Compression-style straight connectors eliminate threading steps, enabling rapid terminations with a dedicated tool. This translates to shorter panel build times, reduced labor costs, and more predictable results in high-volume assemblies. In practice, engineers appreciate consistent electrical contact and fewer field adjustments when using 653BLACK in automated equipment. The steel construction with a black, non-insulated finish delivers robust durability and corrosion resistance suitable for ordinary locations. Its threadless design minimizes galling and cross-threading risks, while maintaining secure, vibration-resistant connections in active electrical panels. The 1-1/4 inch trade size and 1.81 inch length provide a compact fit for dense conduit runs, allowing cleaner routing in control cabinets and switchgear enclosures. EMT compatibility ensures broad adoption across standard installations, reducing part variety and simplifying inventory. Availability of UL listings, NEC/CEC compliance, and Eaton catalog resources further support engineering validation and procurement workflows. CAD drawings and catalogs streamline design review, favoring faster project approvals and reduced design risk for industrial automation projects.

FAQs
The 653BLACK is a straight, compression-type EMT connector designed for a 1-1/4 inch trade size. It is threadless and non-insulated, intended for steel EMT conduits in ordinary locations. It requires a compatible compression tool and is ideal for quick, reliable terminations in control panels, switchgear, and enclosures.
Compression fittings like the 653BLACK eliminate threading and set-screw steps, enabling faster terminations with a dedicated compression tool. This reduces handling time, minimizes the risk of cross-threading, and yields more consistent electrical contact, which is especially beneficial in high-volume panel builds and tight electrical spaces.
The 653BLACK is rated for Ordinary/Non-Hazardous Locations under NEC/CEC standards. It is not specified for hazardous environments. For such applications, select fittings with appropriate hazardous-location ratings and verify compatibility with local codes and UL listings.
It adheres to NEC/CEC standards for ordinary locations and is accompanied by UL certification resources for both the US and Canada. These certifications support compliance documentation and regulatory acceptance in typical industrial facilities and help simplify procurement and quality assurance processes.
Eaton provides design resources including a 3D CAD drawing package, an EMT catalog page, and a specification sheet. These assets help verify dimensions, weight, and rating, support accurate modeling in assemblies, and facilitate faster approvals during the engineering and procurement stages.
