Products

The cornerstone of our success is the ability to utilize the data collected from our diagnostic services to recommend the best products and their optimal design and application.

 Sucker Rods

Steel Sucker Rods:

Penta supplies Upco sucker rods, which are manufactured to API specs and are fully normalized and tempered as required by grade.

Fiberglass Sucker Rods:

Since 1976 FIBEROD personnel have pioneered and engineered the fiberglass sucker rod for the oil industry. All FIBEROD rods meet or exceed API specifications for reinforced plastic sucker rods.

FIBEROD is ideally suited for increasing production in high fluid level wells, overloaded equipment or corrosive environments.

 Sinkerbars

Sinkerbars are designed to operate within the comprehensive loads which occur above the pump. By installing Sinkerbars above the pump, tension is maintained in the rod string.

Sinkerbars can significantly reduce rod and tubing wear failures, and extend the operating life of any composite steel, or fiberglass sucker rod string.
