Claim:
A compression plug system for plumbing, consisting of: A) a plumbing pipe ( 20 ) consisting of external wall ( 22 ), end ( 24 ) and end ( 26 ); B) a slip nut ( 30 ) consisting of external wall ( 34 ), end ( 32 ), and end ( 36 ), extending from said end ( 26 ) is an internal threaded portion ( 38 ) that extends to an internal peripheral flange ( 40 ), said internal peripheral flange ( 40 ) extends to said end ( 32 ), said internal peripheral flange ( 40 ) defines an opening ( 42 ), said external wall ( 34 ) extends approximately a same longitudinally distance as said internal threaded portion ( 38 ), said opening ( 42 ) has a third cooperative dimension to snugly receive said pipe ( 20 ) therethrough, said slip nut ( 30 ) mounted directly onto said plumbing pipe ( 20 ); C) a seal ring ( 50 ) consisting of a body ( 54 ) and an internal wall ( 58 ), angularly extending from each end of said body ( 54 ) are ledge ( 52 ) and ledge ( 56 ) of equal length, said internal wall ( 58 ) has a first cooperative dimension to receive said end ( 26 ) of said pipe ( 20 ) therethrough, said seal ring ( 50 ) is made of a malleable and ductile metal; and D) a plug ( 70 ) consisting of a head ( 74 ) having closed end ( 72 ) and an external threaded portion ( 76 ) having edge ( 82 ), extending from said head ( 74 ) is said external threaded portion ( 76 ) that extends to said edge ( 82 ), said external threaded portion ( 76 ) has a second cooperative dimension to engage with said internal threaded portion ( 38 ) of said slip nut ( 30 ), said plug ( 70 ) also has an internal wall ( 80 ) that extends from said edge ( 82 ) until an internal end ( 78 ), said plug ( 70 ) further consists of an opening ( 84 ) defining a cavity therein that reaches said internal end ( 78 ), said internal wall ( 80 ) has substantially a same diameter as said internal wall ( 58 ) of said seal ring ( 50 ), said seal ring ( 50 ) deforming as said external threaded portion ( 76 ) engages with said internal threaded portion ( 38 ) of said slip nut ( 30 ), said compression plug system for tubes and pipes ( 10 ) is assembled by mounting said slip nut ( 30 ) onto said pipe ( 20 ) by passing said opening ( 42 ) over said end ( 26 ) of said pipe ( 20 ), then sliding said seal ring ( 50 ) thereon, then mounting said plug ( 70 ) onto said pipe ( 20 ) and screwing it on with a sufficient force to compress said seal ring ( 50 ) in between said edge ( 82 ) and said internal peripheral flange ( 40 ), thus creating an impermeable seal without the aid of a sealing compound or weld, said sufficient force compresses said seal ring ( 50 ) in between said edge ( 82 ) and said internal peripheral flange ( 40 ) to fill in cavities within said internal threaded portion ( 38 ) to create said impermeable seal, further characterized in that upon removal of said plug ( 70 ), said seal ring ( 50 ) is kept in place and a faucet F may be installed onto said pipe ( 20 ), said slip nut ( 30 ), and said seal ring ( 50 ).
