ISO-KF (NW) Seals, Clamps & Bolt Kits

Wing nut and lever clamps make joining ISO-KF (NW) flanges quick and easy. 

For other applications, bulk-head clamps and finger clamps are preferred. Elastomer O-rings in a variety of compounds such as FKM, FFKM, Silicon, and Buna mounted over centering rings ensure the resultant seal is vacuum-tight and process chemistry compatible.
