These Neilsen CT1163 water pump pliers measure 16 inches (400mm), offering great leverage and a firm grip for various plumbing tasks.

To use these water pump pliers, simply open the jaws by squeezing the handles and place them around the object you want to grip. Then, adjust the position and tighten the pliers to hold the object firmly. When using, make sure the object is properly positioned between the jaws to avoid slippage. After use, wipe the pliers clean with a dry cloth to prevent rust. Store them in a dry place. Periodically, you can apply a little lubricant to the moving parts to keep them working smoothly.
