Appleton ST-300 Liquid Tight Conduit Connector

Appleton ST-300 3-inch Straight Liquid Tight Conduit Connector terminates liquid-tight flexible conduit into an enclosure with a plain throat, using a threaded X compression connection for a secure, leak-resistant interface. Constructed from malleable iron and triple-coated (zinc electroplate, chromate conversion, epoxy powder coat) for corrosion resistance, the body measures about 3.69 inches in length and 4.38 inches in height, with a 3-inch trade size. A compression nut and ferrule bite into the conduit jacket to form a solid grip and maintain a continuous metal-to-metal ground, while a neoprene sealing gasket ensures a tight seal against oil, water, dirt, and chemicals. Engineered for vibration resistance, this ST-series connector stays secure under harsh operating conditions, and is designed for LFMC installations requiring a reliable straight connection into an enclosure. This variant is described as a liquid-tight oiltight/raintight connector with plain throat; variations in the ST family include STB-300 with an insulated throat and STN-300 with an insulated hub for different sealing and wiring needs.
