This 1 blind flange is 316 Stainless Steel with a raised face face in 150#. If youÕve ever needed to bolt pipe to a valve or piece of machinery, this blind flange is the part that makes that connection possible. Blind flanges are used to close off the end of a line, valve, or vessel nozzleÑgreat for isolating sections for service. This is the clean way to cap a connection without changing the rest of your piping layout. ItÕs a favorite in more demanding environments where long-term resistance is the priority. ItÕs built with a raised-face surface to help create a confident seal when paired with the right gasket. PLYET Industrial Supply focuses on practical, jobsite-ready components that help you keep systems moving.
