Upchurch Scientific® VacuTight Fittings are designed to provide airtight, dependable connections under vacuum and low pressure conditions. Many of the VacuTight Nuts have streamlined profiles for use in systems requiring a large number of connections in a small area. Furthermore, the VacuTight Ferrule's small size ensures sufficient 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.

VacuTight Fittings are available for flat-bottom 10-32, 1/4-28 and M6 threaded ports. The configuration of the VacuTight flat-bottom ferrules prevents over compression and tubing ID reduction that can occur with many coned fittings. The result is more consistent aspirating and dispensing volumes across all system connections.

The 10-32 VacuTight Fittings are for use with 1/16" OD tubing. The 1/4-28 and M6 fittings are available for use with both 1/16" and 1/8" OD tubing. All VacuTight Nuts must be used exclusively with VacuTight Ferrules.

VacuTight Nuts with hex heads can be tightened with a standard 1/4" wrench. All VacuTight Nuts with knurls (finger grip ridges) can be tightened finger tight. Additionally, some of the standard head and headless nuts can be tightened with our Extender Tools. We recommend tool tightening no more than a 1/2 turn past finger tight.

Use any of the 10-32 fittings on this page to make an inline connection with our VacuTight Union. This product is designed for use with 1/16" OD tubing. Or, use your choice of 1/4-28 or M6 VacuTight Fittings with the appropriate union from page 64 to make an inline connection with 1/16" or 1/8" OD tubing.
