Electrical Metallic Tubing

Electrical Metallic Tubing Velkor manufactures Electrical Metallic Tubing (EMT) for commercial, industrial, and residential electrical installations. Every conduit is produced from premium low-carbon steel, delivering smooth bending performance, dimensional consistency, and dependable installation efficiency. Whether you need a cost-effective standard solution or maximum corrosion protection for demanding environments, Velkor offers the right zinc coating option for your project.

EMT Connector – Set Screw Type – Zinc Die Cast

EMT Connector – Set Screw Type – Zinc Die Cast Velkor set-screw EMT connectors are die-cast from virgin zinc alloy rather than lower-grade recycled material. Maintaining a controlled alloy composition helps reduce brittleness and the risk of cracking, giving the fitting greater toughness during installation, handling and transport.

EMT Coupling – Set Screw Type – Zinc Die Cast

EMT Coupling – Set Screw Type – Zinc Die Cast Velkor zinc die-cast set-screw EMT couplings join two lengths of EMT in a straight run. Each conduit end is secured independently by its own set screw, while the one-piece zinc alloy body supports consistent dimensions and straightforward installation.

EMT Connector – Compression Type – Zinc Die Cast

EMT Connector – Compression Type – Zinc Die Cast This zinc die-cast compression connector terminates EMT conduit at an electrical box, cabinet, or enclosure. Its compression nut applies circumferential clamping around the conduit for controlled alignment, while the one-piece zinc alloy body offers dimensional consistency and a clean installation profile.

EMT Coupling – Compression Type – Zinc Die Cast

EMT Coupling – Compression Type – Zinc Die Cast Velkor zinc die-cast compression EMT couplings join two lengths of EMT using independently tightened compression nuts. The compression mechanism grips around each conduit end to support alignment without exposed set screws, while the zinc die-cast body provides a clean, compact profile.

EMT Connector – Set Screw Type – Steel

EMT Connector – Set Screw Type – Steel Designed to connect EMT conduit securely to electrical boxes and enclosures through knockout openings. Manufactured from durable steel with a zinc-plated finish for corrosion protection. The set-screw design allows quick installation and provides a secure connection in dry locations.
