SEAL FOR CONNECTING A TUBE TO A HOUSING MEMBER AND METHOD FOR FORMING SAME An improved fluid tight seal for connecting a tube to a housing member. A generally D-shaped opening is formed in the housing member. The opening has a flat open side where the housing member is secured to and abuts a flat surface. A groove or slot extends around the opening. The slot has enlarged corners adjacent the flat side. The tube is provided with an annular groove adjacent the end to be attached to the housing member. The tube groove receives a resilient seal which is shaped to slide into the housing member slot. The seal has corner tabs which fill the enlarged slot corners. Prior to securing the housing member to the flat surface, the seal extends slightly from the slot. When the housing member is secured to the surface, the seal is compressed to form a high pressure resilient seal between the housing member and the tube. The seal is particularly useful for connecting a compressed air outlet tube to the cylinder head of an air compressor.
