Eaton Crouse-Hinds TMCX125 1 NP Cable Gland - Explosion-Proof
Part Number: TMCX125 1 NP
Quick Summary
Eaton Crouse-Hinds TMCX125 1 NP cable gland delivers reliable termination for tray and armoured cables in hazardous industrial locations. Installing connectors in hazardous zones often leads to leakage, corrosion, or sealing failures under vibration or temperature swings. Certified for NEC/CEC Class I, Division 1, Class II, Division 1, Class III hazardous locations and NEMA 4X protections, it supports compliant, durable terminations. Designed for armoured, TECK armoured, and metal-clad tray cables, this gland also reduces installation time while meeting core safety standards. With a nickel-plated brass body and a 1-1/4 in NPT thread, it resists corrosion and provides a robust, long-term seal. Its sealing range of 0.87–1.39 in and the S-type cable sealing feature support a wide variety of tray cable configurations.

FAQs
For TMCX125 1 NP, use a 1-1/4" NPT mounting thread and ensure the cable sealing range of 0.87–1.39 inches matches your tray cable diameter. Follow IF 1647 installation guidelines, and use the S-type sealing for non-armoured or lightly armoured configurations. Verify armoured barrier compatibility (TECK/metal-clad) to maintain explosion-proof integrity.
The gland is rated for NEC/CEC hazardous locations, with Class I, Division 1, Class II, Division 1, and Class III classifications, plus NEMA 4X protection. Its nickel-plated brass body and TSC barrier design provide robust containment against ignition sources, while supporting armoured and metal-clad cables common in chemical plants and refineries.
Yes. It supports tray cables with armour types including armoured barrier, TECK armour, and metal-clad configurations. The cable sealing range and S-seal design accommodate a broad 0.87–1.39 inch diameter range, enabling use with various shielding and armour schemes while maintaining a secure seal.
Compliance is supported by NEC/CEC standards, with hazardous location ratings (Class I, II, III) and NEMA 4X protection. Additional installation and certification references include UL/Canadian certifications, installation sheets IF 1647, and Eaton's TMCX II literature for design verification.
The gland offers long-term reliability due to corrosion-resistant nickel-plated brass and a robust sealing system, reducing maintenance cycles and downtime in hazardous environments. Compatibility with standard fittings and existing Eaton components minimizes rework, while 3D CAD drawings and installation guides streamline commissioning and asset lifecycle management.
