EYSR Retrofit Sealing Fittings

Crouse-Hinds series EYSR retrofit sealing fittings are installed in rigid metal conduit systems in Class I, Division 2 hazardous locations to replace installed Eaton’s Crouse-Hinds series EYS or EYD sealing fittings.  EYSRs allow the replacement to be done without disassembly of the conduit system, and they can be installed in vertical or horizontal positions, indoors or outdoors.

As with all sealing fittings, EYSRs restrict the passage of gases, vapors or flames from one portion of the electrical installation to another, limit explosions to the sealed off enclosure, and limit pre-compression or “pressure piling” in conduit systems.

When installed with a Crouse-Hinds series ECD15 drain, EYSR sealing fittings can also prevent accumulation of water in the conduit system.
