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. The M22-14 swivel fitting has a 14mm inner diameter and is not compatible with electric pressure washers that have a M22 15mm fitting, as this may cause leaks. Two quick connector kits allow connection between the pump outlet and the pressure washer hose or between the pressure washer hose and the spray wand. Two additional quick connect kits convert the 3/4 inch thread to a quick release fitting, enabling standard 3/4 inch garden hoses to connect to the water inlet of the electric washer pump. Replacement couplers provide safe and secure connections that are easy to attach and detach. Suitable for maximum pressures up to 5000 PSI. The kit is designed for easy installation and removal without the need for special tools or technical skills, and can be assembled in minutes.
