Comp Cams TOOL, AIR OPERATED VALVE HOLDER 14/18mm

Air Operated Valve Holder

The Air Operated Valve Holder is the perfect accessory when it's time to replace valve springs or valve stem seals. Simply thread one end into the spark plug tube and attach the other end to an air compressor. Air pressure will keep the valve from falling into the cylinder, allowing you to easily work without taking the cylinder head off. With a heavy-duty 12" flexible hose and convenient two-step fitting for both 14mm and 18mm threads, access to both the spark plug hole and air supply is never a problem.
