Sealing Fitting for Hazardous Locations

The Appleton Century Crofts EYM-150 is a threaded iron conduit sealing fitting rated for Class I, Division 1 and 2, Groups B, C, D, Class II, Division 1 and 2, Groups E, F, G, and Class III hazardous areas. It prevents the passage of gases, vapors, or flames between sections of a conduit system. The fitting connects 1-1/2 inch FNPT to 1-1/2 inch MNPT ends and is compatible with IMC and RMC conduit types.

Performance Under Sustained Conditions

The iron construction provides mechanical durability in demanding industrial environments where the fitting remains continuously exposed to hazardous atmospheres. Its sealing function is maintained under constant pressure from contained gases or vapors without degradation. The 5-1/2 inch overall length accommodates the necessary sealing compound volume for a reliable, long-term barrier in vertical or horizontal installations.

Upgrade and Replacement Context

This fitting replaces worn or non-compliant seals in existing 1-1/2 inch trade size IMC or RMC conduit runs where hazardous location ratings are required. The jump is worth it when a conduit system must meet Class I, II, or III division standards and the current fitting lacks the proper hazardous location certification or has compromised sealing integrity. It is not suited for non-threaded conduit systems or installations requiring larger trade sizes.

Questions about this item

Does the EYM-150 sealing fitting generate any heat or noise when installed in a conduit run that operates continuously?

No, the EYM-150 is a passive iron sealing fitting with no moving parts or electrical components, so it produces no heat or noise during continuous operation.

What conduit and threading must already be in place for the EYM-150 to connect properly?

You need 1-1/2 in IMC or RMC conduit with a female NPT thread on one side and a male NPT thread on the other to match the fitting's 1-1/2 in FNPT x 1-1/2 in MNPT ends.

Will the EYM-150 maintain its hazardous-location seal when paired with older iron conduit and fittings already on site?

Yes, the fitting is rated for Class I Division 1 and 2, Groups B, C, D and Class II Division 1 and 2, Groups E, F, G, so it preserves the seal when joined to existing compatible iron conduit systems.
