Application Note of Flangeless Fittings


1. Choose 1/4-28 nut when receiving port is 1/4-28; Choose M6 nut when receiving port is M6.

2. 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.

3. Two-Piece Fittings Installation Steps:

a. Slide the nut, followed by the ferrule, at least 3/16” (4.7625mm) from the end of the clean cut tubing

b. Insert the assembly into the receiving port, pushing the tubing into the port until it bottoms out.

c. Finger tighten the nut into the port until snug.

d. After several uses (especially at high pressure) the ferrule should be replaced.
