MTM Hydro 3/8" High Pressure Ball Valve Plated Brass DN10 Ball Valve for Hoses. DN10 is one of the best pressure washer ball valves we have found in the industry. These ball valves are great for commercial and residential cleaning because they allow you to disconnect and switch from your surface cleaner to your wand without turning off your pressure washer.
These pressure washer ball valves are great time savers and in our own personal experience the DN10 ball valves have lasted longer than any other we have tested. This is one of the most popular ball valves in the industry.
