Specification:
Material: They are made of resistant stainless steel.
ISO-KF Flange Size: NW-10;A = 30 mm, B = 12.20 mm, C = 13 mm (0.52 in.), D = 15.50 mm, E = 12.70 mm
ISO-KF vacuum flange components are joined by inserting a centering ring seal between the two flange faces, then securing the assembly with a flange encompassing clamp.
The two-part, bolted clamp fits over the flange with a centering ring assembly used between the flange and the opening.Bulkhead flange clamps attach an ISO-KF flange directly to a chamber or base plate. 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.
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.
