Two-Piece SealTight™ Fingertight Fittings for 1/16" OD Tubing - Nuts and Ferrules

For Coned Ports

  • Hold up to 9000 psi (620 bar) with Fingertight Convenience.
The dual compression created by the specially designed nut and ferrule enables the Upchurch Scientific® SealTight Fittings system to outperform standard finger tightened fittings. The forward cone of the SealTight Ferrule provides gripping power and a leak-free seal via conventional compression by the receiving port. The slotted end creates the second compression zone in conjunction with a SealTight Nut. (The SealTight Ferrule design is similar to that of the RheFlex® Two-Piece Ferrule). All SealTight Nuts are for use with 1/16" OD tubing and are designed to be used with the F-192 Ferrule. This fittings system is also interchangeable with Two-Piece RheFlex Fittings System.

Try our F-350 FlushNut™ for the ultimate streamline design.

Installing High Pressure Fittings

Before connecting fittings, ensure the end of the tubing has a clean, square, burr-free cut. This is very important, as the square cut helps the tubing make full contact with the bottom of the mating port. Neglecting to properly cut the tubing could lead to dead volume, resulting in peak distortion such as fronting, tailing or broadening.

Two-Piece Fittings with Polymer Ferrules
  1. Slide the nut, followed by the ferrule, at least 3/16” from the end of the clean cut tubing.
  2. Insert the assembly into the receiving port, pushing the tubing into the port until it bottoms out.
  3. Finger tighten the nut into the port until snug.(Upchurch Scientific® recommends a tightening torque of 2-4 in-lbs for its Fingertight fittings - roughly equivalent to typical finger tightening torque. Please note that undertightening can result in fitting leakage at pressures less than to what the fitting is rated, and overtightening can cause leakage and/or fitting damage.)
  4. After several uses (especially at high pressures) the ferrule should be replaced.
