Tapered Rubber Bop Spool Casing Spool Adapter For Petroleum Drilling

Product Overview

The Tapered Rubber BOP Spool Casing Spool Adapter is engineered for secure and flexible connection between the blowout preventer (BOP) and the casing spool in petroleum drilling operations. Its tapered rubber sealing structure provides excellent pressure containment and vibration absorption, ensuring reliable performance under high-pressure and high-temperature conditions. Manufactured from high-strength forged steel with a durable anti-corrosion coating, this adapter meets API 6A standards and is widely used in wellhead assemblies, drilling risers, and BOP stacks, enhancing overall safety and sealing efficiency in demanding oilfield environments.
