Cen-Tec #41741 is designed to permit the proprietary Vacu-Flo (HP Products) low volt pin style inlet valve to be converted to current industry standard vacuum inlets with pin jacks by providing the necessary components to modify the back plate that permits the change. Such a conversion permits the use to universal (corded) electric power nozzle kits, industry standard low voltage 2-wire hoses, and conventional non-electric crush proof plastic hose.
