After using a can of Great Stuff foam insulation once, I was surprised to find that Home Depot doesn't sell replacement nozzles. After a short use there was still a lot in the jar but it was unusable because the spout was clogged. But look for Revane and you will find it. These replacement nibs were affordable, fit perfectly in a Great Stuff tin, and performed just like the original nibs. The only difference (aside from the color, which seems unimportant) is that the original nozzle could be "closed" by twisting the tip and these replacements don't. I haven't used this feature, but I mention it because others might.
