Pilot insert seal for a tube fitting

An apparatus for joining two conduits in fluid flow communication, the apparatus comprising:

• a fitting body with a nonlinear bore extending through the body defining a first port and a second port;
• a first fluid conduit mountable in one port of the bore in the fitting body;
• a discrete pilot insert means having first and second ends, the first end separably mounted in the other port of the bore of the fitting body, the second end for guiding alignment of a second conduit with respect to the other port of the bore of the fitting body when the second end is separably mounted in a bore of the second conduit;
• and
• at least one outwardly extending circular ridge immediately adjacent only the first end and integral with the pilot insert means for fixedly mounting the pilot insert means in the other port of the bore of the fitting body.

An apparatus for joining two conduits in fluid flow communication, the apparatus comprising:

• a fitting body with a nonlinear bore extending through the body defining a first port and a second port, wherein the bore extending through the fitting body has a reduced inner diameter between the first and second ports of the fitting body;
• a first fluid conduit mountable in one port of the bore in the fitting body;
• and
• a discrete pilot insert means having first and second ends, the first end separably mounted in the other port of the bore of the fitting body, the second end for guiding alignment of a second conduit with the other port of the bore of the fitting body when the second end is separably mounted in a bore of the second conduit.

An apparatus for interconnecting at least two fluid conduits in fluid communication with one another comprising:

• a fitting having an exterior surface, at least one passage extending through the fitting along a nonlinear path to define a first port and a second port through the external surface of the fitting at opposite ends of the passage;
• at least one pilot insert having an elongate body with an outer surface, each body having a first end engageable through one of the first and second ports into the passage, a second end operably engageable within a fluid conduit to be connected to the fitting, an aperture extending between the first and second ends of each body for placing a connected fluid conduit in fluid communication with the passage through the fitting, each body further having at least one annular ridge projecting radially outwardly from the outer surface immediately adjacent to only the first end and integral with the elongate body, the first end insertable within one of the first and second ports with a remaining portion of the body extending outwardly from the fitting;
• and
• at least one seal mountable on the outer surface of the body interposed between the at least one annular ridge and the second end for scaling the fitting with respect to the body.
