SS304 SS316L Vacuum Half Nipple Weld Flange Stainless Steel Short/Long Weld Stub Flange Vacuum Fittings for Semiconductor

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

Material and Size

•  Flanges,Blanks,Fittings:Stainless Steel 304,316L or Aluminum
•  Clamps:Aluminum or Stainless Steel 304
• O-Ring:Viton/NBR/EPDM
• Size:KF10-KF50(See Figure 1

Vacuum range

Elastomer seal: >= 1 x 10-8 Torr

Temperature range

Viton: -50°C to 200°C

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).
