Part # 700656-0000, Centering Washer

Also called adapter buttons, these special washers are used when joining glass pipe to ANSI-flanged pipe. The bolt holes in ANSI flanges are larger than the holes in the flanges for the glassware. Instead of using standard washers, which would allow the bolts to wobble loosely in the flanges, by using centering washers, the bolts are automatically centered in the bolt holes. Washers are made of plated carbon steel.
