Superior Quality Construction --: Crafted from premium stainless steel, our pressure washer adapters are designed for longevity and resistance to rust. They effectively handle high working pressures of up to 5000 PSI and can withstand temperatures up to 300°F, ensuring reliable performance under demanding conditions. Important Compatibility Note --: Please be aware that the inner diameter of the M22-14 swivel is 14mm. This adapter is specifically designed for 14mm connections; using a 15mm fitting may result in leaks. We strongly advise against using the M22 15mm connector with high-pressure washers. User-Friendly Design --: The 3/8" M22 quick installation connector easily connects to your pressure washer pump. It allows for simple conversion of 3/4" threads into quick-release fittings, enabling seamless attachment of any 3/4" standard garden hose to the power washer's water inlet.
