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", specifically under the sections "Understanding the Numbers" and "Choosing the Right Fitting".

To determine the size of hydraulic fittings you need, you should measure the inside diameter (ID) and outside diameter (OD) of your hoses or tubes, as well as the thread size if applicable. This can be done using a caliper or other measuring tool. This information can be found on https://www.hydraulicsdirect.com/How-..., specifically under the sections "How to Measure Threads" and "Identifying Thread Pitch/Diameter". See full answer »

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. See full answer »

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. See full answer »

To determine your JIC fitting size, measure the outside diameter (OD) of the male thread or the inside diameter (ID) of the female thread using calipers. Then, compare your measurement to a JIC fitting size chart to identify the corresponding size. See full answer »

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. See full answer »

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. See full answer »

To determine if you have JIC (Joint Industry Council) or NPT (National Pipe Taper) fittings, check the thread type and angle. JIC fittings have a 37-degree flare seating surface and use straight threads, while NPT fittings have a tapered thread designed to create a seal by wedging the threads together. See full answer »

JIC fitting stands for Joint Industry Council fitting, which is a type of hydraulic fitting commonly used in high-pressure applications. These fittings feature a 37-degree flare seating surface that provides a reliable, leak-free connection, making them popular in various industries, including automotive and aerospace.

A 3/4/16 thread size refers to a fastener with a nominal diameter of 3/4 inch and 16 threads per inch (TPI). This specification typically follows the Unified National Fine (UNF) thread standard, indicating a finer thread pitch compared to the Unified National Coarse (UNC) standard. See full answer »
