Conduit Fitting Choices

Choose the right electrical conduit fittings to connect conduit and your devices

Conduit Fitting Choices - Buying Guide

Conduit fittings, also called electrical fittings, are used to connect runs of conduit together or to connect conduit to electrical devices. The types of fittings you use will depend on whether you’re using metallic or non-metallic conduit, the types of connections you need to make, and the diameter of the conduit you’re connecting.

This guide will explain the different conduit fittings, so you can feel confident you’re purchasing the right fittings for your project.

Tip: Local building and electrical codes regulate the type of conduit and fittings that can be used in specific applications. Check with your local building inspector before beginning a project and be sure to obtain any required permits. When your work is complete, always have it inspected for compliance with local codes and to ensure that it has been safely installed.

Electrical Fittings

Select from conduit fittings such as adapters, bushings, couplings, elbows, straps, and connectors.

Fitting type Use

Adapters

Connect different types of material or different thread sizes together

Bushings

Inserted into the ends of metal conduit to keep the sharp edges from damaging the wires that run through the conduit

Couplings

  • Connect runs of the same type of conduit to create a longer straight line.
  • Metallic couplings are generally attached to metallic conduit with set screws or with compression
  • Threaded couplings can be screwed directly onto the end of threaded conduit
  • Nonmetallic couplings are attached to nonmetallic conduit with solvent cement

Elbows

  • Join runs of the same type of conduit together to turn corners or to change direction in a gentle sweeping curve, rather than a sharp right angle
  • Makes it easy to pull wires through without damaging them

Straps

Hold conduit to the wall or joist to keep conduit from sagging or breaking

Connectors

Join runs of conduit together or join conduit to outlet boxes, load centers or other devices


Additional fittings such as reducers, offset couplings, and other various specialty fittings are also available, depending on your needs.
