The gland carries NEC/CEC and IECEx/ATEX certifications and supports hazardous/classified locations. This regulatory alignment helps with compliance documentation, enables safe operation in potentially explosive atmospheres, and facilitates approvals for installations in industrial processing plants and similar environments.
Yes. The gland uses a standard 1-1/4" NPT thread and a nickel-plated brass body, with installation guidance available in Eaton’s IF 1890 TMC3 instruction sheet. Its armor and cable range variants reduce the need for multiple fittings, speeding up commissioning and enabling consistent sealing performance across applications.
IP66 and NEMA 4X protection minimize ingress, corrosion, and washdown damage, extending service intervals and reducing maintenance costs. The versatile armor range and material choice provide durable performance in outdoor and chemical plants, contributing to lower lifecycle costs and improved plant reliability.
Choosing an armoured and non-armoured capable gland reduces SKU proliferation and simplifies procurement. It provides a universal sealing solution for mixed cable types, enabling faster upgrades, easier stocking, and consistent performance across retrofits and new builds in hazardous or demanding environments.
