3 in Threaded Conduit Connector

The L.H. DOTTIE SL300I is a 3 in threaded conduit fitting connector made from alloy steel with a zinc finish. It joins rigid or IMC conduit sections in electrical raceway systems. The component suits commercial and industrial wiring installations that require a secure, code-compliant connection point.

Threaded Joint Practical Limits

A threaded connection relies on proper engagement and torque to maintain grounding continuity and mechanical strength. Over-tightening can damage threads or conduit walls while under-tightening risks separation under vibration. The installer must verify thread compatibility and apply listed compounds where required by local inspection authority.

Alloy Steel Zinc Build Implications

Alloy steel provides high tensile strength for heavy conduit pulls and physical impact resistance. The zinc coating resists atmospheric corrosion in damp or outdoor locations. The 3 in trade size demands large wrenches and substantial clearance for assembly. Installers should plan access space accordingly.

Questions about this item

What size conduit does the SL300I 3 in fitting connect?

The SL300I fitting is a 3 in threaded connector designed to join 3 in conduit runs.

How does the alloy steel and zinc finish hold up on a job site?

Alloy steel gives the connector mechanical strength for pulling and vibration, while the zinc coating resists corrosion in damp or outdoor locations.

What thread standard does the 3 in connector use?

It uses standard NPT threads, so it mates with any 3 in threaded conduit, coupling or hub without adapters.
