Flangeless Omni-Lok™ fittings from Bio-Chem Valve/Omnifit are designed to connect to shallow ¼”-28 UNF PTFE ports, such as those in solenoid valves. They are also available as part of a pre-assembled PTFE tubing set to be used in laboratory instruments. Distinctively colour-coded, Omni-Lok™ fittings permanently fit to one or both ends of 1/16″ and 1/8″ O.D. sized tubing. The fittings consist of a robust, glass-filled polypropylene fitting nut and a PTFE, PEEK™ or Tefzel® ferrule, with a stainless steel lock ring. This provides a finger-tight seal ideal for use in solenoid valve ports and other shallow PTFE ports. The permanently attached ferrules and freely spinning fitting nuts are designed to allow repeated connecting and disconnecting to ¼”-28 UNF ports.
