John N.Costner, Bethlehem Steel Co.
There are, at present time, eight sucker rod manufacturers in the United States. They all manufacture sucker rods and coupling according to the specifications set forth by the American Petroleum Institute. In view of this, any discussion of the care and handling for sucker rods and couplings would quite naturally apply to any and all makes of sucker rods and couplings, regardless of the manufacture.
