What is CF flange?
ConFlat (CF) fittings are flanges which utilize metal seals to attain vacuum conditions. The combination of a stainless-steel knife-edge flange and a copper gasket (OFHC) makes for a nearly impenetrable vacuum barrier. CF flanges use a series of bolts, unlike other vacuum seals that use clamps and elastomers.
How does a ConFlat flange work?
CF (ConFlat) flanges use an oxygen-free high thermal conductivity copper gasket and knife-edge flange to achieve an ultrahigh vacuum seal. Deformation of the metal gasket fills small defects in the flange, allowing Conflat flanges operate down to 10−13 Torr (10−11 Pa) pressure.
How do you tighten a CF flange?
Apply a wrench to both the bolt head and the nut. Tighten by turning the nuts in small increments (1/2 turn or less) using the alternating pattern shown in the diagram, choosing a bolt across the flange from the last. Continue the incremental tightening of the nuts until the desired torque pressures have been achieved.
What is a KF flange?
KF flanges are ISO-standardized vacuum fittings that provide a vacuum seal by compressing a rubber O-ring between two mating surfaces. Also referred to as NW, QF, or DN flanges, KF flanges are ideal for quickly assembling vacuum systems thanks to their ease of use, maintenance, and reusability.
What is LF flange?
The ISO large flange standard is known as LF, LFB, MF or sometimes just ISO flange. A larger version of the KF (QF) flanges, the flanges are joined by a centering ring with an elastomeric o-ring seal. ISO stainless steel vacuum fittings are for tube sizes ranging from 2-1/2″ through 24″ diameters.
What is NW25?
Vacuum Fittings in size NW25/QF25/KF25 and ISO25. This is a modular snap together approach to assembling any vacuum fittings systems. Good for use with pumps and systems to 1×10-6 Torr. Industry standard.
What is ISO-KF?
The ISO-KF system is a family of small vacuum components up to 2” that include flanges, elbows, tees and crosses. The International Standards Organization (ISO) defines the interface dimensions, allowing the interchanging of components that conform to the standard’s dimensions.
What is ISO KF?
What is ISO flange?
ISO HV Flanges (also called Large ISO) have a sexless design and are made from 304L stainless or aluminum. Each flange face is counter-bored or grooved to receive a metal centering ring with an elastomeric o-ring around its O.D. As with KF, the ISO centering ring both aligns the flanges and holds the o-ring in place.
What is KF 25?
KF25 (NW25) Blank Flange Vacuum Fitting – Stainless Steel Cap – Stopper. These Blank Flange fittings follow ISO-KF standards. They are commonly used to build foreline vacuum plumbing and process systems. They are often called quick flange fittings because they are quick to assemble.
What skin tone is NW25?
