ISO-K to ISO-F Adapter Flange

Description

The ISO-K to ISO-F Adapter Flange is designed to connect ISO-K flange sizes to ISO-F reduced nominal diameters in vacuum systems where two different flange standards must be joined reliably. The catalog lists this product with a pressure range of 1 × 10⁻⁸ mbar to 500 mbar over pressure for elastomer seal and 1 × 10⁻⁹ mbar to 500 mbar over pressure for metal seal. It is available in Stainless Steel 304 / 1.4301 and Stainless Steel 316L / 1.4404.
