This pack is not an upgrade to HI-FLO PACK, and it is not HYDRO-BLADE II+ - it is replacement first generation 3D printed HYDRO-BLADE-2 rinse bars only for REACH-iT BRUSHES with round end-caps.
We highly recommend upgrading to HI-FLO, as it doubles the flow rate to the brush, resulting in a much more powerful jetstream. HYDRO-BLADE-2 has 36 x 1mm (1/25") jetstreams, double the cross-section area of HYDRO-BLADE (ORIGINAL v3). This means they require more flowrate. If you have pumps and loads of pressure (remember, we need flow rate, not pressure), then you can make them work, however, be notified that all our brushes we sell with HYDRO-BLADE-2 and HYDRO-BLADE II+ are modified for HI-FLO TUBE.
HYDRO-BLADE II is not available for 20" and 24" at this time, as we evaluate the design and advantage for the larger brushes.
HYDRO-BLADE II+ is currently only available with HI-FLO, or by PM to existing HI-FLO owners. If you have a tank/pump system, we can also supply by custom order.
