ABSTRACT:
A waveguide seal assembly for a waveguide joint is fabricated in separate parts, including a relatively small inner conductive part for surrounding the coupled waveguide openings in the joined waveguide flanges of two joined waveguide sections, an outer conductive part having a central opening which permits the outer part to fit over the inner part such that an intermediate gap is formed between the inner and outer parts, and a gas sealing element, suitably in the form of an O-ring, fitted into this intermediatex gap. Preferably, an O-ring groove is provided on the outer perimeter of the inner conductive part for retaining the O-ring when the seal assembly is installed. Also, preferably the inner conductive part is slightly thicker than the outer part to ensure good electrical contact at the coupled waveguide openings.
