Collet Plier Knipex 85 51 250 C Black Red

The Knipex 85 51 250 C collet plier is a purpose-built tool for handling standard click clamps with and without a limit stop in the locking mechanism. Its asymmetrical, 360° rotatable gripping jaws and slim overall design enable access in confined spaces such as modern engine compartments. The softly serrated jaw surface allows safe detachment of hoses that have become stuck without crushing fittings.

Advantages

One plier covers both types of click clamps thanks to rotating, asymmetrical jaws that adapt to clamps with or without a limit stop. The slim profile and 360° rotation provide optimal accessibility in tight engine bays. Soft serrations on the jaws permit powerful yet gentle removal of hoses adhered by deposits or heat exposure. Knipex production quality—precision machining, multi-stage heat treatment and durable materials—ensures long service life for professional daily use.

• Removing and holding click clamps on engine hoses

How to use

Position the rotatable jaws around the click clamp and rotate the gripping head to achieve the best angle for access. Squeeze the handles to open or hold the clamp, applying steady force so the softly serrated jaws grip the clamp securely. When removing hoses that are stuck, use controlled force while maintaining a stable grip to avoid crushing the fitting. Release the handles slowly after repositioning or removing the clamp.

Usage recommendations

For safe and long-lasting tool performance, select the correct jaw rotation before applying force, avoid using the pliers as a hammer or prying tool, and keep the jaws clean of oil and heavy deposits. Use eye protection when working near pressurized or loaded hose systems.
