NanoTight Fittings are specifically designed to connect 70 μm–1 mm OD capillary tubing to any standard 10-32 coned port normally intended for 1/16” OD tubing using the NanoTight Tubing Sleeves. The fittings can also be used to connect any 1/16” OD tubing. The Tefzel ®(TEFZEL® (ETFE)) ferrule material is softer than PEEK, making it a good candidate for connecting thin walled semi-rigid tubing such as Dupont® FEP and Tefzel ®(TEFZEL®) into 10-32 ports with minimal constricting to the inner diameter.
