Eaton 1658RT Compression Connector - Raintight
Part Number: 1658RT
Quick Summary
Eaton 1658RT compression connector provides raintight EMT terminations for reliable panel wiring in industrial settings. Designers often wrestle with fittings that resist moisture, dust, and corrosion while meeting NEC/CEC requirements. This connector aligns with NEC/CEC standards and is supported by certification reports for Ordinary/Non-Hazardous Locations and Canadian use. In practice, the 1658RT reduces field rework and installation time through a straightforward, threadless compression mechanism and a robust steel body. By combining raintight protection with an insulated design, it supports safer connectivity in control panels, equipment rooms, and outdoor enclosures while streamlining procurement and stock-keeping with a single, versatile EMT fitting.

FAQs
To install the 1658RT, prepare the EMT conduit ends, insert the conduit into the connector’s compression area, and tighten the compression mechanism until a secure seal is formed. Since this is a threadless design, alignment is straightforward, reducing cross-threading risk. Ensure the area is clean and dry to maximize the raintight performance. Use compatible conduit stops and fittings for a complete EMT system.
Key specs include a 3-1/2 inch trade size, straight connector configuration, EMT conduit type, steel material, insulated insulator, and a threadless compression style. It is rated for raintight service and intended for ordinary/non-hazardous locations under NEC/CEC standards. The dimensions (approximately 5.67 in length, 4.14 in height, and 5.04 in width) support mid-size conduit terminations.
Yes. The 1658RT is designed as a raintight, insulated connector suitable for ordinary or non-hazardous locations. Its raintight feature protects terminations from moisture and dust, making it appropriate for outdoor enclosures or damp indoor environments where reliable conduit termination is critical.
The 1658RT adheres to NEC/CEC standards and is supported by certification reports for ordinary/non-hazardous locations. The product is part of the Eaton Crouse-Hinds raintight family, with Canadian certification documents available for reference. This combination aids in regulatory approvals and project documentation in North American markets.
The 1658RT reduces maintenance by delivering durable raintight protection and a quick, threadless installation that minimizes rework and field errors. Its robust steel construction resists wear in demanding environments, lowering replacement frequency and warranty claims. By simplifying procurement (a single, versatile EMT fitting), it also shortens project timelines and lowers overall lifecycle costs.
