Designed for use on portable oxygen tanks, allows the user to easily open and close the tanks used in oxygen therapy. An essential tool for anyone involved in oxygen therapy. Unlike other wrenches / keys that are made of plastic, our heavy duty wrench is made entirely of die-cast zinc. The strong and durable construction means it won’t break or deform when opening and closing oxygen tanks.
