If you have ever used the RTV High Temp Gasket Maker you are aware the original lids fall apart before all of the tube can be used. Instead of throwing the tube away you can use these flexible and durable push on caps. Vinyl material creates a tight seal as well as being flexible, durable, and reusable. The gasket material can easily be wiped off as it does not stick to it. These caps are designed to be used for the 3oz./85g tubes. Color is Black. Sold in pairs. All of my products are made and shipped from the USA. I offer free shipping to the United States.
