Chicago Auto Pros uses these nozzles in the shop to achieve greater pressure and release even the toughest caked-on dirt and grime from wheels, bumpers, rocker panels, and other highly-soiled areas of a vehicle.
Narrower nozzles such as this 25 degree version increase pressure; if you have a pressure washer that stands on the lower end of the pressure spectrum, reducing the angle of the spray pattern increases pressure, but will also reduce water movement (GPM). For more serious cleaning power, this is likely the nozzle you want. An angle any less than 25 degrees may be too aggressive for most automotive detailing procedures.
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.
