1-Inch Threaded Conduit Bushing

The L.H. DOTTIE GBL100 is a zinc-plated aluminium bushing designed for 1-inch threaded conduit systems. It provides a smooth bearing surface that protects cable insulation during pulling and prevents damage at entry points. Electricians and maintenance technicians use it to finish conduit runs in commercial and industrial installations where threaded fittings are required.

Replaces Worn or Missing Bushings

This fitting replaces damaged, corroded or missing bushings on existing 1-inch threaded conduit. The upgrade is worth it when the original bushing no longer provides a smooth radius, when threads are exposed, or when a zinc-plated aluminium finish is preferred for corrosion resistance in damp or outdoor locations.

Suits Threaded Conduit Installations

It suits installers working with rigid or IMC conduit that uses 1-inch threaded hubs and need a code-compliant bushing. It is not for non-threaded conduit systems, EMT compression fittings, or applications requiring a non-metallic or insulated throat bushing.

Questions about this item

What size conduit does the 1 in threaded bushing fit?

The bushing has a 1 in threaded connection that matches standard 1 in conduit entries for a secure fit.

How do you install the zinc-plated aluminum bushing without cross-threading?

Start the bushing by hand until the threads engage fully, then tighten with a wrench; forcing it from the start is the common mistake.

When should the aluminum zinc-plated bushing be replaced?

Replace it if the zinc coating shows white corrosion, the threads are stripped, or the bushing no longer seats flush against the conduit body.
