Bridgeport Fittings 431NMLT Liquid Tight Connector 3/4 in

Product Description

The BRIDGEPORT FITTINGS 431NMLT is a 3/4-inch nonmetallic liquid tight straight connector designed to join Type B nonmetallic liquid tight conduit to an electrical box or enclosure in wet and damp environments. Constructed from nylon, this connector is sunlight resistant, lightweight, and built for long-term durability in demanding field conditions. The fitting seals the conduit-to-enclosure connection using NPT threads, a knockout gasket, and an inner sealing ring, creating a reliable liquid tight assembly. Licensed electricians and electrical contractors install this type of fitting in commercial and residential applications where moisture exposure is a concern.

This connector is suited for use in wet locations as defined by the NEC. It is listed under UL File No. E9391 and rated for NEMA TYPE 2, 3, 3R, 4, 4X, and 12 enclosures, making it appropriate for outdoor, industrial, and washdown environments. BRIDGEPORT FITTINGS offers this nonmetallic liquid tight straight connector in trade sizes ranging from 3/8 inches to 2 inches, allowing selection across a range of conduit sizes on the same job.
