EYM-50 IMC Sealing Conduit

The Appleton EYM-50 is a 1/2 inch threaded iron sealing fitting finished in electro zinc. It connects 1/2 inch FNPT to 1/2 inch MNPT ends with an overall length of 3 1/2 inches. The fitting carries hazardous location ratings for Class I, Division 1 and 2, Groups A through D, Class II, Division 1 and 2, Groups E, F, G, and Class III. It is designed for electricians and maintenance crews sealing IMC or RMC conduit systems in hazardous environments.

Upgrade from unsealed couplings

Standard conduit couplings do not block the passage of gases, vapours or flames between conduit sections. This sealing fitting replaces them where codes require a positive barrier in vertical or horizontal runs. The jump is worth it when the installation falls under the listed Class and Division ratings and the conduit trade size is 1/2 inch. It is not for systems using larger trade sizes or conduit types other than IMC or RMC.

Limits of threaded iron conduit seals

The fitting relies on threaded engagement and a sealing compound that must be applied correctly to maintain the hazardous location rating. It only fits 1/2 inch trade size IMC or RMC conduit with matching FNPT and MNPT threads. The iron body with electro zinc finish provides mechanical strength but does not protect against all corrosive atmospheres. Buyers who need different thread genders, larger conduit sizes, or non-hazardous area fittings cannot use this model.

Questions about this item

What thread size and type does the EYM-50 need for mounting?

It fits 1/2 in FNPT female and 1/2 in MNPT male threads, matching the trade size of the IMC or RMC conduit it seals.

How is the sealing fitting installed and what step is often missed?

Thread the male end into the conduit run and the female end onto the next section, then apply sealing compound inside to block gases, vapours and flames — skipping the compound defeats the hazardous-location rating.

What maintenance or replacement will the EYM-50 need over time?

The electro-zinc iron body resists corrosion, but inspect the threads and sealing compound periodically; replace the fitting if the coating is damaged or the compound has cracked.
