Choosing the size
Quick-connect sizes go by the outside diameter of the male tube end. Measure the tube just behind the raised bead: 1/4" is about 6.4 mm, 5/16" about 7.9 mm (often called 8 mm), 3/8" about 9.5 mm (often called 10 mm) and 1/2" 12.7 mm. A female quick-connect only fits the male size it is made for.
