IF 1890 - TMC3 Cable Gland
Armor compatibility and versatile gland type deliver business impact by enabling both armored and non-armored cable installations with a single gland, reducing inventory and installation time in plant refurbishments. This supports applications in control panels and outdoor wash-down zones, improving uptime through robust sealing and corrosion resistance from aluminum construction. The cable range of 1.150"–1.620" and armor range of 1.100"–1.400" provide broad compatibility with MC, MC-HL, TECK, TC, TC-ER, TC-ER-HL, ITC, ITC-ER, ITC-HL, PLTC, PLTC-ER and ACIC cables, minimizing the need for multiple gland sizes and enabling faster scoping for projects. The 1-1/4" NPT thread size aligns with standard conduit fittings, reducing the risk of misfit and ensuring reliable thread engagement in tight spaces. IP66 and NEMA 4X ratings offer strong ingress protection for wash-down environments and corrosive areas, enabling safer operation and longer service life. Certifications including NEC/CEC IECEx/ATEX and UL listings for hazardous locations simplify cross-border compliance, reducing design review time and accelerating commissioning. The durable aluminum exterior resists corrosion in chemical plants and offshore facilities, while the armored vs non-armored capability supports future-proofing and seamless upgrades without replacing hardware. Installation efficiency is enhanced by standardized dimensions (6.03 in length, 2.45 in width/height) that fit common panel layouts, helping mechanical teams achieve faster, repeatable seal alignment and consistent performance.
