Spectacle Blind Flange also known as a figure-8 blind – is generally a piece of metal that is cut to fit between two pipe flange and usually sandwiched between two gaskets. A spectacle blind is often made from two metal discs that are attached to each other by a small section of steel.
The shape is similar to a pair of glasses or “spectacles” – hence the name spectacle blind. One end of the blind will have an opening to allow flow through the pipe during operation and the other end is solid to block flow during maintenance. They are generally installed as a permanent device to separate process piping systems.
ATT's spectacle blinds are a single piece of machined metal designed to eliminate the hassle of having seperate paddle blind and spacer sets. When a section of your pipe needs to be isolated from the rest for maintenance, a spectacle blind or spec blind can make the process much easier
