Product Description

Product Description

These ISO-K centering rings with mesh are used for mating ISO Flanges and include both the ISO centering ring in SS304 or Aluminium and Viton or NBR o-ring These centering rings with screen mesh are useful in many situations in which a vacuum system or instrument needs to be protected from contamination by particulate generated from outside the system or from within. 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. A circumferential clamp and centering ring form the vacuum seal between the connecting flanges (please see top right figure - click to enlarge). The centering ring contains a rubber elastomer o-ring. The standard sizes for quick flange fittings are KF-10, KF-16, KF-25, KF-40, and KF-50 with flange sizes NW-10, NW-16, NW-25, NW-40, and NW-50, respectively. They are made of corrosive resistant stainless steel with Viton® O-Ring. Viton® is well known for its excellent resistance to heat (400°F/200°C) and to aggressive fuels and chemicals, which are belongs to ISO Vacuum Flanges & Components series, These Vacuum Fittings are made of corrosive resistant stainless steel.
