For flangeless connections, use VICI Jour PEEK flangeless nuts, in combination with our inverted ferrules.
With excellent chemical resistance, they are compatible with all ¼-28 flat-bottom ports for 1/16” or ⅛” OD tubing. They are true fingertight nuts—no flanging tool required. When used in combination with our inverted ferrule, a hand-tightening procedure makes leak-free seals.
With this fitting system, the inert ETFE ferrule is the only part besides the tubing that comes into contact with the fluid stream—never the nut.
Ferrules are not included, order separately.
