There are several types of steel conduit fittings available, each designed for specific applications and requirements within electrical conduit systems. Some common types include:
Couplings: Couplings are used to join two sections of conduit together. They come in various lengths and can be either threaded or unthreaded.
Connectors: Connectors are used to join conduit to electrical boxes, enclosures, or other fittings. They may feature set screws, compression fittings, or clamps to secure the conduit in place.
Elbows: Elbows, also known as bends, allow conduit to change direction. They are available in different angles, such as 90 degrees or 45 degrees, and can be rigid or flexible depending on the application.
Tees: Tees allow conduit to branch off in different directions. They have three openings, with one inlet and two outlets, and are commonly used in junction boxes or conduit runs.
Reducers: Reducers are used to transition between conduit of different sizes. They allow for a smooth transition while maintaining electrical continuity within the conduit system.
Bushings: Bushings are used to protect wires and cables from sharp edges inside conduit fittings. They are inserted into the openings of conduit fittings to provide a smooth surface for cable installation.
Nipples: Nipples are short sections of conduit with male threads on both ends. They are used to extend conduit runs or connect conduit to junction boxes or enclosures.
Adapters: Adapters are used to connect conduit of different types or sizes. They may have different threading or attachment methods on each end to accommodate various conduit configurations.
Locknuts and Washers: Locknuts and washers are used to secure conduit fittings to enclosures or junction boxes. They provide a tight seal and prevent loosening due to vibration or movement.
Caps and Plugs: Caps and plugs are used to seal off the ends of conduit runs or fittings. They provide protection against dust, moisture, and debris when conduit openings are not in use.
