Flexbar Polyethylene Sleeved Sinkerbars (Polybars) ... Reduce Tubing Failures

  • Flexbar, Inc. has combined the benefits of our effective weight sinkerbars and high-density polyethylene to further reduce tubing leaks, rod parts and pump repairs. This new patent-pending product concept is trade named Polybar.
  • Testing indicates that Flexbar Polybars can reduce tubing failures by 89% over sucker rod strings already utilizing bare or non-sleeved sinkerbars.
  • Bare sinkerbars have proven to reduce tubing failures by 69%. For problem wells where other tubing wear solutions have failed, Flexbar Polybars could be the answer.
