Quick Summary

The TMCX250 1 SS L cable gland is an explosion‑proof sealing solution for armored cables used in hazardous locations. Engineers often struggle with ingress protection, unreliable seals, and regulatory hurdles in harsh industrial environments. This gland meets NEC/CEC requirements, offers a NEMA 4X rating, and is rated for Class I, II, and III hazardous locations, simplifying compliance. Its stainless steel construction and armoured barrier design deliver long service life in demanding applications such as feeders, motors, and instrumentation runs. By supporting TECK and metal-clad cables with a precise sealing range, it reduces maintenance downtime and total ownership costs for facilities operating in hazardous areas.

Feature: 2-1/2 inch NPT thread size provides a proven, industry-standard connection for robust enclosure integration. Benefit: Simplifies installation with widely available fittings and consistent torque characteristics, reducing field rework and enabling faster commissioning in new builds or retrofits. Application: Motor control centers and hazardous-area panels where reliable sealing and certified termination are critical. Feature: Cable sealing range of 1.81–2.72 inches accommodates common armour diameters without multiple gland variants. Benefit: Reduces spare parts inventory while ensuring a tight ingress seal across a broad cable set, lowering stocking costs and downtime. Application: Field terminations in chemical plants and refineries where cable diameters vary. Feature: Stainless steel construction delivers corrosion resistance and durability in harsh environments. Benefit: Extends service life in aggressive chemicals, moisture, and temperature variations, decreasing replacement cycles and maintenance spend. Application: Offshore platforms, mining, and heavy-industrial installations. Feature: Armoured barrier and TECK armoured/metal-clad cable compatibility with interlocked or welded corrugated armour. Benefit: Enhanced mechanical protection against abrasion and impact, improving protection for cables in trays and conduits. Application: Cable runs in industrial facilities with heavy equipment or dense routing. Feature: Liquid barrier sealing and explosion-proof protection type. Benefit: Meets stringent safety codes while providing reliable performance in hazardous locations, supporting compliant installations and reduced inspection findings. Application: Electrical cabinets and field junctions in Class I, II, III environments. Feature: Certifications and compliance with NEC/CEC, NEMA 4X, and hazardous-location ratings. Benefit: Streamlines procurement and qualification processes, reducing project risk and accelerating approval workflows. Application: Regulatory-compliant installations across power, process, and automation systems.

FAQs

Installation starts with confirming a 2-1/2" NPT interface and the cable diameter falls within 1.81–2.72 inches. Apply appropriate thread sealant or tape, torque to manufacturer specs, and fit the gland with the liquid barrier sealing for armoured cables. Verify the assembly maintains the 4X enclosure integrity and ensure conductors remain within permitted temperature and ingress limits per NEC/CEC guidelines.
The gland is designed for Hazardous/Classified Locations and supports NEC/CEC requirements, including Class I, Division 1, Class II, Division 1, and Class III environments. It carries a NEMA 4X rating, offering weather and corrosion resistance in hazardous areas and aligning with UL certifications referenced in the product literature.
Compatible with armoured barrier, metal-clad with interlocked or continuously welded corrugated armour, TECK armoured, and tray cable configurations. The sealing range accommodates cables from 1.81 to 2.72 inches in diameter, enabling use with common industrial cables without multiple gland variants.
Key advantages include a sturdy 2-1/2 inch NPT thread, stainless steel construction for corrosion resistance, and a liquid barrier that enhances ingress protection. It also supports multiple armour types (armoured barrier, TECK, tray), reducing stocking complexity and enabling quicker commissioning in hazardous locations.
The gland delivers longer service life in harsh environments due to stainless steel construction and robust armour compatibility, reducing maintenance frequency. Compliance with NEC/CEC and NEMA 4X minimizes regulatory risk, lowers Downtime costs, and improves overall system reliability for critical automation in hazardous locations.
