Orbit Industries PB-100 Plastic Insulating Bushing 1 Inch

Product Description

The ORBIT INDUSTRIES PB-100 is a threaded plastic insulating bushing designed to protect wire insulation at the termination point of rigid metal conduit (RMC) and intermediate metal conduit (IMC). Sized for 1 inch trade size conduit, the bushing threads directly onto the conduit end and presents a smooth, rounded interior surface that prevents abrasion damage as conductors are pulled through. It is constructed from high-impact polypropylene rated to 105 degrees C, making it suitable for a range of commercial and residential electrical installations. Electricians rely on this fitting to meet conductor protection requirements at conduit terminations.

The PB-100 is used wherever threaded RMC or IMC terminates at a panel, junction box, or equipment enclosure and bare conduit threads would otherwise contact the wire jacket. Typical applications include branch circuit conduit runs in commercial buildings, industrial facilities, and residential service entrances. The bushing is appropriate for installations where NEC Article 300 requires protection of conductors at conduit ends.

Key Features

• Fits 1 inch trade size threaded rigid metal conduit and IMC
• High-impact polypropylene construction rated to 105 degrees C
• Smoothly rounded interior surface reduces wire jacket abrasion during pull-through
• Threads directly onto conduit end — no tools required for installation
• Lightweight, non-conductive material eliminates grounding concerns at the bushing itself

Compatibility

Designed as a direct-thread replacement-style insulating bushing for 1 inch trade size threaded rigid metal conduit and IMC installations.

Installation Notes

This bushing is installed by licensed electricians as part of conduit termination work. De-energize all circuits in the enclosure before pulling conductors or making terminations. Hand-thread the bushing fully onto the conduit end before the conduit is secured to the enclosure knockout. Verify compliance with NEC conductor protection requirements at conduit terminations prior to final inspection.
