Orbit Industries WH-150 Watertight Hub 1-1/2 Inch

Product Description

The ORBIT INDUSTRIES WH-150 is a watertight conduit hub designed to connect and bond threaded rigid or IMC conduit to threaded openings in electrical boxes and enclosures. Constructed from die-cast zinc, it delivers rugged metallic durability suited for both wet and dry location installations. The hub includes an insulated throat that protects wire insulation during pull-through and reduces pulling effort. An O-ring seal provides a rain-tight connection at the box or enclosure entry point. Licensed electricians install this fitting as part of a code-compliant conduit system where moisture ingress must be controlled.

The WH-150 is suited for use in residential and commercial electrical installations where conduit enters enclosures, junction boxes, or panels exposed to wet or damp conditions. Typical applications include outdoor panels, service entrances, industrial enclosures, and any installation where a watertight conduit termination is required at a threaded knockout. The 1-1/2 inch trade size fits standard threaded rigid metal conduit and IMC of the same trade size.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits and verify power is off before working on any enclosure or panel. Thread the hub fully into the knockout opening and ensure the O-ring seats flush against the enclosure surface for a proper rain-tight seal. Do not overtighten to the point of distorting the O-ring or damaging the hub threads.
