FUNKS NAMENDO Check valve removing tool. Handy tool made for removing the check valve for Coleman Lanterns. Less chances of damaging the threads or stripping the screwhead of the check valve! Our secret is the Japanese inspired double lock system. Have you ever had trouble using a stock wrench when replacing a check valve? With Namendo, changing the check valve won't be a hassle anymore. This specially designed check valve removing tool makes a huge difference. NAMENDO is designed to lock into the check valve for easy removal. In the past if you use the wrong amount of force, irreversible damage was done on the thread or the screwhead of the check valve. But thanks to NAMENDO, the connecting rod firmly connects to the check valve, so it can be removed without damaging the check valve. All Namendo products are manufactured in Japan. The parts are machined one by one by experienced craftsmen with high precision to fit properly into the soft brass check valve without damage.
