  1. Conduit fitting

    The fitting connects or terminates the selected conduit system. Match retention, interface, sealing and required bonding.

  2. Conduit hub

    The mounting hub joins conduit to the enclosure. Verify the full system, mounting face and electrical continuity.

  3. EMTThis term

    The tube outline illustrates the product form. Its nominal designation does not establish an actual outside diameter or suitable fitting.

  4. Flexible metal conduit

    Interlocked metal can accommodate permitted movement. Verify bend, termination and bonding requirements for the actual conduit.

  5. LFMC / LFNC

    These liquidtight conduit families have different constructions. Check the exact system and whether a metallic bonding path exists.

  6. Nominal trade size

    A trade size is a system designation. Use the actual conduit dimensions and matching fitting specification.

  7. Anti-short bushing

    The insulating sleeve separates conductors from a cut metallic armour edge. It addresses edge protection rather than replacing a gland seal.

A rigid tube, flexible metallic structure, jacketed system and mounting hub use different connection methods. An edge-protection bushing addresses a specific sharp-edge risk.

Conceptual sections without trade sizes. Conduit family, fittings, bonding, cable protection and liquid-ingress duties must be confirmed as a complete system.
