The Bosch water pump pliers are the robust choice for DIY plumbing and clamping. These versatile pliers have 26 teeth for gripping multiple sizes. By pressing a push button, they can be finely adjusted to a maximum jaw expansion of 46 mm. Operation, even in tight spots, is stable and comfortable thanks to ergonomic slim handles with soft grips. These pliers are built to be tough and long lasting with a strong, hard carbon steel composition and a black phosphate finish for high rust resistance.
