Plumbing hookup kit

A plumbing coupling assembly for connecting a fluid connection having a male threaded fitting of a particular size and type that cooperates with a mating threaded coupling nut, said coupling nut including an apertured wall, said hookup kit comprising:

• a flexible tubing;
• a generally cylindrical terminal means being secured at least at one end of said tubing, said terminal means having a securing portion for securing said terminal means to said tubing and a mounting portion that is adapted to be extended through said apertured wall, said mounting portion having an annular recess adjacent its tip and at least one annular collar displaced from said tip;
• and
• a sealing sleeve means having a bore extending therethrough so that said sealing sleeve means can be positioned on said mounting portion, said sealing sleeve means having a barrel portion, a first sloping wall extending from one side of said barrel portion, a second sloping wall extending from an opposite side of said barrel portion and resilient finger means extending from said second sloping wall that are adapted to cooperate with said recess to maintain said sealing sleeve means on said terminal means between said tip and said collar whereby upon the securing of said coupling nut on said corresponding fitting, said sealing sleeve means engages said mounting portion of said terminal means and said second sloping wall of said sealing sleeve means engages said fitting to provide a fluid tight hookup between said terminal means and said fitting.

A plumbing coupling assembly for connecting a fluid connection having a male threaded fitting of a particular size and type that cooperates with a mating threaded coupling nut, said coupling nut including an apertured wall, said hookup kit comprising:

• a flexible tubing;
• a generally cylindrical terminal means being secured at least at one end of said tubing, said terminal means having a securing portion for securing said terminal means to said tubing and a mounting portion that is adapted to be extended through said apertured wall, said mounting portion having an annular recess defined between a pair of annular collars;
• a pair of split locking ring means adapted to be mounted together on said mounting means to form a locking ring means, each of said split locking ring means having an inner annular projection to be disposed in said recess of said mounting portion, an inner annular groove to receive one of said collars and an outer annular groove;
• and
• a relative flexible sealing ring means having a bore therethrough so as to be positioned on said mounting portion, said sealing ring means having a annular inner projection that is adapted to be disposed in said outer annular groove to maintain said split locking ring means on said mounting portions whereby upon the securing of said coupling nut on said corresponding fitting, said sealing ring means engages said mounting portion of said terminal means and said fitting to provide a fluid tight hookup between said terminal means and said fitting.

A plumbing hookup kit for establishing a fluid tight connection to at least three different fluid connections, each of which said fluid connections including a male threaded fitting of a particular size and type that cooperates with a mating threaded coupling nut, each said coupling nut including an apertured wall, said hookup kit comprising:

• a flexible tubing;
• at least one generally cylindrical terminal means, said terminal means being secured at an end of said tubing and having a securing portion for securing said terminal means to said tubing and a mounting portion that is adapted to be extended through said apertured wall;
• and
• sealing means adapted to be positioned on said mounting portion of said terminal means, said sealing means being adapted to connect said terminal means with a particular one of said different fluid connections in a fluid tight relationship when said coupling nut is secured on said fitting of said particular one of said different fluid connection, said sealing means including a brass ferrule adapted to be positioned on said mounting means for providing a fluid tight connection to one of said at least three different fluid connections, a sealing sleeve adapted to be retained on said mounting means by resilient finger means for providing a fluid tight connection to a second of said at least three different fluid connections and split locking ring means adapted to be retained on said mounting portion by a sealing ring means for providing a fluid tight connection to a third of said at least three different fluid connections.
