Application & fit

The Appleton Century Crofts EYSEF125 is a sealing fitting for IMC and RMC conduit systems rated for hazardous locations. It provides a 1 1/4 in trade-size connection with FNPT x MNPT threaded ends to isolate conduit sections in Class I, II and III environments. Installers use it where gases, vapours or flames must not pass between portions of a conduit run.

Installation & durability

The iron body with powder-coated silver finish resists corrosion in demanding industrial settings. Threaded ends allow direct assembly to compatible conduit without additional adapters. The 5 1/2 in overall length fits standard conduit spacing while maintaining the hazardous-location seal integrity required by code.

Deciding specification

The fitting carries hazardous-location ratings for Class I Division 1 and 2 Groups B, C, D, Class II Division 1 and 2 Groups E, F, G and Class III. Buyers who need a different trade size, a non-threaded connection or a fitting not rated for these specific hazard groups cannot use this part.

Questions about this item

How do I install the EYSEF125 sealing fitting onto 1-1/4 in IMC conduit without damaging the threads?

Apply thread sealant to the 1-1/4 FNPT female end, hand-tighten onto the conduit, then use a strap wrench for the final turn to avoid cracking the iron body.

What maintenance does the EYSEF125 require after installation in a Class I Division 1 area?

Inspect the powder-coated iron body annually for corrosion or coating damage; replace the fitting if the silver finish shows pitting or the threads no longer seal gases.

At what point does the EYSEF125 reach its thermal limit during continuous exposure to hot gases in a hazardous location?

The iron construction and hazardous-location rating contain flames and vapours indefinitely; the fitting itself has no thermal cut-off, so the conduit system's cable insulation rating becomes the limiting factor.
