Industrial RB300-125 RE Bearings and Bushings

Appleton RB300-125 reducing bushing is a threaded, malleable-iron conduit reducer that transitions from a 3-inch trade-size opening to 1-1/4 inches. Finished in zinc electroplate for corrosion resistance, this HazLoc-rated bushing is designed for use with rigid conduit and IMC in hazardous locations and is UL-listed and CSA-approved for safety compliance. Part of Appleton's RB reducing-bushing family, the 3 × 1-1/4 in model provides a compact, durable interface that helps maintain a protected, sealed conduit run in industrial environments such as chemical plants, oil and gas facilities, and other settings where conduit fittings must withstand dust, moisture, and exposure to harsh conditions. The RB300-125 combines robust mechanical strength with standard threaded installation, ensuring compatibility with Appleton locking nuts and fittings and with other RB-series reducers across sizes. This specific model emphasizes a reliable, field-friendly transition between conduit sizes without additional adapters, delivering a dependable solution for code-compliant conduit reductions in demanding installations.
