When two enclosures or junction boxes need to connect back-to-back through a wall or partition, a zinc conduit nipple is the right tool — and this one delivers a clean, code-compliant solution for rigid IMC applications. Cast from zinc die for dimensional accuracy and durable thread engagement, this cULus-listed 1/2" zinc conduit nipple creates a concentric, flush-fitting connection that keeps conduit runs aligned and watertight in damp-rated environments. The zinc die-cast body resists corrosion while maintaining the thread integrity required for secure IMC terminations. Suitable for residential, commercial, and industrial installations, it fits back-to-back box mounting, wall-fed entry points, and through-block conduit runs without modification.

The 3/4" zinc conduit nipple is the go-to fitting for back-to-back junction box connections on standard commercial IMC runs — and this zinc die-cast version is built with the precision and durability that trade work demands. Rated cULus and engineered for rigid IMC conduit, it delivers a concentric, flush connection between two enclosures that holds alignment and keeps the run code-compliant in damp-rated installations. The zinc die-cast construction maintains tight thread tolerance and resists the corrosion that comes with mechanical room and exterior-adjacent applications. At 3/4" trade size, it serves the most common IMC runs in commercial work.
