Reducing ferrulesprovidean
inexpensiveway toconnect small
temporary transfer lines tovalvesor

For long termuse,we recommend
our reducingunions, internal reducers

ZDV reducing ferrulesare
designed forusewithall standard
external stylefittings– that is, those
witha femalenut andamalefitting
detail. This ferrulehasa slightly longer
pilot than the internal version, to
accommodate the longer external
detail. The result isazerodeadvolume
fitting. A singlegroove indicates that
the ferrulehas the longerpilot and is
foruse inanexternal detail.
