When reducing the number of elements, a “dummy” or non-functional element can be used to fill unnecessary element mounts. Our “dummy” elements are carefully machined from high grade aluminum and designed to replace any brand of 2” outside diameter element in any vessel. The seal is a Viton o-ring. Includes an adjustable center “rest” to allow easy installation in vessels with element aligning guides. Needs no additional hardware, works with cover interlocks.
