Flanged Fittings

For Flat-Bottom Ports

  • Interchangeable with Cheminert® and Omnifit® Fittings
Upchurch Scientific® 1/4-28 Flanged Fittings are compatible with most standard flanged fittings. The hard, inert Delrin® (acetal resin) nut resists cross threading or loosening during use, while the Tefzel® (ETFE) nuts work well in chemically aggressive environments. The nuts are interchangeable with Cheminert and Omnifit fittings.

Each color-coded Flanged Fitting is shipped with a stainless steel washer to ensure a good seal and firm connection in any flat-bottom port. For an alternative to flanging tubing, we highly recommend the Flangeless Fittings, the Super Flangeless™ Fittings, or the VacuTight™ Fittings.
