Centering Rings

Within critical semiconductor vacuum environments, KF centering rings must maintain a reliable and effective vacuum seal.  In order to ensure maximum seal performance, the o-rings on these assemblies must provide low compression set and high retained resiliency.  CrestTec’s full range of KF type centering rings are available in all standard ISO sizes with a choice of either stainless steel or aluminum.  We offer them with a wide variety of o-ring compounds suitable for different semiconductor manufacturing processes.  Including silicone, fluorocarbon/FKM, HiFluor, and FFKM/perfluorinated elastomers for high purity, aggressive chemistries, and extreme temperatures.
