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 components are assembled by inserting a centering ring between the two flange faces, then securing the assembly with a flange encompassing clamp
