4100SET-16B are a full set of size 1 inch wet line couplings. Wet line couplings are hydraulic couplings used on trucks and trailers to connect and disconnect hydraulic lines without causing oil spills. They consist of male and female halves, which are connected by a locking mechanism or threaded collar. Wet line couplings allow for quick and easy connection and disconnection of hydraulic hoses, saving time and reducing downtime during maintenance and repair.

Designed for most industrial fluid applications, this coupling is ideal for oil well equipment, sand and salt spreaders, as well as live bed trailers and other heavy duty applications.
