KF Flexible Bellows (Hose) Vacuum Bellows Connection, KF25 (NW 25), Stainless Steel Bellow
We fabricate these KF flanged hydraulically formed bellows for HV systems from 300 series stainless steel hoses and 304L stainless steel KF (QF) flanges.
These KF Metal Hose Bellows Flex Coupling vacuum fittings follow ISO-KF standards and have a flange size of NW-25. They are unsheathed and butt welded. 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.
The main Vacuum products are KF, ISO and CF series elbow, tee, reducer, cross, vacuum bellows is suitable for various vacuum or vacuum system, at the same time can be custom-made non-standard parts, widely used in semiconductor, medical, solar photovoltaic, and other fields
Vacuum Bellows Feature :
Fabricated from thin 300 Series stainless steel
Flexible Bellows Connections Size: NW 10, NW 16, NW 25, NW 40, and NW 50.
Withstand many flexing cycles
Unbraided Hoses: Extend up to 10% beyond their live length and compress up to 15%
Braided Hoses: Braided sheath helps protect convoluted hose from damage
Short Hoses: Often used to correct minor component misalignments
Longer Hoses: Work as roughing lines
Short hoses are often used to correct minor component misalignments while longer hoses are ideal for use as roughing lines.
Thin wall hose and bellow assemblies are fabricated from Series 300 stainless steel
Hoses can be made compatible with KF or ISO "K" terminations
