However, the following table is a good guide for proper selection. Temperature 73 o F with copper tubing: •Vibration Excellent resistance. •Temperature Range -650F to +2500F (-530C to +1210C) range at maximum operating pressures. •Material CA360 Brass. Actual O.D. of male inverted flare threads •Used With Copper, brass, aluminum and steel hydraulic tubing that can be flared •Advantages Very low cost and reusable. Seats and threads are internal and protected. Compact, excellent vibration life. Short nut affords very close tube bends. Steel or brass tube nut. •Conformance Meets specifications and standards of ASA, ASME, SAE, and MS (Military standards). •Assembly Instructions 1- Cut tubing to desired length. Make sure all burrs are removed and ends are cut square. 2- Slide nut on tube. Threaded end “A” of nut must face out. 3- Flare end of tube with a 45 o flaring tool. a-Measure flare diameter b-Examine flare for excessive thin out. c-On thin wall, welded or brazed tubing, use double flare to prevent pinch-off and cracked flares. 4- Lubricat threads and assemble to fitting body. Nut should be turned hand tight. 5- Tighten assembly with wrench until a solid feeling is encountered. From that point, apply a one-sixth turn. Note: Do not over-torque as it may damage the fitting or split the tubing at the flare. Tube O.D.
