Del-SealTM CF Flanges
Del-SealTM (Conflat® compatible) metal seal flanges have become America’s industry standard and the world’s leading choice for ultra high vacuum flanges. They are listed with both the American standard size designations as well as the European DN CF standard. They are offered in 13 sizes from 1.33'' (DN16 CF) to 16.5'' (non-DN standard) diameters. Copper gaskets, Viton® elastomer gaskets and bolt kits are also detailed.

ISO NW Kwik-Flange
Kwik-FlangeTM (ISO NW compatible) elastomer seal flanges were specifically designed for high vacuum system connections requiring quick and frequent assembly and disassembly. They have been modeled after the globally established ISO NW flange format. ISI offers the Kwik-FlangeTM system, including mounting accessories, in tube sizes from .750'' (DN16 KF) to 2.00'' (DN50 KF).

Baseplates
Baseplate elastomer seal mounts are self-contained mounts, originally developed for the vacuum coating industry and designed for use with bell-jar systems or flat Baseplate vacuum chambers. These blank mounts fit through 1.00'' holes. As an added convenience, ISI blank Baseplate mounts are fitted with a female 3/8-16 thread to support custom vacuum structures.

Blank NPT Fittings
National Pipe Thread (NPT) mounts are also offered as a line of standard blank mounts. These are made of 316 stainless steel material and used to blank-off unused NPT vacuum ports. These mounts are typically sealed using conventional plumber’s Teflon® tape and are suitable for rough vacuum applications.

INTENDED OPERATING CONDITIONS
Electrical ratings are determined by various factors, including dielectric strength, geometry and system operating pressure. Please note that all ISI catalog products are electrically rated for operation with one side in dry atmospheric conditions and the other side in a vacuum environment with a maximum system
pressure of 1 x 10-4 Torr. We advise that users make allowances for deviations from stated operating parameters and take adequate safety precautions when feedthroughs are operated at high voltages or high currents.
