ISO-KF fittings can be used in a wide variety of applications including:
• Roughing and foreline plumbing
• Small systems
• Systems requiring frequent cleaning or modification
• Research and teaching laboratories
ISO-KF components are primarily designed for use at subatmospheric pressure. Because of the large number of elastomer seals used.


The ISO-KF system is a modular, building block method ofcreating a piping system. There are several advantages in the use of ISO components. Since component dimensions are standardized, elbows,tees, crosses or valves for a given size may be interchanged. The flanges are ''sexless'' and the seal is symmetrical, so that the components are rotatable. By using ISO components, system assembly is quick and cost effective. See Figure 1 for the ISO dimensions of flange sizes 10, 16, 25, 40 and 50. These dimensions apply to ISO-KF flanges of these nominal diameters throughout this catalog.


The ISO-KF components are assembled by inserting a centering ring between the two flange faces, then securing the assembly with a flange encompassing clamp (see Figure 2).
