Triple Lok Fitting

Parkera s triple-lok 37A flare tube fittings have been used in industry since mr. Parker pioneered the product in the 1930s. The 37A flare fitting is the most popular industrial tube/hose fitting connection in the world.today, parker offers a broad range of triple-lok fittings meeting sae j514, iso 8434-2 and military standards and specifications.the triple-lok design is quite simple. The tube fitting consists of three pieces: the body, the nut and the sleeve. The tube end is flared at a mating 37A angle and sandwiched between the fitting nose (seat) and the sleeve creating an effective seal between the fitting nose and tube flare or hose.parkera s triple-lok fittings are manufactured in steel, 316 stainless steel and brass for optimum fluid compatibility and corrosion resistance. Furthermore, available sizes range from 1/8" tube o. D. To 2" tube o. D. In several configurations. Adaptability to global ports is another key benefit of triple-lok. (standard ports include: sae, straight thread iso-6149, npt, bspt, bspp and din. )the triple-lok tube fitting is also readily available for metric tubing and hose adapter applications. Simply by changing the industry standard sleeve, the same triple-lok body can be adapted to metric tubing in sizes ranging from 6 mm tube o. D. To 38 mm tube o. D. Likewise, by using only the body without the nut and sleeve, the triple-lok fitting is used as an industry standard hose adapter.
