Midland Black Ductile Iron Blind Flange

Midland ductile iron blind flanges provide a secure, pressure-rated method of sealing the end of Class 150 piping systems. Manufactured from durable ductile iron with a black protective finish, these blind flanges deliver excellent strength and long service life in commercial, industrial, and municipal piping applications.

Available in multiple nominal pipe sizes from 2 through 8 inches, each flange is drilled to ASME Class 150 bolt patterns for compatibility with standard raised face flange connections.
