Knuckle Jars In Detail

At Kriloha Ltd., we supply Knuckle Jars, versatile fishing tools that combine jarring capability with flexible articulation. Unlike standard jars, knuckle jars can bend, allowing tool strings to navigate deviated or horizontal wells while still delivering effective upward and downward impacts. Constructed from forged alloy steels with precision knuckle joints, Kriloha knuckle jars are API/ISO compliant and suitable for HPHT environments. Applications include fishing stuck tools, freeing lodged equipment, shifting downhole sleeves, and delivering controlled impact force in deviated wellbores. Each jar undergoes impact calibration, cycle life testing, and knuckle articulation checks, ensuring reliability. As a supplier and facilitator, Kriloha Ltd. provides custom knuckle sizes, spare kits, and operator guidance, making our knuckle jars the preferred solution for fishing in complex well geometries.
