HUB and HUBG types watertigh hubs are used to terminate runs of threaded conduit through the wall of a electrical enclosure. They are available with or without ground screw. Ideal for use in pharmaceutical plants, chemical, petrochemical and food processing plants, pulp and paper factories and marine platforms. Resistant to a wide variety of chemicals.
80-84 (Shore A Durometer).
400 Volts/Mil at 60 cycles.
1000 hours (Atlas wet UV chamber).
200% min.
Polyvinyl chloride has a crystallization temperature of 5° F (-15° C).
PVC coating will burn if exposed to continuous flame or heat above 400°F (204°C).
Prolonged exposure to temperatures greater than 200°F (93°C) or fire may cause the PVC coating to release emissions potentially hazardous to the health of those exposed to them.
