These KF-25 Bellows Flex Coupling vacuum fittings follow ISO-KF standards and have a flange size of NW-25. They are commonly used to build foreline vacuum plumbing and process systems. They are often called quick flange fittings because they are quick to assemble. A circumferential clamp and centering ring form the vacuum seal between the connecting flanges (please see top right figure – click to enlarge). The centering ring contains a rubber elastomer o-ring. The standard sizes for quick flange fittings are KF-10, KF-16, KF-25, KF-40, and KF-50 with flange sizes NW-10, NW-16, NW-25, NW-40, and NW-50, respectively. They are made of corrosive resistant stainless steel.
Vacuum bellows is used to pump negative pressure and can only pass gas. Pipes smaller than 300mm are generally purchased at T = 0.15mm. They are compressible flexible pipes. There are both compressible and incompressible pipes. There are specifications such as 0.15mm, 0.2mm, 0.28mm, etc in thickness.
Our company’s hydraulically-formed bellows are relatively soft, with quality assurance, the introduction of advanced welding technology, smooth welding seams, various flanges can be welded according to requirements. Non-standard bellows can be customized according to drawings. All bellows can be customized in length and can be processed up to 4000mm. All manufactured products have passed the full inspection of the helium mass spectrometer leak tester and passed the test.
