FLUID POWER 2 Brass Fittings
FITTINGS — BRASS SAE 45° FLARE TUBE
Typical Applications Pressure
LP and Natural Gas, Flammable Liquids, Instrumentation, Refrigeration, Power Steering, Hydraulic and Pneumatic systems. Up to 2000 PSI depending on tube size. 2-Piece Flare Good Resistance - use long nut when greater vibration resistance is required. -65°F to +250°F CA360 Brass Copper, Steel, Aluminum and Bundy Tubing Low cost and reusable, long or short nut available. Good resistance to vibration. Listed by Underwriters Laboratories for flammable liquids, refrigeration and gas. (Available on Special Order). Meets specifications and standards of ASA, ASME & SAE. Nut has concave turn behind hex. Is a two piece fitting - a nut and a body. Look for a 45° flared end on the fitting body. The nut has a tapered seat to nest the flared tubing in.

Fitting measurements are called out by the tube size first and then the pipe size (if one). * (A) The fastest way to identify the tube size is to measure the tube opening (A) of the nut with your brass gauge or caliper. * (B) If the nut is not available, measure the diameter of the threaded section on the tube size and then use the above chart to convert the thread size to the tube size. Your brass gauge also has this chart on it. *Use the 1/4” method, measure the OD of the threaded end, subtract 1/4” from the measurement to find the Pipe Size.
