Blind flanges (also termed “closure plate flanges”) serve as permanent or temporary termination points in piping systems. Unlike standard flanges, they feature a solid center without a borehole, creating an impenetrable seal when bolted to pipe ends, valves, or pressure vessels.

At JS FITTINGS, we manufacture industry-compliant blind flanges in all sizes and pressure classes, offering three sealing face variants:

Flat Face (FF)

Raised Face (RF)

Ring-Type Joint (RTJ)
