JIC fittings are manufactured in accordance with SAE J514 and ISO 8434-2 standards, a complete set of JIC fittings consists of sleeve, nut, and body and the body is machined with a 37 degree flared seating surface. In the market, this is known as flared accessories. This accessory is designed to be used in many different sectors and especially in the high-pressure industry.

What is the pressure rating of JIC fittings?
In selecting JIC fittings, you must know their pressure rating. Nominal pressure is a specification parameter and is numerically equal to the maximum working pressure of the system.
According to DIN3859-3 (ISO19879), the maximum working pressure must meet 4 times the static safety parameters and 1.33 times the dynamic safety factor, that is, through the blast test to detect the divided burst pressure By 4, the maximum pulse pressure divided by 1.33, take the lower values and define it as the maximum working pressures.
How to select JIC fittings according the working pressure?
When selecting JIC fittings, the maximum working pressure of each joint is at least equal to the set maximum working pressure of the entire hydraulic system in one working state. Not only consider the outlet pressure of the pump but also consider the starting pressure of the relief valve.
Therefore, in the design of complex hydraulic pipes, it is better to achieve the practice pressure by measuring the site. The system working pressure has been set, then to verify the maximum working pressure of each pipe adapter.
The maximum working pressure of JIC adapter fittings can vary depending on the sealing method or temperature: for the same pipe joints, the selected elastic seal will obtain a higher working pressure than the rigid seal.
