Peak Family linear jar

Friction-reducing performance for wireline operations in high‑angle wells

The linear jar of Peak Family™ flow control and well intervention tools is ideal for high‑angle wells where a normal link‑type spang jar or tubular jar may be limited. Its unique dual-roller system reduces friction between the jar rod and outer housing. The resulting smooth bidirectional strokes drive upward and downward forces to power most routine wireline functions in deviated wellbores.

• Wireline operations in high-angle, deviated wells
• Fishing operations in suspected wire, debris, or other foreign-matter environments
• Large-ID tubing or casing operations

• Improves durability with increased jar rod diameter
• Outperforms standard spang jars for fishing operations in wellbores with suspected wire, debris, or other foreign matter
• Supports routine wireline functions in large-diameter tubing or casing where conventional spang jars are prone to buckling or scissoring

• Unique dual-roller system
• Wide range of connection options to meet customer requirements
• Compatibility with the Peak Family power jar and WellGlide™ roller-centralizer sub
