Appleton ESUF200 Rigid Condulet Fitting 1 Inch

Appleton ESUF200 1 in Rigid Condulet Fitting is a sealing Unilet (UNILET) designed for use with threaded rigid metal conduit (RMC) and IMC to seal around conduit penetrations as they enter enclosures. As part of the ESUF/ESUM family, these fittings prevent the passage of gases, vapors, or flames between sections of a conduit system and can be installed for vertical or horizontal runs near enclosure boundaries in classified spaces. The body is cast from malleable iron and finished with a triple-coated process, with finish options including zinc electroplate, chromate, or epoxy powder coat, to enhance durability in harsh environments. Specifically sized for the 1-inch conduit designation, ESUF200 aligns with Appleton’s sealing fittings aimed at protecting conduits at enclosure interfaces and ensuring a ground-continuous joint through accurately tapped, tapered threads, which helps maintain reliability in explosive or dust-ignition‑proof applications (Class I, Division 1 and 2).
