Appleton buc-75 Capped Bushing 3/4 Inch Rigid Conduit Imc

Product Description

The APPLETON buc-75 is a capped, threaded female bushing designed to terminate rigid metal conduit or IMC conduit to a box or enclosure. The body is zinc electroplated malleable iron, and the cap is polyethylene. Used with a standard locknut, this fitting provides a clean, protected conduit end at panel knockouts and enclosure entries. It measures 0.44 inches in height with a 1.25-inch diameter. Listings include UL 514B and CSA C22.2, and the fitting meets NEMA FB-1 and applicable NEC/CEC standards. It is a standard choice for electricians working in commercial and industrial conduit installations.

The buc-75 is suited for commercial and industrial applications where rigid metal conduit or IMC must be terminated at a box, panel, or enclosure. The 3/4-inch trade size fits the most common conduit run sizes in commercial wiring. The polyethylene cap protects wire insulation from abrasion at the conduit entry point, which is particularly important in pulls involving multiple conductors or larger gauge wire. This fitting is appropriate wherever code requires a bushing at conduit terminations per NEC guidelines.

Compatibility

Designed for use with 3/4-inch rigid metal conduit and IMC conduit systems. Used with a locknut to terminate conduit to a box or enclosure in commercial and industrial electrical installations.

Installation Notes

Installation is performed by licensed electricians. De-energize all circuits at the panel before working at any box or enclosure entry point. Thread the buc-75 onto the conduit end and secure with a locknut against the enclosure wall. Follow NEC Article 344 and Article 342 requirements for rigid and IMC conduit terminations, and verify that the polyethylene cap is fully seated before pulling conductors.
