In vacuum technology, even the smallest component can make the biggest difference. From advanced research labs to industrial manufacturing facilities, maintaining vacuum integrity is critical—and that begins with the right flange and a trusted supplier. Whether you're building a new vacuum system or upgrading an existing one, the KF Vacuum Flange and a reliable Vacuum Chamber Manufacturer like VacuumChamber. com can elevate your performance and reliability to new heights.
What is a KF Vacuum Flange?
The KF Vacuum Flange (also known as NW or QF flange) is a standardized vacuum fitting used across a wide range of systems operating in the high-vacuum range (down to ~10⁻⁷ Torr). Known for its simplicity and effectiveness, the KF flange uses an O-ring sealed assembly with a centering ring and clamp to ensure a tight, reliable connection between vacuum components.
Why Engineers Choose KF Flanges:
Fast installation and removal – ideal for systems requiring frequent maintenance or reconfiguration
Leak-tight design with excellent sealing integrity
Interchangeability – compatible with global vacuum equipment standards (ISO-KF)
Made from corrosion-resistant stainless steel for durability and long-term reliability
KF flanges are commonly used in:
Laboratory and scientific instruments
Semiconductor equipment
Analytical and cryogenic systems
Portable and modular vacuum setups
Looking for premium-quality KF flanges with consistent tolerances? VacuumChamber.com offers a full range of KF sizes and configurations built to perform under pressure.
