Electrical Conduit Fittings

Match the fitting type (EMT, rigid, flexible, PVC, or liquid-tight) to your conduit material and the application environment, and choose fittings sized to the conduit nominal trade size; check manufacturer tables for thread type and hub dimensions when connecting different systems

Common materials include steel (galvanized or zinc-plated) for indoor and general use, stainless steel for corrosive or marine environments, and PVC or plastic for non-metallic conduit; select finishes rated for outdoor exposure or chemical contact as required

Look for listings and markings that indicate compliance with applicable standards (for example UL, CSA, or IEC equivalencies) and confirm voltage, temperature, and conduit type ratings to ensure the fitting meets code and safety requirements

Reusing fittings is acceptable if they are undamaged, maintain threads and seals, and retain required corrosion protection; replace fittings that are deformed, stripped, corroded, or include one-time-use seals or gaskets

Basic tools include pipe wrenches or conduit wrenches sized to the fitting, thread sealant or tape for threaded connections when specified, knockout punches for boxes, and torque guidance if provided by the manufacturer; use personal protective equipment when cutting or threading conduit

Periodically inspect fittings for looseness, corrosion, cracked seals, or compromised insulation barriers, tighten or replace fittings showing wear, and ensure any accessible seals remain intact to preserve moisture and corrosion protection

Individual small fittings typically range from low-cost options under $10 up to more specialized or heavy-duty fittings that can be $20–$100 or higher; kits and larger assemblies generally cost more depending on material and complexity
