O-rings are most often the primary source of contamination in any vacuum system. Selecting the proper O-ring design and material are essential to maintaining the seal and overall system integrity. Unfortunately, you cannot simply rely on the property values you get for the elastomers when selecting an O-ring for your clean-critical application; vacuum performance of the material can differ strongly from supplier to supplier, as well as batch to batch.
