Appleton announced today it has expanded its watertight aluminum die cast hubs to include trade sizes 2-1/2″ to 4″, giving electricians more choice in connecting rigid conduit or IMC to larger enclosure openings.
UL listed and CSA certified, these corrosion resistant hubs prevent wire abrasion with an insulated throat that is rated to 105°C. A captive BUNA-N O-Ring provides a watertight seal (NEMA 4X), while smooth, accurately tapped threads yield easier insulation, a process that is further enhanced by the Hub’s faster wrenching profile. NPT threads fit standard knockouts.
Designed for use indoors or outdoors, Appleton’s Watertight Hubs meet NEC requirements for hazardous locations (Class I, Div. 2; Class II, Div. 1 & 2; Class III) found in chemical and petrochemical plants, refineries, pulp and paper processing plants, and other areas where flammable vapors, gases or combustible dusts are present. Rugged, corrosion-resistant metallic construction ensures mechanical protection in the most demanding industrial environments.
