Overview
The Appleton straight connector 3/4″ is a liquidtight connector designed to join liquidtight flexible metal conduit to knockout openings in enclosures and junction boxes. Built with zinc-plated steel construction, this straight connector provides a reliable, watertight seal suitable for food processing, machinery enclosures, industrial control panels, and other demanding applications where moisture and contamination must be excluded.
Key Features
- Zinc-plated steel construction resists corrosion in moist environments
- Liquidtight seal protects connections from oil, water, dirt, dust, and fumes
- Straight-through design for easy axial insertion into conduit
- UL-listed for industrial and commercial installations
- Metallic connectors held tight to more than 4× UL pull-out requirement
- Neoprene sealing grommet provides strain relief on flexible conduit
