When choosing Flare Fittings, you must consider multiple factors to ensure that the accessories you choose not only meet the system requirements, but also ensure safety and stability in long-term use. The following are several key points that need special attention when choosing Flare Fittings:

Pressure level: Choose SAE, JIS or DIN standard products according to the system working pressure

The choice of Flare Fittings must first be determined based on the system's working pressure. Different Flare Fittings have different pressure tolerances, so understanding the system's maximum working pressure is the first step in choosing the right connector. Common Flare Fittings standards include SAE (Society of Automotive Engineers), JIS (Japanese Industrial Standard) and DIN (Deutsches Institut für Normung). The Flare Fittings corresponding to these standards are suitable for different pressure ranges and application scenarios.
SAE standard: Applicable to automobiles and hydraulic systems, with high pressure resistance, widely used in hydraulic systems and environments with high pressure.
JIS standard: Mainly used in the Japanese market, especially in automobiles and industrial equipment, it has reliable sealing performance.
DIN standard: Widely used in the European market, suitable for high-pressure gas, liquid and various industrial equipment, especially suitable for environments requiring high sealing and high strength.
When selecting, make sure that the pressure level of the Flare Fittings can meet the needs of the system to avoid equipment failure or safety hazards caused by excessive pressure on the connector.

Media compatibility: Stainless steel is preferred in corrosive environments

The material of the Flare Fittings needs to be selected according to the connected medium. Whether the liquid or gas medium to be connected is corrosive is an important factor in choosing the right material. If the system uses corrosive media (such as acidic, alkaline solutions, seawater, etc.), it is recommended to give priority to corrosion-resistant materials such as stainless steel or copper alloys.
Stainless steel material: It has extremely strong corrosion resistance and is suitable for connecting pipes with corrosive or high-temperature media.
Copper alloy material: It has excellent corrosion resistance and good thermal conductivity, and is often used to connect pipeline systems with non-corrosive media such as water and gas.
When selecting Flare Fittings, it is necessary to confirm that the selected material can withstand the corrosive substances in the working environment to ensure long-term stable operation.

Size matching: Ensure that the pipe diameter and thread specifications are consistent with the existing system

When selecting Flare Fittings, it is crucial to ensure that its size matches the pipe and thread specifications of the existing system. The outer diameter and inner diameter of the Flare Fittings need to be precisely matched with the size of the pipe, otherwise it may cause problems such as sealing failure, air leakage or liquid leakage.
Pipe diameter matching: Flare Fittings must ensure that they are consistent with the outer diameter of the pipe. Common Flare Fittings are suitable for various standard pipe diameters, such as 1/4 inch, 3/8 inch, 1/2 inch, etc.
Thread specification matching: The thread specifications of the Flare Fittings must match the thread interface of the equipment to ensure a stable connection and good sealing. Common thread specifications include NPT (National Pipe Thread) and BSP (British Standard Pipe).
When selecting, it is necessary to measure the pipe diameter and thread specifications of the existing pipe to ensure that the size of the Flare Fittings is consistent with the pipe and equipment, thereby ensuring the reliability of sealing and connection.

Certification standards: API, ASME and other certified products guarantee reliability

To ensure the quality and safety of Flare Fittings, many suppliers provide products that meet international certifications. These certifications not only mean that the performance of Flare Fittings has reached international standards, but also provide users with higher safety guarantees. Common certification standards include:
API (American Petroleum Institute) certification: Applicable to industries such as oil and gas, ensuring the quality and high-pressure resistance of Flare Fittings.
ASME (American Society of Mechanical Engineers) certification: Ensure that Flare Fittings meet the high standards of mechanical engineering and are suitable for systems with high precision and high strength requirements.
ISO certification: Ensure that the manufacturing process of Flare Fittings meets international quality management system standards and is often used in general industrial applications.
Choosing Flare Fittings products that meet these certification standards can improve the reliability of the system and avoid system failures or safety accidents caused by low-quality accessories.

Selection Criteria Key Considerations Recommendations
Pressure Rating Choose Flare Fittings based on the system's operating pressure. Select SAE, JIS, or DIN standards to ensure pressure capacity meets system requirements.
Medium Compatibility Ensure the material can withstand the corrosive media in the system. For corrosive environments, choose stainless steel; for non-corrosive media, select brass or copper alloys.
Size Matching Ensure the flare fitting's diameter and thread specifications match the existing system. Measure pipe diameter and thread specifications, and select the appropriate flare fittings.
Certification Standards Choose Flare Fittings with international certifications for quality and safety. Opt for Flare Fittings that comply with API, ASME, or ISO standards to ensure reliability.
