North Central Illinois | Well, to tell the truth I'm not sure but I think mine has the relief valve. It has a button on top that looks like it would probably let off pressure. My biggest complaint with any new grease gun is the tips are so darn tight that it is really hard to get the tip off the zerk. Perhaps this relief valve will help a little with this but it always seems after some where and tear the tip will come off much easier than when they were new. | |
