Flare Fittings

1. Assembly

• Cut the tubing squarely and clean the end thoroughly to remove burrs.
• Place the nut onto the tube with the threaded end facing the tube end.
• Use a flaring tool to create a 45° flare at the tube end.
• Clamp the flared tube end between the nut and the fitting body. Tighten the nut finger-tight, then secure it with a wrench for an additional 1/4 to 1/2 turn to ensure a leak-proof metal-to-metal seal.
• Flare fittings are easy to disassemble and can be reassembled repeatedly, maintaining a leak-proof connection.

2. Material Specification

• Free cutting IS-319/CZ-121
• CA360 Brass for bar stock fittings
• CA377 Brass for forged fittings
• Lead-free, DZR, bronze, and other special copper alloys as per customer specifications.

3. Threads

• UNFE, BSPT, BSP, NPT, and any special thread as per customer specifications.

4. Pressure

• Working pressure up to 2000 PSI, depending on the tubing used.

5. Temperature Range:

• -65°F to +250°F (-53°C to 121°C) at maximum operating pressure (refer to tubing temperature range).

6. Vibration Resistance

• Good vibration resistance; use long nuts for greater vibration resistance.

7. Finish and Coating

• Natural brass
• Nickel-plated
• Tin-plated
• Special plating as per customer requirements

8. Standards

• Conforms to SAE, ASA, and ASME specifications.

9. Applications

• Copper, brass, aluminium, and steel tubes that can be flared.
