JIC Adapters

Parker’s JIC (Joint Industry Conference), also known as Triple-Lok, is the most common fitting on the market. The fitting consists of three pieces: the body, sleeve, and nut. The tube is flared at a 37? angle and held between the fitting nose (seat) and the sleeve (support) with the nut, providing a very effective seal between the fitting nose and the tube flare. The small seal area results in a compact design, low assembly torque, and a relatively high-pressure capability.

The Triple-Lok 2 combines the versatility of stainless steel Triple-Lok with the added advantage of an elastomeric seal. It incorporates an O-ring that is positioned in the nose of the 37? flare so that elastomeric sealing occurs with the mating flared tube. The design is very similar to Triple-Lok, with the O-ring providing improved seal reliability in applications where stainless steel fittings are required.
