MicroTight® fittings
Comprehensive fitting system for capillary tubing
MicroTight® One-Piece fittings are designed for use with the NanoPort™ and MicroTight® unions, adapters and inline microfilters. Specifically made for 360 µm OD tubing, 1/32” OD tubing, or IDEX MicroTight® tubing sleeves (0.025” OD), these fittings make superior fingertight connections with capillary tubing into 6-32 coned ports.
The MicroTight® family also includes a female nut matched with one of five dedicated ferrules for connecting specific tubing ODs into 5/16-24 coned ports. While the female nuts may be used with any of the separate MicroFerrules, the MicroFerrules themselves are port-specific and are thus not interchangeable.
MicroTight® fittings are constructed from PEEK, pressure rated to 4,000–5,000 psi (276–345 bar), and can withstand temperatures up to 125 °C. Some of these fitting designs are also available in IDEX proprietary PEEK blend (PK). These MicroTight® VHP PK fittings are pressure rated to 15,000 psi (1,035 bar) and can tolerate temperatures up to 200 °C.
