发明名称 Method of installing captive type spark plug gasket with low profile locking tabs
摘要 An improved locking type spark plug gasket in which the locking lugs are of such configuration as to lie within the vertical height of the sealing folds of the gasket. The configuration especially adapts it to receive a synthetic resinous coating applied after manufacture, and facilitates installation on that type of spark plug having an undercut area at the base of the threaded shank portion thereof.
