Vacuum KF Flange (SUS304, Short-Weld)

Hello, this is VALVEPARK.

Today we would like to introduce the Vacuum KF Flange (SUS304, Short-Weld) - an essential component that no vacuum system can do without. Whether you are building or maintaining vacuum equipment, this is a part you have almost certainly encountered. Let us break down its features and advantages in a straightforward way.

What Is a Vacuum KF Flange?

The KF Flange is a vacuum connection component that follows the Klein Flange standard, designed for quick and convenient connection of vacuum piping and equipment. The product introduced today is manufactured in:

• SUS304 stainless steel material
• Short-Weld type structure

combining both durability and installation efficiency.

Product Features

SUS304 Stainless Steel Material

Excellent corrosion resistance with minimal risk of deformation or rust even after extended use. A critical factor for maintaining stable performance in vacuum environments.

Simple Clamp Connection Method

A KF flange connection consists of three elements: Flange + Centering ring (with O-ring) + Clamp. Assembly and disassembly are quick without complex tools, making maintenance and replacement far more convenient.

Short-Weld Structure

Designed with a shorter weld length, allowing easier installation even in confined spaces and providing greater flexibility in equipment layout design.

Characteristics of the Weld-Type Flange

Because the Short-Weld type is a weld-on flange, it offers the following advantages:

• Flange connection in tight spaces
• Body and flange integrated as one unit → minimized leak paths
• Excellent long-term hermetic sealing performance

Note: After installation, flange replacement requires re-welding. Therefore, it is mainly used on fixed piping lines.
