摘要： A mechanism for attaching a gas controller to a water heater includes a shank that is longitudinally received in a spud attached to the water heater. O-rings serve to form a water tight seal between the interior surface of the spud and the exterior surface of the shank. Slots formed in the spud and a groove formed in the shank allow the two components to be axially locked to one another with the insertion of a retainer spring clip. The spring clip is readily removable to allow the two components to be separated without the destruction of any components.
