Adapter Ring

Spectrum Drilling Tools International manufactures a diverse range of Rotary Adapter Rings and Reducer Bushings designed to fit 75½”, 60½”, 49½”, and 37½” Rotary Tables. These adapter rings can come in either solid or split designs, and their configurations can vary from matching the same maker of the rotary table (e.g., LTI-LTI) or adapting from one brand to another brand (e.g., OILWELL-NATIONAL).

We offer adapter rings equivalent to those from NOV, suitable for Varco rotary tables, as well as Wirth Adapter Rings designed for MHWirth Rotary tables. Additionally, we provide Oilwell equivalent adapter rings tailored for Oilwell Rotary Tables. Customized Adapter Rings can also be manufactured upon request to meet specific requirements.
