KF (QF) Adaptive Centering Rings
Activair.cz > Products > Vacuum componets > KF (NW) Flanges & Components > O-Rings & Centering Rings > KF (QF) Adaptive Centering Rings
These centering rings are used for mating different size KF flanges and include both the centering ring and o-ring. The KF (QF) flange is used for through- or foreline vacuum plumbing and for simple HV chamber ports.
KF Adaptive Centering Rings Feature:
- Rings available in stainless steel or aluminum
- Stainless steel centering rings come with fluorocarbon o-rings
- Aluminum centering rings come with Buna-N o-rings
- Allows the mating of two different, but close, sized flanges
| Flange Size | Material | Dim A | Dim B |
| KF10-KF16 | Aluminum | 12,2 | 17,2 |
| KF10-KF16 | Stainless Steel | 12,2 | 17,2 |
| KF20-KF25 | Aluminum | 21,8 | 26,2 |
| KF20-KF25 | Stainless Steel | 21,8 | 26,2 |
| KF32-KF40 | Aluminum | 34,0 | 40,9 |
