Water pump pliers are fastening tools, mainly used for heater repair, faucet repair, car repair, water pipe repair, and agricultural machinery repair.
There are two types of water pump pliers of the CROWNMAN hand tool brand: one is chrome-plated pliers, size 10 inches and 12 inches; the other is black and polished pliers, size 10 inches.
There are good and bad water pump pliers on the market. Next, I can teach you a few ways to distinguish them.
Good quality: when adjusting the opening, the sliding is flexible and smooth without jamming; when the head is closed, the upper and lower teeth are aligned and the swing is small; when the water pipe and nut are twisted, there will be no slipping. The water pump pliers of the same specification are of better quality and heavier in weight, and the surface treatment is also very good.
Poor quality: When the opening is adjusted, the sliding will jam; when the head is closed, the upper and lower teeth are not aligned and the swing is large; when the water pipe and nut are screwed, there will be slipping. The water pump pliers of the same specification are of poor quality, lightweight, and have a poor surface treatment.
