Hydraulically (Hydro) Formed Bellows - KF(QF) Flanged Thin Unbraided Wall

We fabricate these KF flanged hydro formed bellows for HV systems from 300 series stainless steel flexible hoses and 304L stainless steel KF (QF) flanges. The KF (QF) flange is used for through- or foreline vacuum plumbing and for simple HV chamber ports.

Hydraulically (Hydro) Formed Bellows Feature:

  • MH-Series Bellows:
    • Fabricated from thin 300 Series stainless steel
    • Withstand many flexing cycles
  • Unbraided Flexible Hoses: Extend up to 10% beyond their live length and compress up to 15%
  • Braided Flexible Hoses: Braided sheath helps protect convoluted hose from damage
  • Short Flexible Hoses: Often used to correct minor component misalignments
  • Longer Flexible Hoses: Work as roughing lines
