The BEX adjustable K-Ball assemblies are designed for use in multi-stage washers and spray wash machines. They are easy to install by drilling a 9/16” hole into a 1“, 1 1/4”, 1 1/2”, or 2” pipe and attaching the assembly to the pipe with a clip. The spray ball can be easily swapped out or replaced by loosening or tightening the cap, without the need for any tools. These assemblies provide a robust and reliable solution for various cleaning and spraying applications.
