Frequently Asked Questions

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

This self-aligning three-piece threaded coupling is used to join and align sections of RMC (rigid metal conduit) in industrial electrical installations. It provides a secure, threaded connection for conduit runs in commercial buildings, factories, and infrastructure projects where conduit must be mechanically coupled without insulation.

What are the specifications of the BRIDGEPORT FITTINGS 1127-RT threaded coupling?

The BRIDGEPORT FITTINGS 1127-RT is a three-piece iron threaded coupling with a 2 1/2 in trade size and 3 7/16 in overall length. It is non-insulated and compatible with RMC conduit. The manufacturer part number is 1127-RT. This coupling is designed for rigid metal conduit systems requiring a self-aligning threaded joint.

How to install a BRIDGEPORT FITTINGS three-piece threaded coupling?

To install, thread the coupling onto the first RMC conduit end, then align and thread the second conduit into the opposite end. Tighten the center ring to lock the joint. Use a pipe wrench on the coupling flats; avoid over-tightening to prevent thread damage. Ensure threads are clean and apply a suitable conduit thread compound for a secure, grounded connection.
