On a flexible braided line, what should you observe regarding twisting?

• A. Inspect for fraying only
• B. Check for kinks only
• C. Inspect for color changes
• D. Observe lay line for twisting

Answer: (D)

Twisting in a flexible braided line shows up when you look at the lay line—the colored marker that runs along the hose to indicate the braid orientation. If the lay line does not run straight with the length of the hose and instead twists or spirals around it, that signals twisting in the braid. This matters because twist concentrates stress, can cause the hose to kink under bending, and can shorten its service life under pressure. Fraying, kinks, or color changes are still important to note for wear or damage, but they don’t specifically reveal twist like inspecting the lay line does.
