         4 . The plunger lift lubricator of  claim 1 , wherein the pipe connector profile of the outlet pipe connector is a thread profile that conforms to a 14.5 degree Acme profile. 
     
     
         5 . The plunger lift lubricator of  claim 1 , wherein the top thread profile conforms to a 14.5 degree Acme profile; and
 the pipe connector profile of the outlet pipe connector is a thread profile that conforms to a 14.5 degree Acme profile.   
     
     
         6 . The plunger lift lubricator of  claim 1 , comprising a spring housing threadedly connected to the top thread profile. 
     
     
         7 . The plunger lift lubricator of  claim 1 , further comprising a spring housing haying a lower end disposed within a top passage of the top thread profile; and
 a connector attached to the housing and threadedly connected to the top thread profile.   
     
     
         8 . The plunger lift lubricator of  claim 7 , wherein the outlet pipe connector comprises a liner disposed in the lubricator bore; and
 an annular passage between the liner and an inner wall of the lubricator bore.   
     
     
         9 . The plunger lift lubricator of  claim 7 , wherein the pipe connector profile of the outlet pipe connector is a flange profile. 
     
     
         10 . The plunger lift lubricator of  claim 7 , wherein the outlet pipe connector comprises a liner disposed in the lubricator bore; and
 an annular passage between the liner and an inner wall of the lubricator bore.   
     
     
         11 . The plunger lift lubricator of  claim 1 , wherein the lower lubricator section is formed of a single piece of material including the top thread profile, the bottom flange profile, and the outlet pipe connector and the pipe connector profile. 
     
     
         12 . The plunger lift lubricator of  claim 11 , wherein the outlet pipe connector comprises a liner disposed in the lubricator bore; and
 an annular passage between the liner and an inner wall of the lubricator bore.   
     
     
         13 . The plunger lift lubricator of  claim 11 , where the pipe connector profile is flange profile. 
     
     
         14 . The plunger lift lubricator of  claim 11 , further comprising a spring housing having a lower end disposed within a top passage of the top thread profile; and
 a connector attached to the housing and threadedly connected to the top thread profile.   
     
     
         15 . The plunger lift lubricator of  claim 14 , wherein the outlet pipe connector comprises a liner disposed in the lubricator bore; and
 an annular passage between the liner and an inner wall of the lubricator bore.   
     
     
         16 . The plunger lift lubricator of  claim 1 , wherein the lower lubricator section comprises:
 the outlet pipe connector formed of a single piece of material, wherein the vertical throughbore extends between a top surface and a bottom surface;   a flow body formed of a single piece of material having a vertical throughbore forming a portion of the lubricator bore and extending from the bottom flange profile to a top flange profile that is connected to the bottom surface of the outlet pipe connector; and   an adaptor formed of a single piece of material having a vertical throughbore forming a portion of the lubricator bore extending from the top thread profile to a bottom flange profile that is connected to the top surface of the outlet pipe connector.   
     
     
         17 . The plunger lift lubricator of  claim 16 , wherein the outlet pipe connector comprises a liner disposed in the lubricator bore; and
 an annular passage between the liner and an inner wall of the lubricator bore.   
     
     
         18 . The plunger lift lubricator of  claim 16 , further comprising a spring housing having a lower end disposed within a top passage of the top thread profile; and
 a connector attached to the housing and threadedly connected to the top thread profile.   
     
     
         19 . The plunger lift lubricator of  claim 16 , wherein the pipe connector profile of the outlet pipe connector is a flange profile.
