Collet Plier Knipex 85 51 250 AF Grey Red

The Knipex 85 51 250 AF collet plier opens, holds and moves all types and sizes of spring hose clamps up to 70 mm diameter. Its slim design and rotating jaw inserts allow access in confined or unfavourable positions, making it possible to work on large charge-air hose clamps as well as delicate clamps in engine compartments. The pliers have long handles and an adjustable joint for a wide jaw opening, providing safe, controlled operation with minimal effort.

Advantages

Rotating universal jaw inserts permit operation from different angles and make it possible to reach clamps that are not installation-friendly. The adjustable pliers joint enables a jaw opening up to 80 mm and a clamping range over 40 mm, giving ample room for manoeuvre across clamp sizes. Long handles increase leverage so large spring hose clamps can be opened with little manual force, and an integrated one-hand release locking device holds the closed clamp without continuous effort.

Suitable for

• Opening and holding spring hose clamps up to 70 mm diameter
• Work on charge-air hoses, coolant lines and engine compartment clamps
• Repair and maintenance tasks where clamps are positioned at awkward angles

How to use

Place the rotating jaw inserts around the spring hose clamp and adjust the pliers joint to obtain the required jaw opening.

To release the clamp, open the locking device with one hand and allow the jaws to return to their resting position. Rotate the jaw inserts as needed to approach the clamp from a favourable angle.

Usage recommendations

Use the Knipex 85 51 250 AF for clamps up to the stated diameter and avoid applying excessive force beyond normal manual operation. Regularly check the rotating jaw inserts and the locking mechanism for wear to ensure safe, reliable performance.
