Cut sections (1ft Length, priced per foot) is sold by the foot, so ordering a quantity of 1 will be a 1 foot (or 12 inch) section of air line.

Continuous (1piece, priced per inch) is a continuous length, so orders must be for the number of inches you want the full length to be. (To convert feet to inches, multiply the number of feet by 12. Example, if you need 4 feet in length: 4x12=48, so you would set your order quantity to 48. )
