I burned through 3 plastic wrenches trying to remove my Big Blue water filter housing. It seems I barely tightened it 18 months ago when I replace the filter element and o-ring (lubed with food grade silicone). This beast was not coming apart with those cheap, thin plastic wrenches. Two wrenches gave up their teeth, even with them doubled up - turning two wrenches together at the same time. The first wrench just twisted and snapped! This strap wrench got the job done in about 10 seconds - used a ratchet with a 16 inch cheater bar and old Big Blue finally surrendered. The alternative was to call the pump company and choke down a $100 service call, making this an awesome buy. I don't think this would actually have room to fit on any of my machinery oil filters, but using it just for the filter housing one time paid for itself. Very well built!
