Chicago Auto Pros uses these nozzles in the shop to pre-rinse vehicles that have little soiling, and to rinse vehicles after a wash. This is a gentler nozzle that maximizes water flow to make for a more pleasant rinsing experience with a pressure washer.
Wide-angle nozzles such as this 40 degree version generally decrease pressure and increase water flow. If you have a pressure washer that stands on the higher end of the pressure spectrum, increasing the angle of the spray pattern reduces pressure (PSI), but will also increase the effective water movement (GPM). For general maintenance washing and rinsing purposes, this is likely the nozzle you want.
MTM Hydro's Stainless QC Nozzles offer superior performance and extended life as a result of a refined manufacturing process. This premium nozzle is 100% tested for orifice accuracy and degree setting so you never have to worry about using an inaccurate nozzle. In addition to the meticulous testing process, MTM Hydro nozzles are manufactured with striations in the stainless steel to securely hold the pressed head of the nozzle and eliminate the possibility of the colored head falling off, as with competing models.
All MTM Hydro nozzles are laser etched along the neck with degree and size of the nozzle. For reference: 25045 translates to 25° size 4.5 orifice.
