Unveiling the secrets of ‘inverted flare fitting’: your ultimate guide
What To Know
- An inverted flare fitting, also known as a JIC flare, is a type of tube fitting that creates a leak-proof seal by flaring the end of the tube outward into a cone shape and then mating it with a matching cone-shaped seat.
- The inverted flare design provides a secure and reliable connection for hydraulic and pneumatic systems, making it a popular choice in various industries.
- Inverted flare fittings create a seal by flaring the tube outward, while compression fittings use a ferrule to compress the tube against the fitting body.

Advantages of Inverted Flare Fittings
- High Pressure and Temperature Tolerance: Inverted flare fittings are capable of withstanding extreme pressure and temperature conditions, making them suitable for demanding applications in hydraulic and pneumatic systems.
- Leak-Proof Seal: The cone-shaped design and the use of a sealing washer ensure a leak-proof connection, even under high pressure and vibration.
- Ease of Assembly and Disassembly: Inverted flare fittings are relatively easy to assemble and disassemble, making them convenient to use and maintain.
- Compact Size: The compact design of inverted flare fittings allows for space-saving installations, especially in confined areas.
Components of Inverted Flare Fittings
An inverted flare fitting typically consists of three main components:
- Tube: The tube is the component that is flared to create the seal.
- Fitting Body: The fitting body contains the matching cone-shaped seat and a port for connecting to the system.
- Nut: The nut is used to tighten the tube into the fitting body and secure the connection.
Types of Inverted Flare Fittings
Inverted flare fittings are available in various types, depending on the size and shape of the tube and the application requirements. Common types include:
- 37° Flare: This is the most common type of inverted flare fitting, with a 37° cone angle.
- 45° Flare: This type has a 45° cone angle and is often used in high-pressure applications.
- Straight Flare: Straight flare fittings have a 0° cone angle and are used for low-pressure applications.
- Bulkhead Flare: These fittings are designed to pass through a bulkhead or panel and provide a leak-proof connection from one side.
Applications of Inverted Flare Fittings
Inverted flare fittings are widely used in various industries, including:
- Hydraulic systems
- Pneumatic systems
- Automotive industry
- Aerospace industry
- Medical equipment
- Instrumentation
Installation of Inverted Flare Fittings
Proper installation is crucial to ensure the integrity and performance of inverted flare fittings. Here are the general steps involved:
- Prepare the tube by cutting it to the appropriate length and deburring the edges.
- Flare the end of the tube using a flaring tool.
- Apply a sealing washer to the fitting body.
- Insert the flared tube into the fitting body and tighten the nut.
Troubleshooting Inverted Flare Fittings
If an inverted flare fitting is not sealing properly or is leaking, it is important to troubleshoot the issue promptly. Common causes include:
- Improper flaring of the tube
- Damaged sealing washer
- Overtightening the nut
- Contamination or debris in the connection
- Incompatible tube and fitting materials
Inverted Flare Fittings vs. Other Tube Fittings
Inverted flare fittings offer several advantages over other tube fittings, including:
- Higher pressure and temperature tolerance
- More secure and reliable seal
- Compact design
- Ease of assembly and disassembly
However, inverted flare fittings can be more expensive than other types of tube fittings and may require specialized tools for installation.
The Future of Inverted Flare Fittings
Inverted flare fittings continue to be a popular choice for demanding applications due to their reliability and performance. Ongoing advancements in materials and manufacturing techniques are expected to further improve the capabilities and efficiency of inverted flare fittings in the future.
Wrapping Up
Inverted flare fittings are indispensable components in hydraulic and pneumatic systems, providing leak-proof and reliable connections. Understanding their design, advantages, and applications is essential for engineers and technicians working with these systems. By following proper installation and maintenance procedures, inverted flare fittings can ensure the safe and efficient operation of hydraulic and pneumatic equipment.
