Cut Sheet

Sealing Fittings Explosion-Proof, Dust-Ignition-Proof
Application
• Limits flames and/or explosions to area within electrical
system where they originate
• Limits pressure piling
• Required by NEC for conduit systems in hazardous
locations 18" from an enclosure housing a heat
producing or arcing device; on 2" and larger system
that enters an enclosure containing splices; wherever
conduit leaves a Class I, Division I area and enters
a non-hazardous area
Features
• Copper-free* aluminum provides increased
corrosion resistance
• Precision cast and machined surfaces permit
safer wire pulling
