ISO-LF Socket Weld Flange DN200ISO-LF, OD 8, 304SS

The ISO flange (also called Large ISO) is used for HV chamber ports and uses clamp fasteners. Each flange face is counter-bored or grooved to receive a metal centering ring with an elastomeric o-ring around its O.D. As with KF, the ISO centering ring both aligns the flanges and holds the o-ring in place. ISO flanges are limited (by the o-ring's properties) to applications with temperatures between ~0° C and 120–180° C, and pressure from atmosphere to ~10-8 torr or mbar.
