Reducing ferrules provide an inexpensive way to connect small temporary transfer lines to valves or fittings designed for larger tubing. For long term use, we recommend our reducing unions, internal reducers (IZRs), or external reducers (EZRs), as appropriate.
Internal reducing ferrules
Internal ZDV reducing ferrules are designed for use with all standard Valco internal style fittings - that is, those with a male nut and female fitting detail.
External reducing ferrules
External ZDV reducing ferrules are designed for use with all standard external style fittings - that is, those with a female nut and a male fitting detail.
Standard reducing ferrules
Standard reducing ferrules can be used where mixing is not a problem, such as with liquid or gas delivery. A 1/16" to 1/32" ferrule of this style is simply a 1/16" ferrule with a 1/32" hole.
