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 assure the resultant seal is vacuum tight and process chemistry compatible.
