Figure 8 Blind Flange
- Product Description
-
Figure 8 Blind Flange – Open or closed, one piece does both
A figure 8 blind flange looks like its name: one solid disc and one ring joined by a short web. Bolt it between two flanges, spin it 180°, and the line is either wide open or positively blanked. No valve seats to leak, no gaskets to replace every month—just a single forging that stays in the piping system for life.
