Electrical Fittings

Choose the right fittings to connect your conduit
Conduit 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, and the types of connections you need to make. In addition, electrical fittings are sized to fit the different diameters of conduit. To learn more about the different types and uses of conduit, see our Conduit Buying Guide.
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.
This buying guide will explain the different conduit fittings, so you can feel confident you’re purchasing the right fittings for your project.

Electrical Fittings — Adapters, bushings, couplings, elbows, straps, and connectors
Adapters Adapters connect different types of material or different thread sizes together. For example, an adapter might connect a run of nonmetallic conduit to a metal junction box with solvent cement on one end and threads on the other.
Bushings Bushings are 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. However threaded couplings can be screwed directly onto the end of 
        threaded conduit.
      • Nonmetallic couplings are attached to nonmetallic conduit with solvent cement.

Elbows 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, which makes it easy to pull wires through without damaging them.
Straps Straps hold conduit to the wall or joist to keep the conduit from sagging or breaking.
Connectors Connectors are used to join runs of conduit together or to 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 alongside these as well.
