    Rigid Plastic (PVC) Conduit and Fittings

    Image of System. Front orientation. Conduit and Fittings. Rigid Plastic (PVC) Conduit and Fittings.
    A nonconductive and lightweight alternative to rigid metal conduit, PVC conduit won’t break down from moisture or chemicals. It protects runs of wiring outdoors, underground, or encased in concrete. PVC cement (not included) is required when joining conduit to fittings with push-in connections.

    Connection

    Adjust these connectors to any angle from 0° to 90° to link runs or connect conduit to an electrical box. To secure them to knockouts, take off their removable ends to reveal threads.
    For 80 Pipe Schedule—With thicker walls than schedule 40, these fittings have better crush resistance to hold up where they may be struck or stepped on.

    Adjustable-Angle

    Elbow

    Protect equipment from electromagnetic interference. A color-coded wiring guide allows for quick cable termination.
    Adjustable-Angle Elbow—Plugs with an adjustable-angle elbow let you choose a 0°-90° bend angle while installing. Good when space is tight around the port, you can rotate them into 32 positions.
    Snap-On Connection—Connectors have a snap-on wire connection that pierces the insulation to eliminate the need for wire stripping.

    Standard Duct and Fittings

    Image of System. Front orientation. Exploded view. Duct and Fittings. Standard Duct and Fittings.
    Deliver air for a range of HVAC applications, including exhaust and dust collection. Our basic duct, the round shape creates smoother, more efficient airflow than rectangular and oval duct. The male end is slightly smaller than the female, so sections join without clamps or tools.
    Adjustable-Angle-Elbow Connectors (Adjusts from Straight to 90°)

    Use these connectors as an angled or straight link between pieces of duct. Adjust the shape by twisting the segments.
    Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.
    Corrosion-Resistant 304 Stainless Steel—The most corrosion-resistant metal duct we sell. It won’t rust or degrade in systems that exhaust chemical fumes or vent heat from industrial ovens and dryers.
    Lightweight Aluminum—One-third the weight of steel, aluminum ductwork is easier to handle during installation. Like galvanized steel, it resists rust in wet environments but won’t last as long.

    Liquid-Tight Flexible Plastic (LFNC-B) Conduit and Fittings

    Image of System. Front orientation. Conduit and Fittings. Liquid-Tight Flexible Plastic (LFNC-B) Conduit and Fittings.
    Block out moisture and protect wiring abrasion and crushing. This conduit has a tougher construction than LFNC-A, but it’s less resistant to vibration. For use indoors or outdoors, components are made of PVC or nylon to resist chemicals and environmental exposure. Conduit can also be buried or encased in concrete. Pair it with compatible fittings for a liquid-tight seal.
