Application

ISO-KF fttings can be used in a wide variety of aplications 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.

Installation

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).
