Fabian is right.... I was a little confused, then I did a search on Loctite. At least 9 different products with different characteristics appeared. Some are high temperature tolerant. Some are for cylinder fittings. Purple and green are for low-strength needs. Red is for permanent fasteners. I have a bottle of 246, but it does not list. So don't get hung up on one number. Read the Loctite site and get smart about their products, then choose between green, purple, and blue. Personally, I am staying away from red Loctite.
