The Hilka 300mm Box Joint Water Pump Pliers are heavy-duty, professional-standard tools designed for high-torque applications. Offering a larger frame than the 250mm model, these 12-inch pliers provide increased leverage and a wider jaw capacity, making them the preferred choice for heavy-duty plumbing, such as working on central heating pumps and large diameter pipes.

• Superior Leverage - The extended 300mm (12") length allows for greater force to be applied with less effort, ideal for seizing stubborn or rusted fittings.
• Heavy-Duty Box Joint - The 7 to 9-position box joint construction guides the moving handle through the other, preventing jaw-twisting and providing "extra strength" during high-load tasks.
• Precision Adjustment - Multiple position settings allow for fine-tuned jaw openings to accommodate flat, round, hex, and square work pieces.
• Enhanced Grip - Features double-dipped vinyl "soft grip" handles that offer a secure, non-slip hold and improved user comfort during prolonged use.
• Professional Durability - Crafted from high-quality Chrome Vanadium steel with a black phosphate finish for long-term corrosion resistance.
