1 in Threaded Conduit Bushing
The L.H. DOTTIE PB100 is a gray thermoplastic conduit fitting bushing with a 1 in threaded design. It provides a smooth entry point to protect wire insulation from abrasion during pulls. Electricians and maintenance technicians use it to finish conduit runs in commercial and residential projects. The non-metallic construction resists corrosion and does not require grounding.
Capacity and headroom
The 1 in trade size accommodates standard conduit bodies and fittings for typical branch-circuit wiring. Thermoplastic material handles normal pulling tension for THHN or XHHW conductors without cracking. It is not suited for high-impact industrial environments where metallic bushings are specified. Extreme cold may reduce flexibility compared to nylon alternatives.
Upgrade context
This bushing replaces worn or missing threaded inserts in existing conduit bodies during retrofits. The jump is worth it when the original metal bushing has corroded or damaged threads that cut cable jackets. It does not adapt metric or non-threaded conduit systems. Buyers needing larger trade sizes or explosion-rated fittings must select different hardware.

Questions about this item
Will the 1 in threaded thermoplastic bushing fit onto the existing metal conduit I already have installed?
The PB100 has 1 in threads designed to match standard conduit sizes, so it will screw onto compatible rigid or IMC conduit of the same trade size.
How can I confirm the bushing is seated correctly once I tighten it?
When fully threaded, the gray thermoplastic flange sits flush against the conduit end with no visible gap, and the inner shoulder protects the cable insulation from the cut edge.
Does the package include any locknuts or bushings for the other end of the run, or just this single fitting?
The box contains only the PB100 bushing; locknuts, additional bushings, and conduit lengths are sold separately.
