Circlip pliers Knipex 44 31 J22, chromium-vanadium steel, plastic handles, 180 mm

Knipex 44 31 J22 circlip pliers are precision hand tools designed for installing and removing internal and external circlips with diameters from 8 to 140 mm. Forged from chromium-vanadium steel and oil-hardened for strength, these 180 mm pliers combine a compact form factor with non-slip solid tips and comfortable plastic handles, making them suitable for maintenance, assembly and repair tasks where reliable gripping and long service life are important.

Advantages

The pliers feature a forged, solid-style body and hardened tips that resist wear during repeated use. Non-slip, solid tips provide secure engagement with circlips to reduce the risk of deformation or loss during installation or removal. The chromium-vanadium steel construction with oil hardening improves toughness and durability, while the ergonomic plastic handles offer a comfortable grip and control in confined work areas. At 180 mm length and approximately 140 g weight, the tool is compact and easy to handle for precision tasks.

How to use

Select pliers that match the circlip type (internal or external) and diameter within the 8–140 mm range. Position the tips inside or outside the circlip so they engage securely, then squeeze the handles evenly to compress or expand the circlip as required. Maintain steady control while withdrawing or fitting the circlip to avoid slippage; use protective eyewear if working with tensioned circlips. After use, wipe the pliers clean and store them in a dry place to prevent corrosion.

Usage recommendations

For safe and long-lasting performance, use these pliers only on circlips within the specified diameter range and avoid prying or levering with the tool. Periodically check the tips for wear and maintain the steel surfaces with light oiling to preserve the hardened finish and prevent rust.
