ISO-K / ISO-F Seals, Clamps & Bolt Kits
Single- and double-claw clamps make joining ISO-K flanges quick and easy. Nut and bolt kits are often the preferred option for other applications, including ISO-F flanges.
Whatever the case, elastomer O-rings in various compounds such as FKM, FFKM, Silicon, and Buna mounted over centering rings ensure the resultant seal is vacuum-tight and process chemistry compatible.

ISO Flange Assembly Instructions
Optional fastener flanges are joined around the periphery with clamps. Single-claw clamps join an OF flange to a tapped nonrotatable on a pump or gate valve. Double-claw clamps are used when a pair of OF flanges need to be joined. This fastening method allows the flange to be rotated for ease of component alignment.ISO-K / ISO-F Seals, Clamps & Bolt Kits Features
- Aluminum as well as 304 and 316 stainless steel centering rings
- Metric and Imperial threaded fasteners
- Over pressure and retainer spacer rings optional
