4 pcs/set with different hook shapes and blunt head. With this o-ring remover tool you can easily reach and „grab” o-rings from the groove. The blunt head of the hooks assures that there will be no damage to the surface of grooves.  In the same time if the o-ring has to be repositioned in the groove, this tool is also the perfect choice since it will not damage the o-ring itself.
