What is the sealing principle of JIC 37°cone hydraulic hose fittings?

JIC 37° cone hydraulic hose fittings are common connecting components in hydraulic systems, and their sealing principle is crucial for ensuring efficient system operation and preventing liquid or gas leakage. The sealing principle of these fittings is based on metal-to-metal sealing technology, which offers outstanding reliability and durability.

Firstly, let's delve into the sealing principle of JIC 37° cone hydraulic hose fittings. When two JIC 37° cone fittings are interconnected, their end faces form a complete sealing interface. This sealing interface relies on tight contact between the two metal surfaces, rather than depending on O-rings or other sealing materials. This design advantageously provides higher pressure resistance and longer service life due to the metal-to-metal sealing method.

During the connection process, when two fittings are tightened against each other, a high-pressure area is formed. This high pressure induces plastic deformation of the microscopic irregularities on the metal surfaces, effectively filling and sealing potential gaps. This metal-to-metal sealing method can maintain stable sealing performance under high-pressure and high-temperature conditions, ensuring the safety and reliable operation of hydraulic systems.

While metal-to-metal sealing is the primary sealing method of JIC 37° cone hydraulic hose fittings, they typically also incorporate O-rings or groove seals as additional protective layers. These sealing materials are usually installed at the ends of the fittings and provide additional sealing protection to prevent liquid or gas leakage. This dual-sealing design enhances system safety and stability, particularly in high-pressure hydraulic systems.

The sealing principle of JIC 37° cone hydraulic hose fittings relies on tight contact between metal surfaces. This sealing method offers exceptional reliability and durability and is widely applied in hydraulic systems. By ensuring the sealing performance of the system, these fittings contribute to improving system efficiency, reducing maintenance costs, and ensuring the safe operation of systems. Therefore, understanding the sealing principle of JIC 37° flare hydraulic hose fittings is crucial when designing and selecting hydraulic systems.
