Appleton die-cast aluminum hubs protect electrical equipment from water
October 7, 2011 | By Anthony Capkun
October 7, 2011 – Appleton, a manufacturer of hazardous-location electrical products, introduced a line of die-cast aluminum hubs designed to help engineers better protect enclosed equipment. The hubs securely connect rigid metal conduit or IMC to the threadless opening in an enclosure, providing a watertight seal and preventing water, moisture, dusts and damaging particles from entering. In addition to standard environments, both dry and wet, the hubs can be installed in hazardous industrial locations, making them suitable for chemical plants, refineries and other areas where flammable vapours, gases or combustible dusts are present. Corrosion-resistant aluminum construction is featured to ensure mechanical protection with an insulated throat to prevent wire abrasion and reduce wire-pulling effort. An integral O-ring assures a NEMA 4X watertight seal. Appleton hubs come in trade sizes ranging from 1/2-in. to 2-in., in grounding and non-grounding styles.
