Killark ENY-1 RMC Sealing Conduit

This Killark ENY-1 sealing conduit fits hazardous-location electrical systems that require Class I Division 1 and 2 protection. The 1/2 inch threaded aluminum body carries ratings for Groups A through D and Class II Groups E through G. Installers use it to seal vertical or horizontal rigid metal conduit runs in industrial environments. Gray zinc-plated finish resists corrosion in harsh settings.

Threaded 1/2 in FNPT ends for rigid conduit

Female-to-female threads connect directly to 1/2 inch RMC without adapters, simplifying the fitting count in a conduit assembly. The 3 15/16 inch overall length keeps the seal compact inside enclosures or junction boxes. Aluminum construction reduces weight compared to steel alternatives while maintaining the required hazardous-location ratings. Horizontal and vertical orientation flexibility suits varied routing plans.

Aluminum body dissipates heat in sealed runs

The metal housing conducts warmth away from conductor insulation during normal load conditions. No moving parts or fan means silent operation in noise-sensitive plants. Zinc plating adds a barrier against moisture and chemical exposure that could degrade the seal over time. The fitting draws no power and adds negligible resistance to the circuit.

Questions about this item

Does the 1/2 in trade size limit the number of conductors I can pull through the sealing fitting?

The fitting accepts 1/2 in RMC conduit; conductor fill is governed by NEC tables for that trade size and the sealing compound volume required for Class I Division 1 locations.

Will the aluminum body run hot or create noise when installed in a continuously energized hazardous-area circuit?

The aluminum zinc-plated body is a passive sealing fitting with no moving parts or electrical load, so it produces no audible noise and its temperature rise is negligible under normal operation.

What conduit and sealing compound must I already have on hand to complete the installation?

You need 1/2 in rigid metal conduit (RMC) with female NPT threads and a listed sealing compound approved for Class I Division 1 Groups A, B, C, D and Class II Groups E, F, G.
