Push to connect conduit fitting with ferrule

A push to connect fitting, comprising:

• a body member having an unthreaded first end,
• a conduit comprising a conduit first end that can be axially inserted into the unthreaded first end of said body member and a circumferentially continuous metal attached conduit gripping device pre-swaged into radial compression against a first substantially cylindrical exterior surface portion of said conduit, such that an inside diameter portion of said conduit gripping device is smaller than an outside diameter of an unvarying second substantially cylindrical exterior surface portion of said conduit adjacent to the first exterior surface portion to axially fix the attached conduit gripping device on the conduit, and
• a retainer that retains said conduit first end, with said attached conduit gripping device, in place within said body member when said conduit first end, with said attached conduit gripping device, is inserted into the unthreaded first end of said body member;
• wherein said retainer prevents axial separation of said conduit from said body member after said conduit first end has been inserted into the unthreaded first end of said body member;
• wherein said retainer engages said conduit gripping device when said conduit first end has been fully inserted into the unthreaded first end of said body member;
• and
• wherein said body member comprises a tapered surface, said retainer being captured between a surface of said conduit gripping device and said tapered surface of said body member when said conduit first end has been fully inserted into the unthreaded first end of said body member.
