Ready to change your oil without a mess? Curtis Valves has been designing and manufacturing aviation valves for 80 years and are proud to introduce our NEW no mess oil drain valves. Our M12-1.5 thread valve was designed for the Polaris RZR Series but can be used on other applications with a M12-1.5 drain plug. Simply connect the activation tool to the valve, direct the drain hose into your disposal container, then push and twist the tool to lock the valve in the open position. Changing your engine oil has never been easier or cleaner! Please note: Consider valve clearance, impact protection, and intended use before installation, recommended 1.5" clearance for installed valves. MADE IN USA.
