New Line of Vacuum Connectors.--Central Scientific Company announces a new line of precision-built connectors for joining tubular elements in vacuum systems. Type CHV is for making a vacuum-tight metal-to-glass connection and is especially useful for making a leak-proof seal with the glass stem of a thermocouple, Pirani, ionization or other type vacuum gage. Type CHV is hand-tightened, requiring no special wrench, and permits rapid connection or disconnection of vacuum systems. The "O" ring, which compresses to make the positive seal, is of special composition suitable for high vacuum use and temperatures to 200 ยฐ F.
This new line also includes metal-to-metal connectors fitting standard tubings of steel, stainless steel, copper, etc.
The Cenco Universal Vacuum Release Valve is designed to provide a fast and convenient means of admitting air to a vacuum system. It may be connected by welding, brazing or soldering to the metal tube of the vacuum system and, if desired, may be mounted on a panel or through a plate.
