Popular Questions
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.
JIC stands for "Joint Industry Council," and it refers to a type of thread standard commonly used in hydraulic fittings. JIC threads have a 37-degree flare seating surface, which provides a metal-to-metal seal for high-pressure applications. This standard is widely used due to its reliability and compatibility with various hydraulic systems.
ORB (O-Ring Boss) and JIC (Joint Industry Council) fittings are both types of hydraulic fittings but differ in their sealing methods and applications. ORB fittings use an O-ring to create a leak-proof seal, making them ideal for high-pressure applications. JIC fittings, on the other hand, have a 37-degree flare seating surface and rely on metal-to-metal contact for the seal, which allows them to be used in a wide range of applications due to their versatility and ability to handle moderate pressures.
JIC fittings are sized based on the outer diameter of the tubing they are intended to connect, typically measured in inches. The sizing is denoted by a dash number, which represents the tube size in sixteenths of an inch. For example, a -04 JIC fitting is designed for tubing with an outer diameter of 1/4 inch.
A JIC (Joint Industry Council) fitting will not fit directly into an NPT (National Pipe Tapered) fitting because they have different thread types and sealing methods. JIC fittings use a 37-degree flare for sealing, while NPT fittings rely on tapered threads to create a seal. To connect these two systems, an adapter is typically required.
A #4 JIC fitting refers to a specific size in the Joint Industry Council (JIC) fitting standard, which is commonly used for hydraulic systems. The #4 size corresponds to a 7/16-20 UNF (Unified National Fine) thread, and it is designed to fit a tube with an outer diameter of 1/4 inch. JIC fittings are known for their 37-degree flare seating surface, providing a reliable, leak-proof connection.
The 1/4 JIC refers to a type of fitting thread used in hydraulic systems, specifically following the Joint Industry Council (JIC) standards. The 1/4" JIC fitting typically has a 7/16-20 UNF (Unified National Fine) thread. This type of fitting is known for its 37-degree flare seating surface, which provides a reliable, leak-proof seal.
