I was trying to find a product that I buy at a hardware store where I work. I saw them and thought they were close to this product. Not at all. Almost all are broken. Today I took out one of the tubes of sealant. The seal has a smaller opening and does not keep the product "wet" in the spout. After working and working on it and using it, I tried to plug it back in. Even though the hole is much bigger now, I couldn't insert the connector without it starting to break. I also tried pulling one a few weeks ago. It broke off in the pipe. I can't trust these to work. You might as well use tape or rope caulk to seal them like I did!
