The field-proven E-4™ wireline pressure setting assembly is used to set any electric line set product including bridge plugs, cement retainers, retainer production packers, and other wireline set tools.In all applications where an E-4 assembly is used, a Model B™ or other appropriate wireline adapter kit will be required.

The pressure required is built up through a slow-set power charge, (Product Family No. H43766), or a standard power charge, (Product Family No. H43764). For specifics on all power charges and igniters refer to Slow-Set Power Charge, Standard Power Charge, Secondary Igniter, BP-3S and BP-4S Igniter, (Product Family Nos. H43766, H43764, H43743, H43744) Unit No. 4190 under Service Tools/Remedial Systems or contact a Baker Hughes representative. The setting pressure is confined to the proper area of the setting tool through the use of O-ring seals. It is of critical importance that all O-rings be maintained in perfect condition and replaced after each use.

The E-4 wireline pressure setting assembly incorporates a piercing disk bleeder system to provide a safe, easy method of bleeding off trapped pressure before disassembling the W.L.P.S.A. after it has been run.
