KF/NW/ISO Vacuum Pipe Ring Fittings SS304/SS316L/Aluminum Center Ring with O-Ring with FKM/NBR Seals 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
• 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.

Description

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.

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).
