Husqvarna 505 74 87-01  CBL CLAMP 3/8"

The purpose of the Clamp is to bind, constrict, or press two or more parts together as a fastening device. Types of clamps include spring clamps, wire clamps, or band (worm gear) clamps. Clamps aid in sealing hoses and fuel lines, as well as binding coils, levers, cables, air filters, and mufflers. Home users can check the tightness of their clamps in their annual tune-up. If you encounter leaking fluid from your equipment, first verify if the problem may be limited to bad hose clamps.
