Eaton Specification Sheet - TECK350 23
Armored TECK compatibility ensures a snug fit with TECK armored cables; this reduces field contamination and improves sealing integrity. By aligning with 3-1/2 inch NPT threads and armor range, installers cut rework time and improve first-time right installations in harsh environments. In applications such as chemical plants and offshore facilities, this translates to faster cable terminations and reliable ingress protection. Armor (min/max) and outer sheath (min/max) specifications—3.44-3.77 inches and 3.61-3.87 inches respectively—enable precise gland selection, minimizing the risk of over- or under-sizing and eliminating late-stage changes that stall projects. General purpose protection and a robust aluminum gland body deliver durable performance in demanding environments, reducing corrosion-related downtime and extending service life. The 3-1/2 inch thread size and NPT threading provide compatibility with a wide Eaton TECK accessories ecosystem, shortening procurement cycles and simplifying stocking strategies. Certification alignment with NEC/CEC, Class II Division 1, and Class III ratings supports compliance across multiple jurisdictions, while NEMA 4 protection ensures reliable operation under wash-down, dust, and moisture exposure. These features come together to deliver measurable efficiency gains, streamlined installation, and predictable maintenance needs for medium- and large-scale automation projects.

FAQs
TECK350 23 is designed for TECK armored cables and uses a 3-1/2 inch NPT gland thread. It pairs with TECK armored cable assemblies and compatible gland fittings within the Eaton Crouse-Hinds TECK family. For best results, match the armor and outer sheath ranges (3.44–3.77 in and 3.61–3.87 in) to ensure proper sealing and a field-ready connection.
TECK350 23 carries NEC/CEC standards compliance and an NEC hazardous rating of Class II, Division 1 and Class III. It is intended for Hazardous/Classified Locations and features a NEMA 4 enclosure rating, providing wash-down and moisture resistance. These certifications support safe operation in regulated industrial environments operating in hazardous zones.
The gland’s precise 3-1/2 inch NPT thread and armor-range compatibility reduce the need for field modifications, enabling faster terminations with TECK armored cables. Its aluminum body delivers durable sealing without extensive protective measures, while NEC/CEC compliance and NEMA 4 protection minimize rework due to regulatory or ingress issues, translating to reduced downtime and quicker project throughput.
Follow Eaton’s installation guidance for TECK cable fittings (IF 1417) to ensure correct assembly. Begin by selecting the gland with matching armor and outer sheath dimensions, align the TECK armored cable, and securely tighten the gland to meet applicable torque recommendations. Refer to the TECK catalog page for specific steps, torque specs, and approved sealing products.
Using TECK350 23 reduces field rework and ingress-related failures, lowering maintenance frequency in hazardous locations. The reliable aluminum gland, compatible threading, and certified protection minimize downtime, extend service life, and streamline spare-parts inventories. Over time, this leads to lower total cost of ownership and higher uptime for automation systems in challenging environments.
