BRIDGEPORT FITTINGS

Bridgeport Fittings, a brand with a long history in the electrical industry, specializes in the manufacture of conduit fittings and accessories for electrical raceway systems. The product line encompasses a wide range of components designed for use with rigid metal conduit (RMC), intermediate metal conduit (IMC), and electrical metallic tubing (EMT). Core product families include grounding locknuts, grounding bushings (both solid and split), grounding lug hubs, and self-aligning three-piece threaded couplings. These fittings are typically constructed from materials such as brass, steel (with tin electro-plating or zinc plating), iron, and aluminum, selected for mechanical strength and corrosion resistance. Key technical specifications across the range include trade sizes from 3/4 inch to 4 inches, NPT thread types, and overall lengths that vary by fitting type and size. Many components are rated for use in grounded electrical systems, with insulated options available for specific applications. Bridgeport Fittings products are commonly applied in commercial, industrial, and infrastructure electrical installations where secure conduit connections and reliable grounding paths are required. 3G Electric stocks over 70 SKUs of Bridgeport Fittings, providing plant engineers, maintenance managers, and procurement specialists with a consistent supply of these components. Each SKU is accompanied by datasheets containing dimensional data, material specifications, and applicable standards, enabling technical buyers to verify compatibility with existing raceway systems. 3G Electric supports global logistics for these products, ensuring that Bridgeport Fittings components are available for projects worldwide without geographic restrictions on procurement.

Common Applications

  • Industrial electrical grounding — Bridgeport Fittings grounding lug hubs (MCH-075) for RMC/IMC conduit connections in manufacturing plants.
  • Commercial conduit installation — Bridgeport Fittings self-aligning three-piece threaded couplings (1122-RT) for aligning RMC runs in tight spaces.
  • Substation grounding — Bridgeport Fittings split grounding bushings (SGBS-38840) for bonding large-diameter conduit to enclosures.
  • Process facility wiring — Bridgeport Fittings grounding locknuts (162-G) for securing IMC or threaded rigid conduit in corrosive environments.
  • Infrastructure projects — Bridgeport Fittings three-piece couplings (1130-RT) for 4-inch RMC connections in tunnels or utility vaults.

Frequently asked questions

Common questions about BRIDGEPORT FITTINGS from 3G Electric.

What materials are Bridgeport Fittings grounding lug hubs typically made from?

Bridgeport Fittings grounding lug hubs, such as the MCH-075 and MCH-100 models, are constructed from brass. Brass is selected for its electrical conductivity, corrosion resistance, and mechanical durability in environments where grounding connections must maintain low resistance over time. These hubs are non-insulated and feature NPT threads for secure attachment to RMC or IMC conduit.

Are Bridgeport Fittings split grounding bushings available with insulation?

Yes, Bridgeport Fittings offers split grounding bushings with insulation. For example, the SGBS-38840 model is a steel split bushing with a tin electro-plated and zinc plated finish, and it is insulated. The insulation provides an additional layer of electrical isolation between the bushing and the enclosure, which can be required in certain grounding configurations to prevent unintended current paths.

What trade sizes are available for Bridgeport Fittings self-aligning three-piece threaded couplings?

Bridgeport Fittings self-aligning three-piece threaded couplings are available in a range of trade sizes. Examples from the product line include 3/4 inch (MPN 1122-RT), 1 inch (MPN 1123-RT), 2 1/2 inch (MPN 1127-RT), and 4 inch (MPN 1130-RT). These couplings are made of iron and are designed for use with RMC, providing a secure, aligned connection that simplifies installation in tight spaces.

Do Bridgeport Fittings grounding locknuts come in insulated versions?

Based on the product specifications available, Bridgeport Fittings grounding locknuts, such as the set screw coupling model 162-G, are listed as non-insulated. This component is designed for use with IMC or threaded rigid conduit and is constructed from zinc or aluminum with a tin-plated finish. For applications requiring insulated locknuts, buyers should verify specific model availability through the product datasheets.

What is the thread type used on Bridgeport Fittings grounding lug hubs?

Bridgeport Fittings grounding lug hubs, including models MCH-075 and MCH-100, use NPT (National Pipe Thread) threads. For the 3/4 inch trade size hub, the thread size is 3/4-14 NPT, and for the 1 inch trade size, it is 1-11 1/2 NPT. NPT threads provide a tapered, pressure-tight seal suitable for conduit connections in electrical systems.
