At Kriloha Ltd., we supply Mechanical Spring Jars, reliable wireline tools that generate controlled upward and downward impact forces using compressed spring mechanisms. Unlike hydraulic jars, spring jars provide instantaneous energy release, making them particularly effective for light-to-medium fishing and valve operations. Manufactured from forged alloy steels with precision-machined springs, Kriloha spring jars are designed for long service life under HPHT and sour well conditions. Applications include fishing operations, valve manipulation, and tool release jobs, where controlled but fast jarring is needed. Each unit undergoes impact calibration, cycle fatigue testing, and endurance trials, ensuring dependable field performance. As a supplier and facilitator, Kriloha Ltd. provides custom jar sizes, replacement spring kits, and technical operator training, making our spring jars the preferred choice for operators seeking dependable jarring tools without hydraulic complexity.
