We fabricate these KF (QF) nipples (spools) 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.
Half nipples feature one KF flange
Full nipples feature two KF flanges
Conical and straight reducer nipples 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.
