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. The KF designation has been adopted by ISO, DIN, and Pneurop.

Are NW and KF flanges the same?

NW (also known as KF & QF) NW Vacuum Hardware is known also as KF and QF. NW Vacuum Flanges and Fittings are quick release and are great in rough vacuum to high vacuum applications. NW Fittings are quick and easy to use and assemble into a vacuum system.

What size is KF25?


KF16/30mm Tube OD: 3/4″, Flange OD: 1.18″
KF25/40mm Tube OD: 1″, Flange OD: 1.57″
KF40/55mm Tube OD: 1-1/2″, Flange OD: 2.16″
KF50/75mm Tube OD: 2″, Flange OD: 2.95″

What is ISO K flange?

An ISO-K and ISO-F compound consists of two symmetrical flanges and one O-ring seal, which is positioned and supported with an inner centering ring and also supported by an outer ring. The required contact pressure for sealing, is created with double claw clamps (Figure 3.9) or screws (Figure 3-13).

What is an ASA flange?

ASA (ANSI) vacuum flanges provide a complete range of fittings to mount with tubing sized from 1 to 12 inches in diameter. The flange system consists of two flanges, a sealing ring, and bolt fasteners to compress the seal between the two flanges.

What is CF gasket?

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.

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 the difference between ASA and ANSI?

The ASA began to develop partnerships with global organizations, such as the ISO and helped promote U.S. standards internationally. In 1969, the ASA was renamed to ANSI. For the past several decades, ANSI has continued to promote both national and international standards.

What is 150 ASA flange?

ASA 150 gaskets are some of the most commonly used sizes of standard pipe gaskets. ASA 150 gaskets can be manufactured either as IBC gaskets (sitting inside the bolt circle of the flange) or as full faced gaskets (with bolt holes) to cover the face of the flange.

What is ISO flange?

ISO HV Flanges (also called Large ISO) have a sexless design and are made from 304L stainless or aluminum. The design principles of ISO and KF seals are identical. Each flange face is counter-bored or grooved to receive a metal centering ring with an elastomeric o-ring around its O.D.

What is an ISO flange?

What does ASA 150 mean?

What is a CF flange?

What is a kf40 profile?

KF40® combines the performance of a traditional flat pan profile with the unmatched economy and concrete saving of a trapezoidal deck. No end caps needed. Also provides rigid and secure platform during construction.

How do I install kf40® on a wall?

Place the KF40® sheet over the supports ensuring a minimum end bearing of 50mm. If supporting on a brick or masonry wall, provide a separating strip such as malthoid. Engage subsequent sheets of KF40® by locking the larger female rib over the male rib as shown in the diagram below. No crimping is required in this situation.

What is the BMT of a kf40?

KF40® is manufactured from G550 (550 MPa Yield Stress) steel in a 3 pan profile with a Base Metal Thickness (BMT) of 0.75mm and 1.00mm. The galvanised coating thickness is a Z350 (350 g/m2) in accordance with AS 1397:2001.
