- 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 API grade K (AISI 46XXM) series steel. See table below for sizes and applications:
