A hose designated -8 has an inside diameter of which value in inches?

• A. 1/4"
• B. 3/8"
• C. 1/2"
• D. 5/8"

Answer: (C)

Dash size on hoses is a labeling system where the number after the dash roughly equals the inside diameter in inches. In typical hose sizing, the sequence goes about: -4 is 1/4", -6 is 3/8", -8 is 1/2", -10 is 5/8", and so on. So a hose designated -8 has an inside diameter of 1/2 inch. The other options correspond to smaller or larger dash sizes: 1/4" would be -4, 3/8" would be -6, and 5/8" would be -10.
