Eaton Specification Sheet - TMCX4140 BR NP
Feature → Business Impact → Application: Explosion-proof protection and dual barrier options (Armoured Barrier and Non-armoured Barrier) ensure compliant sealing in hazardous environments, reducing risk of dust, moisture, or gas ingress and enabling safer operation of TECK-armoured tray cables in chemical refineries and oil & gas facilities. This translates to measurable safety improvements and compliance confidence during audits. Application: Use in plants with strict hazardous-location requirements to protect electrical penetrations and maintain enclosure integrity. Feature → Business Impact → Application: Nickel-plated brass construction offers enhanced corrosion resistance in aggressive atmospheres, extending gland life and lowering maintenance costs. Application: Suitable for coastal refineries and mining sites where exposure to moisture and corrosive agents is common. Feature → Business Impact → Application: 1-1/4 in NPT thread and compatibility with 1.10–1.40 in armour and 1.15–1.62 in outer sheath ranges enable fast, drop-in installations with TECK armoured or non-armoured cables. Application: Field upgrades and new builds requiring standardized fittings to minimize inventory complexity. Feature → Business Impact → Application: Explosion-proof and NEC/CEC alignment plus UL certification support straight-forward approvals, reducing commissioning time and ensuring regulatory compliance for safety-critical equipment. Application: Industrial plants pursuing formal audit trails and risk-reduction programs. Feature → Business Impact → Application: Catalog and installation documentation (IF 1184, catalog page) streamline technician training and reduce the likelihood of mis-installation. Application: Maintenance crews performing inline replacements or refurbishments on existing conduit systems.

FAQs
The TMCX4140 BR NP uses a 1-1/4 in NPT thread to mate with standard enclosures and fittings. It supports both armoured barrier and non-armoured barrier configurations for TECK armoured tray cables. When selecting for a retrofit, verify armour diameter (1.10–1.40 in) and outer sheath size (1.15–1.62 in) to ensure a secure, leak-tight seal and compliant ingress protection in hazardous locations.
This gland is designed as explosion-proof and conforms to NEC/CEC standards with a NEMA 4 rating. It provides area classification for Hazardous/Classified Locations and supports Class I, Division 1 (and applicable Class II/III). Use in environments requiring robust containment of gases and dust, such as chemical plants and refineries, to maintain safety and regulatory compliance.
Yes. Its explosion-proof design, armoured barrier options, and nickel-plated brass construction make it well suited for oil & gas installations in hazardous areas. The gland supports TECK armoured tray cables and provides reliable sealing under demanding conditions, aligning with industry practice for reliable electrical penetrations in upstream and downstream facilities.
The gland aligns with NEC/CEC standards and is rated for hazardous locations (Class I, Division 1). It carries NEMA 4 protection and is supported by UL certification documentation for explosion-proof armoured barrier configurations. This combination helps streamline regulatory approvals and audit readiness for compliant installations.
Key ROI factors include durable nickel-plated brass construction reducing corrosion-related maintenance, standard 1-1/4 in NPT threading for quick fittings, and dual barrier options that simplify inventory and procurement. The availability of installation sheets and catalog pages (IF 1184 and TMCX catalog) speeds commissioning, lowers labor costs, and minimizes downtime during upgrades or new builds.
