       27 . An apparatus comprising: 
 a body with a first end and a second end, the second end having a mating surface with an annular protrusion extending therefrom;    an adapter having an axial groove with an outward edge to contact the mating surface, the axial groove being dimensioned so that the outward edge contacts the annular protrusion while the body is coupled to the adapter;    a seal ring disposed within the axial groove; and    a tensioner to couple the body to the adapter.    
   
   
       28 . The apparatus of  claim 27 , wherein the seal ring comprises virgin polytetrafluoroethylene.  
   
   
       29 . The apparatus of  claim 27 , wherein the mating surface of the body contacts the adapter when coupled to form a primary metal to metal seal.  
   
   
       30 . The apparatus of  claim 29 , wherein the seal ring forms a secondary seal when the body and the adapter are coupled.  
   
   
       31 . The apparatus of  claim 30 , wherein the secondary seal comprises a first extruded portion and a second extruded portion.  
   
   
       32 . The apparatus of  claim 31 , wherein the axial groove is radially modified by the annular protrusion.  
   
   
       33 . The apparatus of  claim 29 , wherein the primary metal to metal seal comprises a sliding seal.  
   
   
       34 . The apparatus of  claim 27 , wherein the outward edge and the annular protrusion are deformed when the body is coupled to the adapter.  
   
   
       35 . An apparatus comprising: 
 an adapter to couple to a corresponding body;    a tensioner adapted around the adapter to mate with the corresponding body; and    a conduit coupled to the adapter, the conduit having a tensioner retainer protruding from a portion thereof to maintain the tensioner in substantial axial communication between the tension retainer and the adapter.    
   
   
       36 . The apparatus of  claim 35 , wherein the tension retainer comprises a cylindrical protrusion on the conduit.  
   
   
       37 . The apparatus of  claim 35 , wherein the cylindrical protrusion is crimped on the conduit.  
   
   
       38 . The apparatus of  claim 35 , wherein the tensioner retainer to maintain the substantial axial communication prior to mating of the tensioner and the corresponding body.  
   
   
       39 . An apparatus comprising: 
 an adapter;    a tensioner adapted around the adapter; and    a conduit coupled to the adapter, the conduit having a tensioner retainer extending from a portion thereof to maintain the tensioner in substantial axial communication with the adapter and the conduit.    
   
   
       40 . The apparatus of  claim 39 , wherein the adapter has an axial groove dimensioned to receive a seal ring.  
   
   
       41 . The apparatus of  claim 40 , further comprising a body with a first end and a second end, the second end having an annular protrusion extending therefrom.  
   
   
       42 . The apparatus of  claim 41 , wherein the second end of the body contacts the adapter when coupled by the tensioner to form a primary metal to metal seal.  
   
   
       43 . The apparatus of  claim 42 , wherein the seal ring forms a secondary seal when the body and the adapter are coupled.
