Connects wireline surface equipment to wellhead.
The lower end of the swage connection is either threaded or flanged to fit the wellhead. The upper end of the swage is compatible to the bottom hand union of the BOP.
Standard thread sizes of swage connections carried on slickline units are: 2 and 3 inch line pipe, 2 3/8, 2 7/8 and 3 1/2 inch EUE. EUE threads have pressure ratings the same as that of standard wireline surface equipment.
