Male Coupling for 4 mm Pneumatic Tubing

Spare | replacement male coupling for Air Pressure Controller (APC, VCA002). The male coupling connects quickly and simply to the female coupling on the base of the APC and 4 mm O.D. pneumatic tubing. This enables precise delivery of compressed air or gas into Vivaspin^® 20|100 concentrators, via a charge valve or female coupling (VCA005 or VCA010, respectively), and the appropriate pressure head (VCA200 or VCA800, respectively). It is required for pressurization of Vivaspin^® 20 devices, and also useful when a Vivaspin^® 100 device must have constant pressure applied or cannot be pressurized directly from the female coupling on the base of the APC.
