ISO-K / ISO-F Seals, Clamps & Bolt Kits

Single and double claw clamps make joining ISO-K flanges quick and easy. 
For other applications including ISO-F flanges, nut and bolt kits may be the preferred options. 

Whatever the case, 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.
