Centering ring material: Aluminum or SS304
O-ring Material: NBR or Viton
Size: DN10 - DN50
A KF center ring with an outer ring and O-ring is a type of vacuum seal used in high vacuum systems. It is designed to provide a tight and reliable seal between two KF flanges.
The center ring is typically made of aluminum or stainless steel and is circular in shape. It is placed between two KF flanges to create a vacuum-tight seal. The center ring has a grooved channel around its outer circumference that accepts an O-ring, which provides an additional sealing element. The outer ring, which is also circular, fits over the center ring and is secured in place by bolts or clamps. The outer ring ensures that the O-ring is properly seated in the grooved channel and helps to distribute the clamping force evenly across the flange.
