KF Flange Vacuum Bellows Stainless Steel Flexible Hose
| KF flange vacuum bellows flexible hoses are widely used in high-vacuum pipeline systems where flexible, leak-tight connections are required. Each hose is built from thin-wall stainless steel with either spiral or annular corrugations, providing excellent flexibility and vibration absorption. They serve as a crucial link between vacuum components—allowing easy installation, disassembly, and system adjustment without tools or bolts. YDCT supply a full range of stainless-steel vacuum bellows in KF, ISO, and CF standards. The KF flange hose is designed to absorb positional offsets, reduce vibration transmission, and handle both static and dynamic movement under vacuum or clean-gas conditions. | |||||||||
Our regular KF flexible hoses cover KF10–KF50 sizes, available in standard lengths ranging from 100 mm to 2000 mm. Each hose comes with:
KF Flanges (304/316L stainless steel) welded on both ends.
Leak rate ≤ 5×10⁻⁹ Pa·m³/s, helium tested.
Bending life over 10,000 cycles, depending on installation conditions.
Operating temperature: −196°C to +450°C.
We try to keep standard items in stock for quick delivery, but large-volume or specific-length orders usually require a short production lead time.
Since the bellows are thin-walled, over-bending or torsion can reduce lifespan—something to keep in mind during installation.
As one of the experienced manufacturers of metal bellows, we’ve spent years working on how to make vacuum bellows more reliable and easier to fit into different systems.
We pay attention to the practical things, how the material behaves under stress, how the weld holds up over time, and how the sealing performs when the system runs continuously.
