RediVac™ Vacuum-Baked O-Rings

UC Components’ RediVac™ O-rings are available in a wide range of Inch-measure sizes for use in HV and UHV applications. Our standard O-rings are made from fluoroelastomer polymer (Viton), in black and brown; Buna, silicone, and other materials are available upon request. Specific chemistries may also be available upon request. Inch O-rings are manufactured to standard AS568A sizes.

Two types of RediVac™ O-rings are available: Cleaned and Vacuum-Baked. Both varieties are specially designed to improve pump-down times and reduce SMC (surface molecular contamination) and VOC (volatile organic contamination—primarily water).

Cleaned O-Ringsundergo UC Components’ proprietary cleaning process, designed to reduce or eliminate surface particulate contamination originating from injection-mold release agents and post-mold handling. All cleaning and packaging is performed in our certified Class 100 cleanroom. This process is based on typical requirements for pre-cleaning elastomer seals prior to installation for vacuum service.

Vacuum Baked O-Rings also go through our precision cleaning process. This is followed by an extended vacuum bake-out process designed to remove trapped water within the O-ring polymer. Vacuum baking reduces water vapor outgassing under vacuum by orders of magnitude. The primary gas load in most vacuum systems is water. Vacuum baked O-rings are then packaged in our Class 100 cleanroom. RGA (residual gas analyzer) data for our vacuum baked O-rings is available for an additional fee.
