Eaton 1659DC EMT compression connector - Threadless
Part Number: 1659DC
Quick Summary
1659DC EMT compression connector by Eaton is designed to join EMT conduits in rugged industrial electrical installations. Installers often struggle with misalignment, moisture ingress, and slow hand-tight connections when using thread-style fittings in harsh environments. This connector complies with NEC/CEC standards and is rated for Ordinary/Non-Hazardous Locations, with UL certifications available for both US and Canada. By combining a zinc die-cast, insulated body with a threadless compression mechanism, it delivers reliable performance, reduces field rework, and supports rapid, compliant wiring in control panels, machines, and equipment. End users appreciate the consistent fit and reduced part count that helps maintain uptime and project schedules.

FAQs
The 1659DC is specified for a 4 inch trade size EMT conduit in a straight, compression, threadless configuration. It is designed for standard EMT installations in ordinary/non-hazardous locations per NEC/CEC. For other conduit sizes, consult Eaton’s catalog and use appropriate compatible fittings to ensure a secure, code-compliant join.
The threadless compression design eliminates threaded connections, reducing misalignment risk and torque variability. This results in faster terminations and more consistent contact pressure, improving electrical reliability while simplifying field staff training. Applications in control panels and machinery wiring benefit from quicker wiring and fewer call-backs due to loose fittings.
Yes. The 1659DC is rated for Ordinary/Non-Hazardous Locations and complies with NEC/CEC standards. Its insulated, zinc die-cast construction supports durable terminations in typical indoor control panels, enclosures, and equipment racks, while UL certification options help satisfy regulatory requirements for US and Canadian deployments.
The connector adheres to NEC/CEC standards and carries an Ordinary/Non-Hazardous Location classification. UL certification documents are available for North American and Canadian compliance, and Eaton’s product pages provide links to UL listings and catalog references for the 1659DC, along with the EMI/UL data as applicable.
The 1659DC reduces installation time through a simple, threadless compression design and protects terminations with an insulated, zinc die-cast body, lowering maintenance costs from moisture-related corrosion and rework. Its compatibility with standard EMT fittings simplifies inventory, accelerates commissioning, and improves long-term reliability in machines and panels.
