Spectacle Blind - ANSI Class 900 (in) A ring spacer is bored to match the pipe I.D. and thickness of the spacer it replaces. A single spacer is has no bore and is designed to complete shut-off of a pipeline or valve. A spectical blind is a combination of both a ring and single spacer. To make switching from one to the other, especially in the larger sizes, a bolt hole or slot in the spacer bar is provided for rotation. Surface finish to be specified. These blind/spacers are designed for ASME B31.3 and ASME B16.5. Pressure temperature rating in accordance with ANSI/ASME B16.48 for sizes 1/2" to 24".
