Baseplate fittings mount through one inch diameter ports and require a flat, scratch-free sealing surface of at least 1-3/4 inches diameter. A vacuum seal is achieved by uniform compression of an elastomer gasket on the vacuum side of the chamber. A sealing nut and washer are typically fastened on the atmosphere side of the chamber. Hand tightening will usually provide adequate seal compression. Elastomer seals limit the operating temperature range and bakeout temperature. For DuPont Dow Elastomers Viton® O-rings, the maximum intermittent bakeout temperature is 200ºC with a sustained use to 150ºC. Repeated bakeout cycling can result in the deterioration of the O-ring and require its periodic replacement.
