High Quality Southwire RC100 Rigid Threaded Conduit Coupling 1 Inch 50 Pack

The SOUTHWIRE RC100 is a galvanized rigid threaded conduit coupling designed to join two lengths of 1-inch threaded rigid metal conduit or IMC conduit end to end. The threaded interior accepts standard conduit threading, creating a secure, low-resistance mechanical and electrical bond between conduit sections. Electricians install this coupling in conduit runs where a continuous threaded rigid or IMC system is required. The galvanized steel construction resists corrosion, making it suitable for both indoor and outdoor conduit installations.

This coupling is commonly used in commercial and residential electrical conduit systems where rigid metal conduit or IMC is specified. It works with chase nipples and threaded connectors to bond conduit runs to electrical junction boxes, enclosures, and other raceway termination points. The threading is compatible with all standard threaded conduit connectors, allowing the RC100 to serve as a transition fitting when converting between conduit types using appropriate threaded adapters. Sold in a 50-pack for production wiring and larger installations.

Key Features

• 1-inch trade size fits standard 1-inch threaded rigid metal conduit and IMC conduit
• Galvanized steel construction provides corrosion resistance for indoor and outdoor use
• Compatible with all standard threaded conduit connectors and chase nipples
• Suitable for bonding threaded conduit to junction boxes and electrical enclosures
• 50-pack quantity supports larger conduit runs and production installations

Compatibility

Designed as an OEM-style replacement and standard fitting for 1-inch threaded rigid metal conduit and IMC conduit systems using standard NPT-style conduit threading.

Installation Notes

Installation is performed by licensed electricians in accordance with NEC Article 344 for rigid metal conduit and Article 342 for IMC. De-energize all circuits in the affected raceway before beginning conduit work. Thread both conduit ends fully into the coupling by hand, then tighten with a pipe wrench to achieve a secure, wrench-tight connection. Do not overtighten to the point of damaging threads or deforming the fitting body.
