Bridgeport Fittings 152-DC Threaded Hub 3/4 Inches

Product Description

The BRIDGEPORT FITTINGS 152-DC is a 3/4-inch die cast zinc insulated threaded hub designed to secure threaded rigid service entrance conduit to a box or enclosure. The hub features a BUNA-N sealing ring that completely encircles the knockout, creating a concrete-tight seal that blocks moisture, dust, and other contaminants from entering the enclosure. An insulated throat rated to 105 degrees C protects conductors at the point of entry. Listed for use with both aluminum and steel rigid conduit, this fitting is suited for service entrance and general conduit termination work performed by licensed electricians.

The 152-DC is used in residential and commercial electrical installations where rigid conduit must terminate cleanly at a panel, junction box, or enclosure. The concrete-tight BUNA-N seal makes it appropriate for installations where moisture infiltration is a concern, including exterior enclosures and service entrance applications. It is compatible with standard 3/4-inch threaded rigid conduit fittings and installs directly into standard knockout openings of that size.

Key Features

• BUNA-N sealing ring creates a concrete-tight seal around the knockout opening
• Insulated throat rated to 105 degrees C protects conductors at entry point
• Die cast zinc construction for durability across most indoor and outdoor environments
• Listed for use with both aluminum and steel rigid conduit
• Meets NEMA Standard FB-1 and UL Standard UL-514B

Compatibility

Listed for use with aluminum and steel rigid conduit in 3/4-inch trade size. Designed as an OEM-style threaded hub for standard 3/4-inch knockout openings on boxes and enclosures.

Installation Notes

Installation is performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits and confirm power is off at the source before beginning conduit termination work. Thread the hub securely into the knockout opening and ensure the BUNA-N sealing ring seats fully and evenly around the knockout edge to maintain the concrete-tight seal. Do not overtighten in a way that deforms the sealing ring or damages the zinc body.
