During hose testing, what should be marked on the hose jackets against each blank?

• A. Valve
• B. Coupling
• C. Script
• D. Clamp

Answer: (B)

Labeling the hose jackets with the word Coupling at each blank helps identify the joint between hose sections during the test. This ensures every coupling is accounted for and can be inspected for leaks or tightness under test pressure. Couplings are common failure points, so marking their locations on the jacket ties test results directly to the correct spots. Valves, scripts, or clamps aren’t the components being identified by these blanks, so they wouldn’t be the right labels.
