External Reducing Ferrule 1/8 to 1/16'', PEEK, 5 pc/PAK

External zero dead volume reducing ferrules are used with all standard external style fittings, which have a female nut and a male fitting detail. This ferrule has a slightly longer pilot than the internal version to accommodate the longer external detail, resulting in a zero dead volume fitting. A single groove indicates that the ferrule is for use in an external detail.
