Flangeless SealTight Fittings

For Flat-Bottom Ports

  • Hold up to 5,000 psi in 1/4-28 Flat-Bottom Ports
  • All Polymer construction
The Upchurch Scientific Flangeless SealTight Fittings system has redefined the pressure range of metal-free applications for traditional 1/4-28 flat-bottom ports. Our innovative F-290 Ferrule incorporates the dual compression mechanism of the F-192 coned SealTight Ferrule in a design that allows its use in a flat-bottom port. With this ferrule and a Flangeless SealTight nut, it is now possible to hold pressures up to 5,000 psi (345 bar) with all-polymer components in flat-bottom ports.

All Flangeless SealTight nuts require the PEEK F-290 Flangeless SealTight Ferrule. This fittings system, for use with 1/16" OD Tubing only, is particularly well suited for applications where metal is undesirable, such as those involving NMR or microwaves.
