M.E.C.’s rectangular flexible waveguide is either seamless or sideseam.  Seamless corrugated flexible waveguide is made by convoluting seamless tubing.  Rectangular waveguide sizes larger than WR-137 are made sideseam.  All units are inherently pressure-tight, highly stable, rugged, and have no RF leakage.  They bend more than the flexible-twistable types but cannot withstand any twisting.  Bends are semi-permanent and small bends radii should be factory formed.  Unless requested, units are supplied without jacket or silver plating.

System and laboratory problems associated with shock, vibration, and tolerance take-up caused by misalignment or temperature variations can be solved by utilizing versatile flexible waveguide mediums.

Besides the standard units described on this page, M.E.C. produces many special assemblies such as twists and pre-formed bends to much smaller radii to satisfy unique requirements.  Additionally, combinations of rigid and flexible waveguide, jacketed or un-jacketed, with built-in pressure/relief valves, quick-disconnect flanges, etc., are all readily available.
