The package includes 4 pcs M22-14 swivel and 3/8 inch plugs, 4 pcs 3/8 inch QD + M22-14 male connectors, 4 pcs 3/4 inch female connectors + 1/2 inch quick release fittings, and 4 pcs 1/2 inch plug + 3/4 inch male thread. Please note that the M22-14 swivel fitting has a 14 mm inner diameter and is not compatible with electric pressure washers that have an M22 15 mm fitting, as this may cause leaks. Two quick connector kits connect the pump outlet to the pressure washer hose or the pressure washer hose to the spray wand. Two additional quick connect kits convert the 3/4 inch thread to a quick release fitting, allowing standard 3/4 inch garden hoses to connect to the water inlet of the electric washer pump. Replacement couplers provide safe, quick connections that are easy to connect and disconnect. Suitable for maximum pressures up to 5000 PSI. The kit is designed for easy installation and removal, requiring no special tools or skills, and can be assembled in minutes. Material: Brass. Color: Gold.
