*This unit does not have threads in the hose barb for metering tips. By eliminating the threads, the ID of the hose barb could be made
larger to accommodate the maximum chemical draw. You can cut down the maximum draw by using the 61-9K metering tip kit. The
metering tips will fit loosely in the hose barb but the intake tube will hold them in place.
