Review on High-Quality Screw Caps for Replacement Gas Can: Perfect Fit for Gott, Rubbermaid, Briggs & Stratton, Kolpin, and Rotopax Fuel Containers by Sean Webb

This is rubbish. I bought these to replace the broken one on my old gas bottle. They were the right size and seemed to be size compatible. I put one on though and when I checked the glass the next week I beveled it, it was split and cracked like it was rotten. AFTER A WEEK! The same happened with the second. I don't think the manufacturer used the right type or plastic or anything. Not worth your time and money.
