Parker Hannifin Tube Fittings” Triple-Lok swivel connection is a 37-degree flare female with the sealing location positioned away from the tip of the male nose. The new sealing position better tolerates surface imperfections at the tip, helps protect the nose during assembly, and prevents it from gouging the female cone seat. Tested to provide increased pressure ratings in most sizes, the Triple-Lok swivel connection can eliminate the need for a bulkier, swivel fitting (nonstandard) in order to meet higher pressure requirements. Features a dual-angle seat that accepts both 37-degree and 45-degree flare fittings (in certain sizes). There is no difference in overall swivel nut size or fitting body, and no change in torque or assembly method. Pressure ratings are 72 percent higher than SAE J514.
