the best sub 300 psi pump head on the market. It uses V-rings (similar design to 207V 500 psi), hence is more efficient than the T-rings and last longer without leaks in theory. Able to produce more gpm under same 200 psi condition while puts less load/wear on the motor, than the T-series (such as 112T or 114T). Just make sure the cam bearings for the motors are matched.
