NSF-certified thermally stable thinner


RINGFREE is a highly effective and thermally stable thinner and surface-active agent used to remove bentonite clays from the drill string. RINGFREE is used primarily to prevent bit balling and mud rings, but also is effective in reducing the viscosity and gel strengths of freshwater drilling fluids.

RINGFREE is certified to the stringent NSF/ANSI Standard 60 environmental specifications and contains no heavy metals. Since it dissolves rapidly, adding RINGFREE immediately impacts the rheology of aqueous-based drilling fluids.


  • Excellent clay dispersant that quickly penetrates sticky clays that can cause tools to become stuck
  • Works quickly to alleviate hole problems and reduce costly pulling problems or lost pipe
