Idex Super Flangeless Fittings

Super Flangeless™ Fittings

  • Designed to hold to higher pressures than standard flangeless fittings
  • Eliminates loosening of nuts caused by tubing twist

The design of the Super Flangeless fitting system includes a two-piece ferrule with a lock ring which operates as a bearing against the nut. The nut can then spin freely without turning the ferrule while rotating, preventing the tubing from twisting during the tightening process. This feature helps eliminate subsequent loosening of the nut, making the Super Flangeless system ideal for applications subject to vibration. These products are also well suited for connections that need to be broken frequently, since the lock ring holds the ferrule in place on the tubing until intentionally removed. Use the LT-300 Removal Tool to release Super Flangeless Ferrules from tubing for repositioning.

The fittings systems on this page connect 1/16” OD tubing into any flatbottom 6-40, 6-32 or 10-32 flat-bottom port. Use the FEP NanoTight™ Sleeves with these fittings to connect capillary tubing with OD sizes between 70 μm and 1 mm. Choose from a variety of nut styles for the 10-32 nuts, depending on the application. The headless 6-40 and 6-32 nuts can be tightened using the N-290 extender tool.

  • 1/4-28 and M6 flat bottom fittings for 1/32” or 1/16” OD tubing
  • Fitting system designed to not loosen during vibration

With the benefits mentioned on the previous page, the Super Flangeless Fittings for 1/4-28 or M6 flat bottom ports are quickly becoming the standard for instrumentation, displacing many flanged tube assemblies. Once swaged, the fitting system is perfect in applications where repeated connections are required. Unlike with flanged tubing, the Super Flangeless fittings withstand several retightening cycles with no change in performance or damage to the tubing. Find a variety of nut styles and materials on this page, plus contact your local distributor or us for additional nut colors.

  • 1/4-28 and M6 flat-bottom fittings for 1.8 mm or 1/8” OD tubing
  • M6 flat-bottom fitting for 2.0 mm OD tubing
  • Pressure rated up to 2,500 psi (172 bar)

These fittings offer all of the benefits of Super Flangeless Fittings for 1.8 mm, 1/8” or 2.0 mm OD tubing. Due to the double compression by the lock ring and ferrule on the tubing, this fitting system boasts the highest pressure rating for 1/8” OD tubing into flat-bottom ports. These fittings can be used in any of the IDEX Health & Science products featured in the catalog with a 1/4-28 or M6 flat-bottom port for increased pressure holding ability. A variety of nut styles and materials are available, plus contact us for additional nut color options.

Please note the design of the Super Flangeless Fittings for 1/8” OD tubing prevents them from being used in shallow ports. For these applications, we recommend using the small valve Flangeless Ferrule.
