The maximum distance between end fittings to which a straight hose assembly is to be connected is 50 inches. The minimum hose length to make such a connection should be?

• A. 50 inches
• B. 52-1/2 inches
• C. 54 inches
• D. 48 inches

Answer: (B)

When connecting a straight hose between two end fittings, you need a little extra length beyond the maximum distance to allow for the fittings to thread on and for a bit of slack so the hose isn’t pulled tight. The end-to-end distance can reach 50 inches, so the hose must be longer than that to make a reliable connection. Fifty inches would be too tight to attach the fittings. Fifty-four inches works but isn’t the smallest option that still clears the requirement. Fifty-two and a half inches provides the necessary extra clearance with the smallest amount beyond 50 inches, making it the minimum length that ensures a proper connection.
