PVC-Coated Conduit Bodies and Fittings
Unique sealing ring and groove design for optimum performance!
OCAL-BLUE® Double-Coat and Stainless Steel Hubs
• Captive sealing ring won’t buckle or slip during installation and provides a complete
360° seal — even when conduit isn’t perpendicular to the enclosure
• Hexagonal/splined body and locknut enable fast and easy installation
• Insulated throat molded from 105° C-rated thermoplastic, UL94V0 flammability rated
• Sharper and deeper teeth provide a more penetrating bite for improved bonding to the enclosure
• Zinc or copper-free aluminum with a nominal .040" (40 mil) PVC coating bonded
to exterior — in blue, white, gray or custom colors
