Stainless Steel Fittings

For Coned Ports

These 316 stainless steel Fittings are rated to 10000 psi (690 bar) when wrench tightened. choose Upchurch scientific® standard Fittings, or select from the Rheodyne® RheFlex® or other manufacturer compatible offerings.

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.

Stainless Steel Nuts and 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.
  4. Using an appropriate wrench, tighten an additional 1/4 - 1/2 turn past fingertight. Remove the fitting to confirm the ferrule is swaged onto the tube.
  5. Because the ferrule is permanently attached to the tubing we highly recommend that the fitting only be used in the mating port into which it was initially swaged. Failure to do this may result in dead volume and/or leaks.
Do not use metal fittings in plastic ports, as this can damage the port.
