The MicroTight® components
To make a perfect connection, the system usually consists of three parts:
- MicroTight Nut: The nut that provides the pressure.
- MicroTight Ferrule: The specific small ferrule that seals the tubing.
- MicroTight Tubing Sleeve: A protective sleeve slid over the capillary tubing to increase the diameter to a size the ferrule can grip.

Instructions for use & tips
First, slide the SealTight nut over the tubing, followed by the SealTight ferrule. Then insert the tubing into the port until it bottoms out. While holding the tubing in place, tighten the nut finger-tight.
Important: For an optimal seal we recommend using the matching SealTight ferrules; these are specifically shaped to work with the internal geometry of the SealTight nuts.
