The M22-to-Quick-Connect adapter is a convenient fitting for pressure washer setups. It features a female M22 swivel nut on one end and a 3/8″ quick-connect socket on the other, allowing garden hoses to be quickly clicked into place instead of being screwed on manually.
Constructed from solid brass with a rubberized grip, the adapter offers durability, corrosion resistance, and ease of hand-tightening. It is important to note that M22 fittings come in two pin sizes (14mm and 15mm), and matching the correct size is critical to prevent leaks.
Safety Note: This adapter is rated for 300 PSI and should only be used on the inlet side of the pressure washer (where the garden hose connects). It must not be used on the outlet side, where pressures range from 1,500–4,000+ PSI, as this could cause failure or injury.
