Product Description

The BRIDGEPORT FITTINGS Threaded Coupling is a self-aligning three-piece threaded coupling for RMC conduit, with a 3-inch trade size and 3 3/4-inch overall length. This non-insulated iron coupling, model 1128-RT, is designed for joining rigid metal conduit in industrial electrical systems.

Frequently Asked Questions

What is a BRIDGEPORT FITTINGS three-piece threaded coupling used for?

This coupling joins two lengths of rigid metal conduit (RMC) in industrial electrical systems. Its three-piece self-aligning design simplifies alignment during installation, making it suitable for conduit runs in factories, power plants, and commercial buildings where secure, grounded connections are required.

What are the specifications of the BRIDGEPORT FITTINGS 1128-RT coupling?

The 1128-RT is a three-piece iron threaded coupling for RMC conduit. It has a 3-inch trade size, 3 3/4-inch overall length, and is non-insulated. The self-aligning design helps maintain conduit alignment during assembly. It is manufactured by BRIDGEPORT FITTINGS.

Where to buy BRIDGEPORT FITTINGS threaded couplings worldwide?
