happy days said:Problem I have found with pump pliers is after a while they snap closed while tightening things up, also alot of pump pliers have teeth for a better grip, not good when tightening chrome ie radiator valves, hence adjustables. For the first time and possibly only time, I disagree with Harvey, adjustables are very useful
I have one pair of these pump pliers and if you put any pressure on them at all, they just shut completely taking skin and flesh with them.
I think they may just be FUBAR. Buy cheap tools, and you get what you pay for.
