1/8" PP orange head nut (1/4-28UNF male) 10 pcs OM2620N 1 bag (10 pcs)

Basically, they are for use with fluororesin tubes and PEEK tubes with outer diameters of 1/16" and 1/8", and are used in combination with a head nut and inverted cone for the connecting tube size, with the exception that the polypropylene (PP) head nut for 1/8" tube is also compatible with tubes with outer diameters of 2.0, 2.5, and 3.0 mm. There is no need to create a flange (flare) at the tip of the tube. Simply insert the tube into the separately sold ETFE inverted cone for the outer diameter of the tube and connect it together with the head nut to a flat bottom port with a 1/4-28 UNF female or M6 x 1 female thread to create an inert connection. The tube connection pressure resistance is generally 1.7MPa. There are two types of head nuts, made entirely of PEEK and entirely of polypropylene (PP), and there are four different head shapes.
