Eaton 653YELLOW EMT Connector - Threadless, 1-1/4" NEC/CEC
Part Number: 653YELLOW
Quick Summary
653YELLOW is an EMT compression connector for secure, reliable conduit joins in industrial environments. When panel space is tight and vibration is common, installers need fast, tool-free connections that won't loosen over time. This Eaton component supports NEC/CEC compliance and UL certification for ordinary/non-hazardous locations, helping teams meet code requirements with confidence. Color-coded yellow finishes, steel construction, and a threadless compression design streamline inventory, reduce rework, and improve reliability across control panels and conduit runs. By standardizing on the 1-1/4 inch trade size, engineers can simplify procurement and accelerate project timelines while maintaining electrical integrity. For maintenance teams, consistent fittings mean fewer surprises during panel upgrades and future expansions.

FAQs
653YELLOW is designed for standard EMT conduit and matches a 1-1/4 inch trade size, straight, compression, threadless configuration. It works with steel conduit and is non-insulated, making it a straightforward choice for most indoor panels. The color-coding aids identification, and the absence of threads reduces tool requirements during terminations.
The connector aligns with NEC/CEC installation standards and is suitable for Ordinary/Non-Hazardous locations. UL certification references for EMT fittings support compliance, and the product documentation confirms the size and code alignment. This combination helps ensure code-compliant, safer installations and smoother inspections.
Yes. The threadless compression mechanism retains the connector securely under vibration, reducing loosening risks compared with threaded fittings. Steel construction adds rigidity, and the compression fit maintains conductor integrity. For machines with frequent starts, stops, or shock loads, this minimizes maintenance and rework while delivering reliable performance in non-hazardous areas.
Leverage the threadless compression to avoid threading and torque challenges. The 1-1/4 inch size matches common EMT runs, and color-coded yellow helps crews identify fittings quickly. With a straight, non-insulated design, fewer parts are needed, enabling faster panel fills and easier field replacements, which translates to shorter project timelines.
Faster terminations and simpler inventories translate to lower labor costs and shorter project timelines. The NEC/CEC compliance reduces rework risk, while durable steel construction minimizes future maintenance. Across large installations, the threadless, compression approach improves panel reliability and reduces downtime, yielding measurable lifecycle savings.
