ISO-K Single Claw Clamp for ISO-K 320, 400, and 500, fits ISO-320K thru ISO-500K Vacuum Flanges, 50mm long M12-1.75 Bolt, 304 Stainless Steel

These single claw clamps, made of 304 Stainless Steel, are used to join a size NW 320 thru 500 ISO-K vacuum flange to an M12-1.75 mm tapped flange. These single clamps fit ISO-K DN 320 thru 500 vacuum flanges and follow vacuum technology standards described in DIN 28404 and ISO 1609. The ISO-K style fittings are quick to assemble using claw clamps (please see figure - click to enlarge) and can be connected in any orientation. The claw clamp hooks into a ridged groove in the back side of the ISO-K vacuum flange. The union requires a centering ring which contains rubber, elastomeric, O-ring to form the vacuum seal between the two flange faces. The clamps are commonly used to build process vacuum plumbing and systems for industrial vacuum applications. The ISO standard sizes for large LF flanges are ISO-LF DN 63, 80, 100, 160, 200, 250, 320, 400, 500, 630, 800, and 1000. These single claw clamps are made of 304 Stainless Steel and work with flange sizes ISO-LF 320, 400, and 500. The quantity of clamps required per flange size is given below.
