Sealing a vacuum connection remotely in a hostile or radioactive environment can present a difficult challenge for scientists and engineers. This critical application requires easy assembly and disassembly of the flange connection while reducing the number of individual components that must be handled. The QDS or Quick Disconnect System uses a contiguous chain clamp mechanism with two conical flanges and a customized seal that eliminates the need for loose bolts and nuts. In addition, the clamp connection can be fitted to a guide plate that ensures the clamp is always properly aligned. The QDS is of all metal construction and utilizes a spring energized metal seal to provide Helium leak rate performance with little or no permeation or outgassing. Typically, the QDS will require less space than a bolted flange and often requires less torque to create a tight seal.
