Special Features

  • Precise Rigid Bellow Assemblies: Features fixed-length, non-flexible stainless steel bellows permanently welded to ISO-KF flanges, providing robust, leak-tight connections for demanding vacuum applications (not designed for flexing or movement).
  • High Vacuum Performance: Engineered for high vacuum systems (typically 10<sup>-3</sup> mbar to 10<sup>-9</sup> mbar and beyond), constructed from high-quality 304 stainless steel for excellent outgassing properties and corrosion resistance.
  • Stable & Durable Connection: Offers exceptional rigidity and dimensional stability compared to flexible bellows, ensuring precise alignment and minimizing vibration transmission between connected components in critical setups.
  • Standard ISO-KF Flanges: Integrates common ISO-KF flanges KF40 with centering rings and clamps (clamps typically not included), ensuring compatibility and easy integration into existing semiconductor, laboratory, and industrial vacuum lines.
  • Ideal for Sensitive Environments: Perfect for semiconductor processing equipment, analytical instrumentation (mass specs, leak detectors), UHV research chambers, and any application requiring a stable, contamination-free, ultra-high vacuum connection without movement compensation.

Description

These KF40 series metal hose bellows flexible joints vacuum joints conform to ISO-KF standards, and the flange size is NW series
They are sheathless and butt welded. Usually used to construct pre-vacuum pipelines and process systems.
They are often called quick flange joints because they can be assembled quickly. The ring clamp and the centering ring form a vacuum seal between the connecting flanges.
Features:
1. Soft, flexible, easy to bend, vibration-absorbing
2. Has passed the helium leak test
specification:
Model: KF40
Material: 304 stainless steel
Application: Vacuum equipment
