Eaton 1656RT Raintight Compression Connector - Raintight
Part Number: 1656RT
Quick Summary
The Eaton 1656RT Raintight compression connector is a rugged EMT termination designed for reliable field installation in industrial environments. Electricians often struggle with moisture ingress and slow wiring when mounting raintight fittings in damp or outdoor locations. This model adheres to NEC/CEC standards and UL-listed documentation, while its Ordinary/Non-Hazardous area classification supports broad commercial use. By combining a threadless, insulated steel design with a compact 2-1/2 in trade size, it speeds installs and reduces maintenance, enabling efficient panel layouts. Engineers and contractors appreciate the straightforward integration with standard EMT fittings and common hand tools, while procurement benefits from consistent cataloging and predictable lifecycle costs. The result is a versatile solution for reliable, code-compliant terminations in challenging environments.

FAQs
To install the 1656RT, prepare the EMT conduit run and ensure the straight, compression-style coupling is clean and free of burrs. Insert the conduit, align the connector, and tighten the compression mechanism until the joint is solid and watertight. The threadless design minimizes threading steps, speeding up the process while maintaining a secure seal and mechanical integrity in non-hazardous locations.
The 1656RT is designed for NEC/CEC compliance and is listed for Ordinary/Non-Hazardous Locations. Documentation and certifications are available through UL-related pages and Eaton’s specification sheets. This alignment supports code-approved installations in commercial and industrial settings, simplifying inspection and reducing project risk when wiring with raintight EMI connectors.
Yes. The 1656RT is a raintight, insulated steel connector designed to seal against moisture in raintight installations. Its compression mechanism and threadless interface provide a robust seal suitable for damp and exterior environments, helping to prevent ingress in exposed conduit runs while maintaining structural integrity under vibration and movement.
The threadless design eliminates the need for thread engagement, reducing installation time and the risk of misalignment. It simplifies field assembly, especially in tight or crowded panels, while delivering a reliable, moisture-resistant connection. This is particularly beneficial for 2-1/2" trade-size EMT runs where space and speed are critical.
The 1656RT delivers long-term durability through insulated steel construction and raintight sealing, which minimizes corrosion and moisture-related failures. This translates to lower maintenance costs, fewer re-terminations, and extended service intervals in demanding environments, delivering a favorable total cost of ownership for industrial wiring and control systems.
