We fabricate these KF (QF) tees for HV systems from tubing and KF flanges. The KF (QF) flange is used for through- or foreline vacuum plumbing and for simple HV chamber ports.
KF Tees Feature:
- Available in 304L stainless steel or aluminum 6061-T6 (standard tees only)
- Reducer tees adapt two different flange sizes
- Common lengths and tube diameters listed; contact us with your specific requirements
