Tube extension WET-18-A

The WEB and WET extension tubes allow or easier pass through of fiber through think walls and penetrations. WEB tubes are made of brass and have external threads which match the WGF-6, WGF-461 and WGF-4. They require a WCN-6 Waveguide Coupling Nut to attatch them to the Waveguide Filter. The WET tubes are made of PVC and are internally threaded. These attach directly to a the Waveguide Filters without the need for a separate coupling nut. The WET-18-A fits the WGF-6, WGF-461 and WGF-4 while the WET-18-B fits the WGF-12.
