Dust-Tight Cord Connector 0.43–0.54 in

The Hubbell dust-tight cord connector accepts a single cable with an outer diameter between .43 and .54 inches. It threads into a 1/2 in MNPT box entry and uses a straight aluminium body with a galvanised steel mesh strain relief. The fitting is CSA and UL listed for indoor or outdoor conduit runs.

Environmental sealing and mechanical load

The dust-tight rating prevents particulate ingress while the external mesh grip distributes pulling force over a five-inch length. Aluminium construction resists corrosion without adding significant weight to the conduit assembly. No insulation is present, so the connector relies on the enclosure’s own grounding path.

Mesh strain relief and compliance marks

The supplied galvanised steel mesh reduces cable fatigue at the entry point without requiring separate clamps. CSA and UL markings confirm the part meets North American safety standards for dust-tight applications. Installers gain a listed component that integrates directly into standard 1/2 in threaded hubs.

Questions about this item

How do I install the Hubbell 073031202 dust tight cord connector and what step is often missed?

Thread the 1/2 in MNPT box connection into the enclosure, pass the cord through the .43 to .54 in range, and tighten the mesh strain relief; the step often missed is fully securing the galvanized steel mesh to prevent cord pull-out.

What maintenance or replacement will the Hubbell 073031202 connector need over time?

Inspect the aluminum body and galvanized steel mesh strain relief periodically for corrosion or deformation; replace the unit if the mesh grip loosens or the cord diameter falls outside the .43 to .54 in range.

What limit appears first on the Hubbell 073031202 connector during sustained use?

The dust tight seal and mesh strain relief are rated for CSA and UL standards; the practical limit is the .43 to .54 in cord diameter range, beyond which the connector cannot maintain its grip or seal.
