Product Line
Key Products
OSC Model 60 Roller Reamers
Cost-effective rotary reamer with a non-sealed bearing design. Available in hole sizes from 5.7/8 inches to 35.7/8 inches with two cutter designs.
OSC Drilling Jars, HydraQuaker
The HydraQuaker hydraulic drilling jar delivers reliable double-acting impacts to free stuck drill string components in demanding drilling conditions.
OSC HydraQuaker Hydraulic Accelerator
The HydraQuaker Accelerator is designed to work with the HydraQuaker drilling jar to enhance jarring impact in shallow, deviated, and extended reach wells. By storing and releasing energy during the jar cycle, it improves performance, increases impact force, and helps protect the drill string from shock waves released as part of jarring.
OSC Borrox Roller Reamers
Borrox AP (Advanced Performance) is a high-performance sealed-bearing reamer designed to maintain hole gauge and improve borehole quality in a wide range of drilling conditions. Its customizable cutter options help reduce downhole torque, enhance durability, and adapt easily to different wellbore applications.
Sealed Bearing Reamers, Borrox AP®
The Borrox AP sealed-bearing reamer provides durable hole gauge control and torque reduction, with interchangeable cutter options optimized for soft to hard and abrasive formations.
Open Bearing Reamers, Model 60
The Model 60 open-bearing reamer supports effective hole gauge maintenance and torque reduction, using configurable cutter assemblies for a wide range of formation conditions.
Ring Type Joint Gaskets (RTJ)
RTJ gaskets are metallic rings for high-pressure, high-temperature flanges, used in oil, petrochemical, valves, and pipelines, compliant with ASME B16.20 and API 6A.
Spiral Wound Gaskets (SWG/SPW)
Spiral Wound Gaskets seal up to 250 bar and -200°C to 1000°C. Easy to install and remove without flange damage, with materials adaptable to varied conditions.
