ChillWaves Brass Flare Tube Fittings, SAE 45 Degree 3/4" Flare Nut Air Conditioning Copper Tube Extension Butt Copper Pipe(3-PACK)

ChillWaves Brass Flare Tube Fittings, SAE 45 Degree 3/4" Flare Nut Air Conditioning Copper Tube Extension Butt Copper Pipe(3-PACK)

• SIZE - 3/4" Flare Nuts. Flare end is SAE 45 degrees, please refer to the dimension drawing for specific diameter.
• MATERIAL - Made of high-quality brass, with strong wear and corrosion resistance, high compressive strength, durability, low magnetic permeability and high temperature ductility.
• USE - Suitable for gas, instrumentation, refrigeration, vacuum lines, power steering, hydraulic and pneumatic systems, manufactured for low and medium pressure piping connection engineering.
• WORKING PRESSURE & TEMPERATURE - 1200PSI maximum working pressure, temperature range -65°F to +250°F (-53°C to +121°C)
• WORKING PRINCIPLE - The end of the tube is flared to a 45° angle, creating a sealing surface that mates with the fitting's cone. When the nut is tightened, the flared tube is compressed against the cone, forming a leak-proof metal-to-metal seal. This design offers advantages including temperature and pressure resistance, excellent sealing performance, reusability, no welding required, easy disassembly and assembly, and straightforward installation and maintenance.
