Thumbnail Filmstrip of FJX-04-04 | 1/4" Hose x 1/4" JIC 37° Female Swivel Images
A FJX-04-04 | 1/4" hose x 1/4" JIC 37° female swivel is a type of hydraulic fitting that consists of two parts: a hose fitting with a 1/4" inside diameter and a JIC 37° female swivel fitting with a 1/4" tube size and a nominal thread size of 7/16"-20. The JIC 37° female swivel fitting has a cone-shaped seat that mates with a 37° flare on the male fitting, providing a reliable seal in high-pressure hydraulic applications.

Questions & Answers
Popular Questions
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 calculate the appropriate hydraulic hose size, you need to determine the required inner diameter based on the flow rate and acceptable pressure drop. Utilize the formula or reference charts provided by hose manufacturers that correlate flow rate (in gallons per minute or liters per minute) with hose size to ensure optimal performance and efficiency.
NPT (National Pipe Thread) and JIC (Joint Industry Council) 4 are both types of fittings used in fluid systems, but they differ in design and application. NPT fittings have a tapered thread that seals by wedging the threads together, whereas JIC 4 fittings use a 37-degree flare seating surface to create a metal-to-metal seal, providing a more reliable and reusable connection.

About JIC Fittings
Braided Hose Fittings / JIC 37° Flare / SAE J514
Originally named for the now-defunct Joint Industrial Commission (JIC), this connection is very common in fluid power systems. Both the male and female halves of this connection have 37° seats. The seal takes place by establishing a line of contact between the male flare and the female cone seat. The threads hold the connection mechanically.
