Dust-tight straight cord connector

The Hubbell 073031211 is a straight aluminium cord connector with a galvanised-steel mesh strain relief. It accepts a single cable with a diameter between .97 in and 1.25 in and threads into a 1-1/4 in MNPT box opening. The insulated body meets CSA and UL standards.

Replaces open bushings

Use this connector when an existing gland lacks dust sealing or pull-out protection. The jump is worth it on installations where conduit vibration or cable movement could loosen a plain fitting, or where inspectors require a listed dust-tight termination.

Sustained load behaviour

Under continuous tension the mesh strain relief distributes force along the cable jacket rather than concentrating it at the gland nut. The aluminium body and galvanised steel relief resist corrosion in damp locations, while the insulated throat prevents conductor abrasion during long-term thermal cycling.

Questions about this item

What cord diameter range does the 1-1/4 in MNPT straight connector accept?

The connector accepts cords from 0.97 in to 1.25 in diameter. The 1-1/4 in MNPT box connection threads directly into a compatible hub or enclosure.

How do you install the mesh strain relief without damaging the cord jacket?

Slide the aluminium body onto the cord, then the galvanised steel mesh grip. Tighten the gland nut by hand plus one-half turn with a wrench; over-tightening crushes the jacket and reduces strain relief.

When should the galvanised steel mesh grip be replaced?

Replace the mesh grip if individual wires are broken, the weave is flattened, or corrosion appears on the galvanised coating. Inspect during routine conduit checks or after any sharp pull event.
