A conduit fitting that prevents the ingress of cutting fluids is marked as?

The term that describes a conduit fitting designed to prevent the ingress of cutting fluids is "liquidtight." This designation indicates that the fitting is constructed to create a seal that blocks liquids from entering the conduit, which is essential in environments where fluids may be present. Liquidtight fittings are specifically used in applications where exposure to moisture and cutting fluids could interfere with electrical connections or compromise safety.

This is particularly important in industrial settings, such as workshops or factories, where cutting fluids are prevalent during machining processes. Using a conduit fitting marked as liquidtight ensures that the internal wiring remains protected from potential damage caused by these fluids, contributing to the longevity and reliability of the electrical system. The construction of these fittings typically includes a design that includes gaskets or other sealing mechanisms that enhance their watertight properties.

The other choices do not specifically refer to this characteristic. For instance, while "waterproof" might imply a barrier against water, "liquidtight" is the more precise term for preventing various types of liquids, not just water. "Flexible" refers to the material's ability to bend without breaking, and "heavy duty" generally indicates a more robust construction but does not inherently guarantee protection against liquids.
