Super Flangeless™ fittings

Product / Chromatography

The IDEX Super Flangeless™ Fittings are unmatched in sealing performance and pressure tolerance for flat-bottom ports. A biocompatible ferrule seals the liquid path and a lock ring holds it in place; the connection holds tight through vibrations and the nut can be tightened without twisting the tubing. Nuts of PEEK, PPS, PFA or stainless steel are available for 1/4-28 and M6x1 as well as 10-32, 6-32, 6-40 and 5/16-24 ports.
