Castair Replacement Industrial V-Belt — Section A, 67" Length (3-A67)
The Castair 3-A67 is the longest Section A belt in the standard Castair replacement belt range, at 67 inches outside circumference. This length fits compressor configurations with the widest center-to-center distance between motor and pump pulleys in the A-belt-drive family. If your compressor originally used a 67-inch A-section belt, this is your replacement — do not substitute a shorter or longer belt expecting to make it work with pulley adjustment alone.
