Quick Summary

Eaton TMCX400 1 L cable gland provides rugged, explosion‑proof terminations for hazardous locations. Installers often struggle with sealing integrity, armored cable compatibility, and quick, compliant mounting in demanding environments. It carries NEC/CEC compliance and hazardous-location ratings (Class I, Division 1; Class II, Division 1; Class III) plus a NEMA 4X enclosure rating, delivering dependable performance in harsh conditions. By combining a liquid‑compound barrier with armoured sealing, it reduces field downtime and supports long‑term, maintenance-friendly installations. Designed for TECK armoured, metal‑clad with interlocked or welded corrugated armour, tray cable, and armoured barrier cables, it enables fast, reliable field terminations in industrial plants.

Explosion-proof protection is built into the TMCX400 1 L, ensuring safe terminations in Class I, Division 1 locations. This feature reduces ignition risk and simplifies compliance audits, allowing maintenance crews to work with confidence in refineries, chemical plants, and similar facilities. Armoured gland design provides a tight seal against liquids and dust while tolerating interlocked or welded corrugated armour. The result is longer service life, fewer gland replacements, and less rework during installation in demanding environments such as offshore platforms. The 4" NPT thread type aligns with common conduit entries, speeding installation and reducing the need for adapters. This compatibility supports quick panel entry solutions and minimizes field fit issues in standard electrical rooms and hazardous-area installations. Cable sealing range 1 (S) and the specified range 2.62-3.78" ensure a controlled, leak-free seal for mid-size TECK armoured cables. The liquid compound barrier further enhances ingress protection, improving reliability in wet or dusty environments. Aluminum construction paired with a NEMA 4X enclosure rating resists corrosion and weathering while maintaining structural integrity in harsh environments. This combination supports outdoor installations, washdowns, and long service life with reduced maintenance costs. Compatible with TECK armoured, metal-clad and tray cables, this gland offers versatile installation options and a consistent seal across cable families. The armoured barrier feature adds robustness for high-vibration or impact-prone applications.

FAQs

Verify gland rating and cable size (2.62–3.78 in). Power must be isolated before work. Thread the gland into a 4" NPT opening, apply the correct sealant, insert the armored cable, and tighten to the specified torque. Check seal integrity and ensure the enclosure remains weatherproof and explosion-safe after installation.
The gland supports TECK armoured and metal-clad cables with interlocked or welded corrugated armour, as well as tray cables. This broad compatibility reduces the need for multiple gland types and simplifies stocking for hazardous-location terminations in industrial facilities.
Yes. It aligns with NEC/CEC standards and hazardous-location ratings, including Class I Division 1, Class II Division 1, and Class III, plus a NEMA 4X enclosure rating. These certifications ensure safe operation in wet, corrosive, and explosive environments and simplify regulatory compliance.
Absolutely. The gland uses a 4" NPT thread and is designed for explosive environments. When installed with appropriate gaskets and sealants, it provides a robust, ingress-protected termination for conduits in Class I Division 1 installations.
The gland reduces downtime by delivering reliable sealing and quicker terminations in hazardous areas, lowering maintenance calls. Its rugged aluminum body and 4X rating extend service life, while NEC/CEC compliance minimizes regulatory risk and potential penalties, delivering measurable long-term cost savings.
