NTC75

Overview

The Appleton NTC75 is a 3/4-inch trade size compression connector designed for threadless rigid conduit and IMC applications. Constructed from zinc electroplated malleable iron, it features a non-insulated throat type with a diameter of 0.44 inches and a length of 2.44 inches. This concrete-tight fitting is engineered to secure and terminate steel EMT to knockouts and boxes, ensuring reliable electrical connections in demanding environments.

Feature Summary

• Provides concrete-tight sealing for threadless rigid conduit and IMC couplings
• Constructed from durable zinc electroplated malleable iron for corrosion resistance
• Designed specifically to secure and terminate steel EMT to knockouts

Applications

• Securing and terminating steel EMT to knockouts
• Connecting threadless rigid conduit systems
• IMC coupling applications requiring concrete-tight seals

Procurement Notes

Verify the specific catalog number variant (NTC75 vs NTC-75) against official Appleton documentation to ensure material consistency, as sources indicate both malleable iron and steel compositions. Confirm that the required finish matches the application environment, noting the zinc electroplated specification found in manufacturer data sheets.

Selection Notes

Select this component when a threadless compression connection is required for 3/4-inch rigid or IMC conduit. Ensure the installation environment supports the use of malleable iron fittings and that the concrete-tight rating meets local code requirements for the specific termination point.

Part Context

This part belongs to the Appleton NTC series of threadless compression connectors. It serves as a critical interface component in electrical raceway systems, bridging the gap between conduit runs and enclosure knockouts while maintaining environmental integrity.

Replacement Considerations

Direct substitutes include other Appleton NTC series connectors of identical trade size. Verify compatibility with existing conduit types before swapping manufacturers.
