Flexbars and Lift Subs

• Built to precise specifications and designed to enhance the operation of our Effective Weight Sinkerbars.

• Flexbars provide a 1° off center deflection between each sinkerbar which allows the weight of the system to align itself longitudinally in the tubing string.

• The Lift Sub was developed to provide an alternative to Flexbars when deviation is not a problem. The Lift Subs are similar to the Flexbars but due to their 14" length, they are not as flexible.

• Flexbars and Lift Subs also function as an elevator neck when sinkerbars without necks are desired. In this instance, should damage occur to the sinkerbar string, the Flexbars or Lift Subs should absorb the damage and their replacement is both simple and economical.

• Flexbars and Lift Subs can be used in place of a pony rod and two couplings, and since the boxes and body are machined from a single piece of steel, a stronger more effective unit is produced, and fewer connections are required.

• Flexbars can accept any molded-on rod guide for use above the pump and in between Flexbar Sinkerbars or sucker rods.

• Flexbars and Lift Subs are manufactured from AISI 4623 (API grade K) steel. See table below for sizes and applications:
