What type of material is typically used for flat ring gaskets?

Plastic
Metal
Paper
Rubber

The correct answer is: Rubber

Flat ring gaskets are commonly made from rubber due to its excellent sealing properties, flexibility, and ability to compress and conform to surface irregularities. Rubber gaskets create a tight seal that effectively prevents leaks in piping and other applications. They are ideal for high-pressure systems because rubber can withstand varying temperatures and pressures without losing its sealing capability. Moreover, rubber can be formulated to resist various fluids, making it versatile for different service conditions. Materials like metal, paper, and plastic can also be used for gaskets in certain situations, but rubber is the most prevalent choice for flat ring gaskets specifically because of its durability and performance in sealing applications.
