ISO-K to KF Straight Adapter

Description

The ISO-K to KF Straight Adapter is designed to connect ISO-K flange sizes to ISO-KF reducer flange sizes in a straight configuration for vacuum systems that require two different connection standards in one assembly. The catalog states that other nominal diameters and dimensions are available on request. It is listed with a pressure range of 1 × 10⁻⁸ mbar to ambient pressure for elastomer seal and 1 × 10⁻⁹ mbar to ambient pressure for metal seal. It is available in Stainless Steel 304 / 1.4301 and Stainless Steel 316L / 1.4404.
