Product Description

Stainless Steel 316 ISO Vacuum Flange

ISO Flanges are another metric flange that is larger than the KF flanges  They are manufactured according to the DIN 28404/ISO 1609 standard The flange size is based on the largest nominal I.D. tube, in millimeters, that can be welded to it. For example, the through hole of an ISO 100 flange is 100mm, or about four inches. The standard sizes are ISO 63, ISO 100, ISO 160, ISO 200, ISO 250, ISO 320, ISO 400, ISO 500 and ISO 630. Less common is the ISO 80 size. There are two types ISO-K and ISO-F.
ISO-K flanges have a groove cut into the back of the flange so that a claw clamp can grab ahold of it. Because the letter "K" sounds the same as a "C" it can be helpful to remember that ISO-K requires a Claw Clamp.

ISO-F flanges have holes into the flange that can be used to bolt the two flanges together. These holes most commonly are through holes where a bolt is placed through both flanges; however, the holes can also be tapped where there is no access to place a nut (or nut ring) behind one of the flanges. It can be helpful to remember the ISO-F flange is flat and there is no groove for a claw clamp.

Applications
They can be used in the pressure range as low as 1×10-8Torr or mbar. The operating and bakeout temperature range depends upon the O-ring material. The most common O-ring material is FKM (Viton-A) which is suitable for the operating temperature range of 32 deg F to 356 deg F (0 to 180 deg C) and can be exposed to short-term temperatures in the range of -15 deg F to 400 deg F (-26 to 204 deg C). The leakage and permeability rate of these flanges with FKM is 1×10-9std cc/sec of Helium.
