Wheeled Rod Guide Couplings have worked successfully in thousands of applications since 1982.Sucker rod guide/couplings for severely deviated & directional wells Used successfully for over 25 years by over 90% of major oil & gas companies in over 40 countries - onshore & off shore Wheels are field-replaceable Reduce wear & prolong the life of sucker rods & tubing.Wheel angles are designed to centralize rod string in tubing. Wheels' rolling action reduces friction, rod load, and wear.Wheels "span" tubing couplings.Wheel installation & design assures smooth rolling action & easy replacement.
