Idex Two-Piece Fingertight Fittings

Two-Piece Fingertight Fittings

• Designed to connect tubing to 10-32 coned ports
• Ferrules available for directly connecting 1/16”, 1/32”, 360 μm or 190 μm OD tubing

Two-Piece Fingertight Fittings feature a separate ferrule. With a twopiece design, you can replace just the ferrule instead of the entire unit, making these Fingertights more economical than the onepiece version. Use a standard knurled head fitting for traditional fingertight applications, or use a fitting with wings built into the head for extra tightening leverage. A stainless steel hex headed fitting can be used for applications where a wrench may be needed for added tightening torque.

To order the fittings as shown to the right, simply reference the part numbers as indicated. To exchange the ferrule typically packaged with our fittings with one of our specialty ferrules shown below, simply replace the letter “x” in the part number with a “-01”, and then specify the ferrule needed on a separate line. For example, to order the F-140 fitting with the M-215 ferrule, specify F-140-01 and M-215 separately. Please note: all “-01” fittings are packaged individually, not in 10-packs.

The M-215 Conductive Perfluoroelastomer Ferrule is designed for mass spectrometer electrospray applications. Unlike most graphite ferrules, the elastomeric properties of this ferrule let you use it through many tightening/retightening cycles. It also eliminates any possibility of graphite contamination in your system. Like graphite ferrules, you can apply voltage through a metallic port block or metallic nut, allowing voltage to translate to the flow path through the ferrule.

Application NOTE:

Some Upchurch Scientific® Fingertight Nuts feature wings in addition to a knurled head, which provide more leverage when tightening the fitting into a receiving port. Choose our single or double-winged design.
