The numbers on hydraulic fittings refer to the size and type of the fittings. They can indicate the fitting's thread size, pitch, and compatibility with other components. This information was sourced from "Hydraulic Hose Fittings Guide: How to Find the Right One" on the Hydraulics Direct website (https://www.hydraulicsdirect.com/Unde...), specifically under the sections "Understanding the Numbers" and "Choosing the Right Fitting".
The standard for hydraulic fittings is typically governed by organizations such as the International Organization for Standardization (ISO) and the Society of Automotive Engineers (SAE). Common standards include ISO 8434 for metallic tube connections and SAE J516 for hydraulic hose fittings, which ensure compatibility, reliability, and safety in hydraulic systems.
JIC (Joint Industry Council) and JIS (Japanese Industrial Standards) refer to different sets of standards: JIC is primarily used in North America for hydraulic fittings and defines specifications for a 37-degree flare fitting, while JIS is a Japanese standard that covers a wide range of industrial components, including a 30-degree flare fitting. The key difference lies in their regional origins and specific design specifications.
To identify JIC fittings, first measure the outer diameter of the male thread or the inner diameter of the female thread using a caliper. Then, compare these measurements to a JIC thread size chart to determine the correct size, ensuring the fitting has a 37-degree flare angle, characteristic of JIC fittings.
To identify types of hydraulic fittings, you can look at the thread type (such as NPT, BSP, or metric), the sealing method (like O-ring, metal-to-metal, or tapered), and the fitting shape (such as elbow, tee, or straight). Additionally, checking the manufacturer's specifications and using a thread gauge can help ensure accurate identification.
The JIC (Joint Industry Council) fitting is equivalent to the AN (Army-Navy) fitting in terms of thread size and pitch, but they are not identical. Both types use a 37-degree flare to create a metal-to-metal seal, making them compatible for many applications, though AN fittings are typically made to stricter military specifications.
To determine the fitting size for a 3/8" hose, you typically need a fitting that matches the hose's inner diameter, which is 3/8". Depending on the type of fitting (e.g., barbed, compression, threaded), ensure it is compatible with the hose material and application requirements. For instance, a 3/8" NPT (National Pipe Thread) fitting would have threads designed to fit a 3/8" hose.
JIC stands for Joint Industry Council, which refers to a type of fitting used in hydraulic systems. JIC fittings are known for their 37-degree flare seating surface, providing a reliable, leak-proof connection that is commonly used in high-pressure applications. They are widely utilized due to their versatility and compatibility with various piping systems.
