KF centering ring is used for mating KF flanges and include both the centering ring and o-ring. Within critical semiconductor vacuum environments, KF centering ring seal assemblies can maintain a reliable, effective vacuum seal. In order to assure maximum seal performance, o-rings on these assemblies provide low compression set and high retained resiliency. Our KF centering ring with o ring have excellent compression set resistance and high performance physical properties, contact us for price!
Application: High and ultra-high vacuum apparatus, semiconductor, aerospace etc.
