EAJ3LC, Aquajack Subsea Bolt Tensioner, 1 1/4" - 1 3/8" Maximum Thread Range

Enerpac EAJ3LC is a robust subsea bolt tensioner from the Aquajack series, optimized for precise tensioning of 1 1/4"–1 3/8" bolts in challenging underwater environments such as offshore oil & gas, pipelines, and marine maintenance. Featuring a long piston stroke for efficient operation, misalignment compensation for reliable alignment, and no-spill overstroke prevention for enhanced safety, this tool integrates quick hose connections and visible stroke indication, enabling rapid deployment with minimal downtime while supporting high-pressure hydraulic pumps for consistent performance up to 1500 bar.
