Water Pump Pliers 1 products

Water pump pliers use a multi-groove slip joint to set the jaw opening, and their serrated jaws bite round pipe, nuts and irregular shapes over a far wider range than ordinary combination pliers; common sizes are 7"–12". They are among the most used pliers in plumbing, HVAC and automotive work. Check that the grooves are numerous and do not slip under load, that the jaw teeth are hardened, and that the handles cannot pinch your palm — cheap models pinch constantly.
