Sinker Bars

Apergy's UPCO sinker bars provide concentrated weight above the pump to keep the rod string straight and in tension, which reduces buckling of the sucker rods and the pump plunger.

Our sinker bars are made from cold-rolled bar stock. The bars are surface turned and include API double sucker rod pins, shoulders, and wrench flats on both ends. One end has a reduced section for elevator seating and lifting.

We offer two material types that comply with API Specification 11B regarding sinker bar metal grades:

  • AISI 10XX Plain Carbon Steel complies with API Grade 1 – Carbon steel and has a minimum tensile strength of 90,000 psi.
  • AISI 46XX Nickel-Molybdenum Alloy Steel complies with API Grade 2 – Alloy and has a tensile strength of 90,000 psi.

Contact Apergy to learn more about our sinker bars and to find out which one is the best for your application.
