What is ISO KF?

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 an ISO KF flange?

ISO-KF flange vacuum components provide a modular, building block method for creating 0.75 to 4 inch vacuum piping systems. They use standardized dimensions allowing ISO KF fittings or valves of the same size to be interchanged. ISO-KF flanges are also sexless with a symmetrical seal so components can be rotated.

What is KF fitting?

This KF flange is a ISO-standardized vacuum fitting that can be mated to a vacuum system using a wing nut clamp and an O-ring carrier (sold below). The angled sides of the wing nut clamp compress the O-ring between the flanges, quickly creating a vacuum seal.

What is a KF 16 fitting?

KF-16 T Fitting These KF-16 T fittings follow ISO-KF standards and have a flange size of NW-16. They are most often used for foreline vacuum plumbing and process systems, often called quick flange fittings because they are quick to assemble.

What is ConFlat flange?

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 an NW flange?

NW (also known as KF & 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. Sizes range from 10 mm (NW1o) to 50 mm (NW50). Seals are reusable and bakeable to 150C with Viton o-ring seals.

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 KF 50?

These KF-50 Hinge Clamp vacuum fittings follow ISO-KF standards and have a flange size of NW-50. 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.

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 is the difference between KF and NW flanges?

Each vacuum seal is made by compression of an O‐ring on a centring ring between mating flanges. The seal is made in seconds by finger‐closure of a wing nut on the all‐metal hinged swing clamp….Klein Flange (DN/NW/KF ISO‐KF)

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.

Are ASA and ANSI flanges the same?

ASA/ANSI flanges are available in two general styles: fixed and rotatable. Fixed flanges have a set bolt hole orientation while rotatable flanges have a two piece design allowing for bolt hole rotation to ease bolt alignment when mating the two flanges.
