What is KF flange?

KF HV flanges (Figure 1) are a sexless design—made from 304L or 316L stainless, aluminum, or brass. The name KF (for Klein Flansche) was adopted by ISO, DIN, and Pneurop standards organizations. It is also called QF, NW, and occasionally, DN.

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 does NW flange stand for?

quick release flange
The ISO standard quick release flange is known by the names Quick Flange (QF), Klein Flansche (KF, German which translates to “Small flange” in English) or NW, sometimes also as DN. Standard sizes are indicated by the nominal inner diameter in millimeters for flanges 10 through 50 mm in diameter.

What is ConFlat gasket?

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. Depending on the application, CF fittings can be supplied with both through-bolt and threaded holes.

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. Pumps connecting to just about any equipment. Good for use with pumps and systems to 1×10-6 Torr. …

What is a ConFlat?

ConFlat (CF) UHV Flanges. The CF flange (originally called ConFlat) is a sexless design where both flanges are identical. Typical flange materials are austenitic stainless steel types 304L, 316L, 316LN, and surface hardened aluminum (made from a weldable Al alloy).

What is NW50?

Vacuum Fittings in size NW50/QF50/KF50 and ISO50. This is a modular snap together approach to assembling any vacuum fittings systems. Pumps connecting to just about any equipment. Good for use with pumps and systems to 1×10-6 Torr. …

Is KF the same as NW?

No, NW, KF (from Klein Flansche) and QF are the same types of vacuum flange systems. KF is the more popular European term, while NW is more popular in North American. QF in reference to Quick Flange, is descriptive of the type flange system.

What size is NW25?

What are Conflat flanges?

ConFlat (CF) fittings are flanges that use –metal seals to achieve vacuum conditions. The combination of a copper gasket (OFHC) and a stainless steel knife-edge flange makes for an almost impenetrable vacuum barrier. This guarantees a strong and uniform seal across the copper gaskets.

What is the meaning of flanged?

1 : a rib or rim for strength, for guiding, or for attachment to another object a flange on a pipe a flange on a wheel. 2 : a projecting edge of cloth used for decoration on clothing a jacket with flange shoulders.

What are KF vacuum flanges?

KF flanges utilize an aluminum clamp with a single wing nut clamp allowing frequent disassembly without tools. The degree taper surface of flanges allows uniform pressure for compressing an O-ring held in place by a centering ring. The vacuum seal can be applied up to 1 x 10-9 mbar, depeding on gasket material,and baked to 200°C.

What is vacuum flange?

A vacuum flange is a flange at the end of a tube used to connect vacuum chambers, tubing and vacuum pumps to each other.
