Arlington Industries 502L Long Bushed Conduit Nipple, 3/4"

Arlington Industries 502L Long Bushed Conduit Nipple, 3/4"

The Arlington Industries 502L Long Bushed Conduit Nipple is a 3/4" trade size fitting engineered to connect and extend conduit runs between boxes, enclosures, and equipment while safeguarding conductor insulation at the point of connection. Built with a double-chase bushed design, the 502L features factory-installed bushings on both threaded ends, eliminating the need to install separate bushings in the field during rough-in. The extended, or "Long", body length gives installers additional reach compared to a standard short conduit nipple, making it easier to bridge gaps between knockouts, hubs, and couplings in commercial and industrial raceway systems. This bushed nipple design is well suited for panelboards, junction boxes, and other enclosures where a protected, threaded connection point is required.

Key Features

• Trade Size: 3/4" trade size is sized to match standard conduit, box, and enclosure knockouts for a secure, code-compliant fit.
• Bushed (D/C) Design: Double-chase bushed construction places a smooth, factory-installed bushing on each threaded end, shielding conductor and cable insulation from abrasion as wires pass through the fitting.
• Long Length: The 502L's extended length provides greater reach than a standard short nipple, allowing it to span larger gaps between connection points without adding an extra coupling.
• Threaded Connection: Fully threaded ends allow the nipple to be secured directly into couplings, hubs, and box or enclosure knockouts for a solid mechanical and electrical connection.
• Field-Ready Installation: Because the bushings are installed at the factory, electricians can complete the connection without sourcing and fitting separate insulating bushings on the job site.
