Non-Rotating Float Collar (Single/Double Valve)

The COS Non-Rotating Float Collar is designed to prevent slurry backflow while ensuring smooth and efficient cementing operations. Installed near the end of the casing string, it incorporates an anti-rotation mechanism that prevents spinning during drill-out, improving both tool stability and performance. The valve system is built from high-strength rubber and polymer materials, delivering durability, sealing reliability, and resistance to downhole pressures.
