The PRO-SOURCE 4019010128 is an engine cleaning blow gun kit designed to direct compressed air at engine components, greasy assemblies, and hard-to-reach surfaces during maintenance and cleaning operations. The kit accepts a 1/4 inch inlet connection and is rated for a maximum working pressure of 120 psi, making it compatible with standard shop compressor setups. This type of tool is commonly used by automotive technicians, fleet maintenance crews, and general shop mechanics who need a controlled, high-velocity air stream to clear debris, dry components, or prep surfaces before inspection or reassembly.
Engine cleaning blow guns are standard equipment in automotive repair bays, fleet shops, and industrial maintenance facilities. The 1/4 inch inlet is the most common quick-connect size in North American shops, allowing this kit to drop into existing air supply lines without adapters in most cases. It is suited for blowing down engine bays, clearing cooling fins, removing chips from machined parts, and drying washed components prior to service.
Designed as a direct-fit replacement or add-on tool for shop air systems operating at up to 120 psi with standard 1/4 inch compressed air supply lines.
Installation is performed by connecting the 1/4 inch inlet to the shop air supply line using the appropriate quick-connect fitting. Always verify that the supply line pressure does not exceed the 120 psi maximum working pressure rating before use. Eye protection and hearing protection should be worn when operating compressed air blow guns, in accordance with OSHA general industry standards. Inspect the inlet connection and any included extensions for cracks or wear before each use.
