15-Degrees x 4.5 mm Yellow Chiseling Nozzle

Stainless steel Chiseling (yellow color coded) pressure washer spray nozzle with 4.5mm orifice and 1/4 in (6.35mm) Quick Connect (QC) plug. Chiseling (yellow) QC spray nozzles have a 15 degree spray pattern for intense cleaning of unpainted hard surfaces such as grills, driveways, concrete or brick walkways, or unpainted brick or stucco. The spray gun should be directed at a 45 degree angle to the surface and be used like a scraper to remove paint, grease and dirt. The orifice size of the nozzle determines the operating pressure of the end-user's machine.  As a general rule, QC spray nozzles with 4.5mm orifices work best on pressure washers rated between 500 PSI with 1.6 GPM (low end) to 8,000 PSI with 6.4 GPM (high end). For pressure washers in-between the low end and high end, the recommended orifice size is roughly proportional from low end to high end. The spray nozzle is designed to easily connect to a 1/4 in (6.35mm) QC coupler and is ideal for quick exchange of spray nozzles and spray guns. It connects to all of the most common pressure washer equipment in the industry.
