Product Detail

An ISO Bolted Blank Flange is a type of vacuum flange used in high-vacuum applications. It is a circular plate with bolt holes that are used to close off an unused vacuum port or to create a vacuum-tight seal. The flange is bolted onto a matching ISO flange using bolts and nuts to create a tight seal.

ISO Bolted Blank Flanges are typically made of stainless steel and are available in various sizes and materials to fit a wide range of vacuum systems. They are commonly used in vacuum chambers and other vacuum applications where a secure and leak-free seal is necessary.
