses a 1" NPT thread and stainless steel housing, compatible with common enclosures and mounting patterns. It supports both armored and non-armored MC cables within a 1.150–1.620 inch range, ensuring a tight seal in hazardous locations while allowing straightforward field assembly. Verify cable diameter to confirm armor range compatibility and ensure proper gasket seating for IP66 sealing in environments prone to dust and moisture.
This gland carries NEC/CEC IECEx/ATEX standards, IP66 ingress protection, and NEMA 4X enclosure ratings, with area classifications for hazardous/classified locations. These certifications support global deployments in chemical, oil & gas, mining, and other industries, ensuring compliance with safety and environmental requirements while reducing risk during audits and inspections.
Yes. The TMC3-100-2-SS is specified for armoured and non-armoured configurations, with armor range 1.100–1.400 inches. This flexibility simplifies sourcing and installation across projects that use different cable constructions, minimizing the need for multiple gland types and reducing inventory complexity on-site.
The gland’s stainless steel construction provides excellent corrosion resistance, contributing to longer service life and reduced maintenance. The 1" NPT interface and standardized dimensions speed up mounting and commissioning, while IP66/NEMA 4X protection ensures reliable sealing against dust and water ingress, lowering the total cost of ownership through fewer outages and more predictable performance in harsh environments.
