Eaton 658RT Raintight Compression Connector - EMT
Part Number: 658RT
Quick Summary
The 658RT raintight compression connector from Eaton Crouse-Hinds provides a reliable EMT termination for control panels and field assemblies. Installers often confront moisture ingress, corrosion, and misalignment that threaten uptime; this connector addresses those pain points with a raintight seal, a robust steel body, and a threadless compression mechanism that speeds terminations. It complies with NEC/CEC requirements for ordinary/non-hazardous locations, and UL-listed Canadian certifications reinforce cross-border reliability in mixed environments. By combining durability with fast installation, the 658RT delivers predictable performance in harsh environments, reducing maintenance cycles and rework. For OEMs and service teams, this connector unlocks safer, faster panel builds while remaining compatible with standard EMT fittings and the broader Crouse-Hinds raintight family.

Eaton Specification Sheet - 658RT
Raintight design → Protects against moisture and corrosion, extending service life in wet or damp locations, which reduces maintenance intervals and downtime for critical equipment. Application: control panels, motor control centers, and outdoor enclosures. EMT compatibility → Simplifies field terminations with common conduit systems, enabling faster installs and fewer compatibility issues during panel upgrades. Application: new builds and retrofits in industrial facilities. Threadless compression → Eliminates cross-threading and misalignment risks, delivering consistent seals and reliable electrical integrity. Application: compact panel tops and tight spaces where quick, repeatable installations are essential. Steel construction and 3-1/2 inch trade size → Provides robust mechanical strength for demanding environments while accommodating mid-size EMT runs. Application: underground, plant floors, and proximity to vibrating machinery. Non-insulated design → Keeps electrical paths simple and compatible with standard insulation practices in ordinary locations, reducing part counts and inventory. Application: general purpose conduit fittings in non-hazardous areas. Weight and dimensions → A compact, balanced footprint (5.58 in L × 3.96 in H × 5.13 in W; 2.8 lb) helps installers manage space in crowded junction boxes and on equipment rails. Application: retrofit projects and new builds where space is at a premium. NEC/CEC compliance and certifications → Ensures installations meet widely adopted electrical codes and cross-border certification requirements, minimizing rework and accelerating approvals. Application: industrial facilities with mixed compliance needs and multi-site deployments.

FAQs
The 658RT is designed for EMT conduit with a 3-1/2 inch trade size. It uses a straight, threadless compression style that provides a secure, raintight connection suitable for standard steel EMT runs in control panels and equipment housings. For multi-size installations, pair with compatible EMT fittings from the Eaton Crouse-Hinds raintight family to maintain consistent performance.
The 658RT integrates a raintight seal within its compression connection, guarding against moisture intrusion in wet or damp environments. Use it in ordinary/non-hazardous locations such as indoor industrial facilities, weather-protected enclosures, and equipment rooms where reliable EMI/ moisture protection is required yet hazardous classifications are not present.
The 658RT adheres to NEC/CEC standards for ordinary locations and carries UL-listed Canadian certifications for EMT fittings. This combination of standards and regional certifications helps ensure regulatory compliance across projects and sites, reducing rework and accelerating approval processes.
Threadless compression eliminates the risk of cross-threading and simplifies alignment during installation. The result is faster terminations with consistent sealing pressure, reduced installer fatigue in tight spaces, and fewer callbacks due to seal failures. This is especially valuable in retrofit projects where space and time are limited.
The 658RT provides durable, moisture-resistant terminations that lower maintenance costs and downtime in non-hazardous environments. Its fast, tool-efficient compression installation reduces labor hours in both new builds and retrofits, while NEC/CEC compliance and cross-border certifications lessen rework risk and improve project throughput.
