Why You Need a Retainer Nut Wrench

Not sure you need a retainer nut wrench? When it’s time to replace a gauge protector (CD106) rubber cup (CD200), you first have to remove the retainer nut (CN101), which seals the rubber cup into the protector’s housing. Overtime the rubber cup wears and needs to be replaced. If you’re not careful, you can strip the retainer nut trying to remove it and will have to replace it, too. No spare retainer nut on hand? Then, you're waiting for another one to come in  In the oilfield, waiting  for something usually wastes money.

Many technicians try to use pliers or two screw drivers inserted into the slots to unscrew and remove the retainer nut. But, when these methods don't work, they just smash the retainer nut to break it and remove it. No use breaking a perfectly reusable part or having to wait; use the CW109, and the retainer nut will be a snap to remove. Made of sturdy material right in our machine shop, Crown's retainer nut wrench will be an excellent addition to your tool box on hand when it's time to replace the next gauge protector rubber cup. After all, having the right tool for the job saves time, money, and effort.
