Appleton UNILETS EY Series 1-1/4 in sealing unilet (ESUM-125) is a vertical/horizontal sealing fitting for threaded rigid metal conduit and IMC in hazardous locations. It is manufactured from malleable iron with a triple-coat finish and provides a 25% fill capacity, featuring a removable nipple that can be mounted in either hub. The unit uses tapered threads for tight joints and ground continuity, with a female-threaded X male-threaded connection; UL 886 (1203) listing (UL File E10444) and CSA C22.2 No. 30 are documented for use with threaded rigid conduit and IMC, and the design supports explosion-proof and dust-ignition-proof, rain-tight operation.
