Trade-Size 1 in Iron Sealing Fitting

This Appleton Century Crofts conduit fitting is built for hazardous-location electrical systems. It carries Class I Division 1 and 2 ratings for Groups A through D, Class II Division 1 and 2 for Groups E through G, and Class III certification. The iron body with silver finish accepts 1 in FNPT threads on both ends.

Installation Requirements and Common Issues

The fitting mounts in either horizontal or vertical conduit runs using standard 1 in IMC or RMC raceways. Thread engagement must be full and sealing compound applied per code to prevent gas, vapour or flame passage between conduit sections. Insufficient thread depth or omitted compound are the typical causes of failed inspections.

Sustained-Load Behaviour

Iron construction maintains structural integrity and seal continuity under continuous exposure to rated hazardous atmospheres. The fitting resists corrosion and mechanical stress without degradation of the flame path, ensuring long-term containment of gases, vapours or flames across the conduit system.

Questions about this item

How do I confirm the EYF-100 sealing fitting is blocking gases and flames after installation?

Verify the conduit run is sealed by performing a pressure test on the 1 in FNPT connections and inspect that the iron body shows no leaks at the horizontal or vertical orientation.

What comes with the EYF-100 and what must I supply?

The fitting itself is supplied; you must provide 1 in IMC or RMC conduit, sealing compound, and any locknuts or bushings required for the 1 in FNPT ends.

Which trade size of the EYF-100 fits my conduit run?

Choose the 1 in trade size version when your conduit system uses 1 in IMC or RMC; the overall length is 4.300 in and both ends are 1 in FNPT.
