Product: Stainless Steel Vacuum KF Centering Ring with Outer Ring and O'ring
Features:
Viton O'ring bakeable to 200°C intermittently, sustained use to 150°C.

opposing pairs of clamps or bolts until the first metal-to-metal contact is made between the inner surfaces of the
flanges and the spacing lips of the centering ring.
