KF Flanged Formed Bellows for HV Systems
At TFM, we specialize in manufacturing KF flanged formed bellows specifically designed for high vacuum (HV) systems. These bellows are crafted from 300 series stainless steel flexible hoses and feature 304L stainless steel KF (QF) flanges. The KF (QF) flange is commonly used in through-line or foreline vacuum plumbing, as well as for basic HV chamber ports, ensuring dependable sealing and connectivity.
MH-Series Bellows
- Material: Constructed from thin 300 series stainless steel, these bellows are engineered to withstand repeated flexing cycles without compromising performance.
Key Features of Our Flexible Hoses:
- Unbraided Flexible Hoses: These hoses can extend up to 10% beyond their original length and compress up to 15%, providing flexibility for dynamic environments.
- Braided Flexible Hoses: The braided sheath offers additional protection, shielding the convoluted hose from potential damage, enhancing durability in demanding conditions.
- Short Flexible Hoses: Ideal for correcting minor component misalignments, ensuring smooth integration within systems.
- Longer Flexible Hoses: Commonly used as roughing lines, these are well-suited for more extensive vacuum applications that require flexibility over longer distances.
TFM supplies these durable KF flanged bellows, tailored to meet the specific needs of HV systems, ensuring reliability and flexibility in high-vacuum environments.
