4-Way KF (QF) Crosses
We fabricate these KF (QF) crosses 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 Crosses Feature:
- Available in 304L stainless steel or aluminum (4-way standard crosses only)
- Reducer crosses adapt two different flange sizes
- Common lengths and tube diameters listed; contact us with your specific requirements
NOTE: These flanges are identical to the ISO NW flange standard. While these flanges are compatible with those made by European manufacturers, the tube diameter listed is in inches.
