ABSTRACT:
A thin walled (e.g., 1/16th inch), cylindrical, stainless steel inverted working barrel and seat adapted to concentrically insert into and sleeve upwardly within the lower end of a conventional oil or gas well production string and act as a replacement for or in lieu of a conventional thick walled working barrel. The production string structurally protects the thin walled barrel allowing for a significant savings in initial or replacement costs.
