Idex - Flat-Bottom Fittings - Metric Flangeless Fittings

Metric Flangeless Fittings offer the same benefits as our Flangeless Fittings with the additional feature of being used for metric tubing and ports. They are specifically designed to connect 1.8, 2.0, 2.5, 3.0, or 4.0 mm outer diameter tubing to flat-bottom ports when paired with the appropriate M6, 1/4-28, or 5/16-24 Flangeless Nuts. We also offer M6-threaded nuts to connect 1/16 inches or 1/8 inches outer diameter tubing, plus a tubing sleeve to facilitate 1.0 mm outer diameter tubing connections.
