What is the indication for liquidtight fittings approved for use with LFNC-B?

Liquidtight fittings approved for use with LFNC-B (Liquidtight Flexible Nonmetallic Conduit, Type B) are specifically designed to accommodate the unique requirements of this type of conduit. LFNC-B is characterized by its ability to resist moisture and various chemicals, making it suitable for damp or wet environments. The liquidtight fittings ensure a proper seal, preventing the ingress of water and other contaminants, thereby protecting the wiring and ensuring the safe and reliable operation of the electrical system.

These fittings are constructed to align with the performance characteristics of LFNC-B, ensuring compatibility and compliance with safety standards. Their approval signifies that they have undergone rigorous testing and meet the necessary specifications for strength, durability, and resistance to environmental factors.

In comparison, the other conduit types mentioned, such as LFNC-A, LFNC-C, and LFNC-D, designate different material properties, installation contexts, or flexibility levels. Therefore, the fittings meant for LFNC-B specifically cater to its intended applications, making the choice of liquidtight fittings approved for LFNC-B the most appropriate and correct answer in this context.
