Appleton Century Crofts EY Sealing Fitting 1/2 HAWA EYSEF50 Conduit

1/2-inch hazardous-location sealing fitting

This Appleton Century Crofts conduit fitting seals 1/2-inch trade-size IMC or RMC runs in Class I Division 1 and 2 Groups A B C D, Class II Division 1 and 2 Groups E F G and Class III areas. The iron body with silver finish provides a female NPT to male NPT transition while blocking gases vapours and flames from migrating between conduit sections. It is built for new installations that require a listed sealing point in vertical or horizontal orientation.

40-percent fill limit governs conductor capacity

The fitting carries a 40 fill rating that caps the total conductor cross-section at forty percent of the internal volume. This restriction directly limits how many wires can be pulled through the 3.800-inch overall length so installers must calculate fill before specifying cable counts. Exceeding the rating voids the hazardous-location listing and creates a fire or explosion risk in the classified zone.

Replaces non-listed couplings in classified zones

Standard couplings or unsealed junctions cannot stop flame propagation so this fitting upgrades any 1/2-inch conduit junction that now falls under NEC sealing rules. The jump is worth it when a new process area is re-classified or when an inspector flags an existing run for missing seals. It is not for buyers who need larger trade sizes or non-hazardous general-purpose connections.
