SS304 KF Over Pressure Ring

Material

Material: SS304

Applications

KF flanges are a sexless design made from 304 stainless, they can be used in a wide range of applications including:

* Roughing and foreline plumbing

* Small pipe systems

* Systems need frequent cleaning or modification

* Research and teaching laboratories

Vacuum Range

Elastomer Seal:>=1 x10⁻⁸ Torr

Vacuum Range

Elastomer Seal:>=1 x10⁻⁸ Torr

Temperature Range

Viton: -50℃ to 200℃

NBR: -20℃ to 80℃

Installation

The lSO-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)
