KF Machined Clamp High Tension With Lock

Application

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.

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).

Material and Size

• Flanges, Blanks, Fittings: Stainless Steel 304 or 316L
• Clamps:
Aluminum or Stainless Steel 304
• Oring:
Viton

Description

The ISO-KF system is a modular, building block method of creating 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 maybe 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.
