The main types of Steel Conduit Fittings can be broadly categorized based on their function and shape within a conduit system. Here are some of the primary types:
Couplings and Connectors:
Rigid Conduit Couplings: Used to join two lengths of rigid steel conduit together. They often include a threaded design for secure fastening.
Flexible Conduit Connectors: Allow for a flexible connection between conduit sections, providing movement capabilities in systems that require flexibility.
Elbows and Bends:
90-Degree Elbows: Provide a right-angle turn in the conduit run.
45-Degree Elbows: Used for a more gradual turn, often in tighter spaces or to accommodate specific installation requirements.
Long Radius Bends: Have a longer radius curve, which can help with wire or cable management within the conduit.
Outlets and Boxes:
Conduit Outlet Boxes: Provide access points to the interior of the conduit system, allowing for wire connections or branch circuits.
Conduit Outlet Fittings: Attached to the box, they allow for wires or cables to enter or exit the conduit system.
Hubs and Adapters:
Threaded Hubs: Attach to the end of a conduit to provide a threaded connection point for other fittings or equipment.
Adapters: Used to connect different types of conduits or to transition from one size to another.
Caps and Plugs:
End Caps: Seal the end of a conduit, preventing ingress of dust, dirt, or moisture.
Plugs: Inserted into unused outlets or holes in conduit boxes to maintain a sealed environment.
Supports and Brackets:
Conduit Straps: Used to secure the conduit to a wall, ceiling, or other structural support.
Hangers and Brackets: Provide support for the conduit, helping to maintain its position and prevent sagging.
Specialty Fittings:
Expansion Joints: Allow for movement in the conduit system due to thermal expansion or contraction.
Transition Fittings: Designed to connect different materials or types of conduits, such as steel to PVC.
Each type of fitting serves a specific purpose within the conduit system, ensuring proper routing, support, and access to the wires or cables within. The choice of fitting type depends on the specific application, installation environment, and conduit material used.
