VacuTight Fittings are designed to provide
airtight, dependable connections under vacuum and low pressure
conditions. Many of the VacuTight Nuts have streamlined profles for
use in systems requiring a large number of connections in a small
area. Furthermore, the VacuTight Ferrule’s small size ensures suffcient
nut/thread engagement, even in shallow ports. These features make
VacuTight Fittings ideal for “combichem” high throughput screening,
clinical diagnostic and other automated liquid handling applications.
The configuration of the VacuTight flat-bottom ferrules prevents
overcompression and tubing ID reduction that can occur with many
coned fttings. The result is more consistent aspirating and dispensing
volumes across all system connections.
The VacuTight fttings can also work well in some positive pressure
applications. The pressure range for each ftting is listed below and
depends upon the tubing used for the connection. Please contact
your distributor or IDEX Health & Science for more information.
Additionally, please note that some of the VacuTight fttings have
changed in color from red to black; however, this color change does
not affect product performance.
All VacuTight Nuts must be used exclusively with VacuTight Ferrules.
