1/2" RIDGID THREADED COUPLING

🧾 What it is:

A small cylindrical metal fitting with internal threads on both ends. It screws onto the ends of rigid conduit to connect two straight pipe sections together.

🔧 What it’s used for:

• Joining two pieces of 1/2" rigid steel conduit (RMC)
• Joining IMC (Intermediate Metal Conduit)
• Extending conduit runs in electrical systems
• Maintaining a continuous grounded metal raceway

Typical applications:

• Industrial electrical wiring
• Outdoor conduit runs
• Service entrances
• Equipment feeds

⚙️ Key features:

• Threaded both ends (NPSM straight threads)
• Usually galvanized steel for corrosion resistance
• Provides a strong mechanical and electrical bond
• Often UL listed for electrical conduit systems
• Designed for rigid conduit systems (not EMT or flex unless adapted)
