These Nor Cal CLAMP, CHAIN STYLE (NO RADIUS TYPE)  have part number NW-16-CC-TN, are new, and come with full Nor Cal warranty. Nor-Cal Products stocks a complete line of chain clamps and aluminum metal seals for converting elastomer seal NW (KF) and ISO flanges to UHV metal seals. They provide a number of benefits over elastomer seals: reduced outgassing, no permeation, no hydrocarbons, resistance to radiation and short half-life. Aluminum seals are used in high-energy physics, other UHV applications and, in some circumstances, cryogenic applications. Aluminum seals locate on the centering ring groove (inner centering) or outside edge of the flange (outer centering) depending on the size. (Inner and outer centering versions are available for all NW flange sizes.) Aluminum knife-edges are compressed by the sealing surfaces of the mating flanges when the chain clamp or ISO claw clamp is tightened. The resultant seal has a helium leak rate of less than 1x10-11 standard cc/sec. and can be baked repeatedly to 150°C.
