UC Components, Inc. RediVac® O-rings are specially processed for use in High Vacuum and Ultra High Vacuum equipment. All of our O-rings are cleaned and packaged in a certified Class 100/ISO Class 5 Cleanroom, making them suitable for immediate use in HV, UHV, or EUV applications.

UC Components, Inc. RediVac® O-rings are available in a wide range of standard AS568A inch-measure sizes.

Our standard O-rings are manufactured from top quality fluoroelastomer materials. Buna, silicone, and other materials are available upon request. Specific chemistries may also be available upon request.

We offer two types of RediVac® O-rings: 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-Rings undergo UC Components, Inc. 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/ISO Class 5 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/ISO Class 5 Cleanroom. RGA (residual gas analyzer) data for our vacuum baked O-rings is available for an additional fee.
