JIC Nuts, Sleeves & Locknuts | Parker Triple-Lok

Parker Triple-Lok JIC tube fitting design is simple. The tube fitting consists of three pieces: the body, the nut and the sleeve. The tube end is flared at a mating 37 degree angle and sandwiched between the fitting nose (seat) and the sleeve. This creates a very effective seal between the fitting nose and tube flare, or hose.

Although most JIC fittings are commonly viewed as 3,000 PSI connectors, Parker Triple-Lok JIC flared fittings are rated at 9,000 PSI for 1/4" size to 2000 PSI for 2” size. Parker JIC 37 degree flare fittings are manufactured in steel, 316 stainless steel or brass, and are available from Hose & Fittings, Etc.
