Flangeless Fittings

Upchurch Scientific® Flangeless Fittings eliminate the need to flange tubing. This removable and reusable system provides several benefits:

Convenience: Flangeless Fittings are easy to use. Just slip the nut and ferrule over the tubing and finger tighten the assembly into your receiving port. In tests, it is shown that the ideal amount of torque to achieve expected part performance should be approximately 3 – 4 in-lbs (0.34 – 0.45 N·m). Check out the line of special tightening tools designed to adapt to many standard torque wrenches, on page 33 and the new adjustable torque driver, VHP-4000.
Minimal Down-Time: Component replacement is quick, taking only a few seconds — unlike the significant time required to flange tubing.
Cost-Effectiveness: Repairing a flanged tubing assembly requires a costly flanging tool or the purchase of a complete replacement assembly, including a new length of tubing and a set of fittings. The Flangeless Fittings system typically requires only one new ferrule at minimal cost when repairing a connection.

The 1/4-28 and M6 Flangeless Fittings for 1/16”, 1/8” and metric sized OD tubing are summarized on this page.
