Piston Ring Pliers, 80-120mm Capacity, Self-Adjusting Spring Tension
Brief Overview
This self-adjusting piston ring pliers tool is engineered for fast, controlled installation and removal of piston rings in the 80-120mm diameter range. The design features a proven spring-tension mechanism that automatically adapts to ring diameter variations, eliminating repetitive manual adjustments during engine assembly work. For mechanics working with larger ring applications, piston ring pliers with extended 110-160mm capacity are also available. When combined with complementary tools like a piston ring compressor for initial ring compression, this pliers becomes part of a complete piston ring service toolkit.

Why This Tool Matters
Engine assembly demands precision and speed. Manual piston ring handling without proper tooling risks ring damage and wasted labor time. This self-adjusting pliers eliminates guesswork—the spring mechanism compensates for ring diameter variations automatically, allowing mechanics to focus on proper ring seating rather than tool adjustment. For shops handling diverse engine sizes, this 80-120mm range covers a significant portion of small-to-mid displacement engines, making it a core inventory item.
