JIC Fittings

JIC stands for Joint Industry Council and are suitable to apply in fluid power system where the power is transmitted and controlled through a fluid under pressure and it is also applicable for general application where the fluid is conveyed under high pressure.

​Fitting sizes are designed to correspond with tubing outer diameter (OD) for various types of tube ends. JIC fitting is used to connect tube in metric and inches size with sleeve and nut upon installation. It is used to install with the assembly of hoses.

What are JIC Fittings

​1. What are JIC fittings?

​
JIC fittings are made in accordance to SAE J514 and ISO 8434-2 standard​s. ​ A complete set of JIC fittings consist of sleeve, nut and body and the body is machined with a 37-degree flared seating surface. This is known as flared fittings in the market. This fitting is designed to use in many different sector and especially in the high pressure industry.

2. What is 37-degree flared used for?

JIC Swivel ( M x F )
JIC Swivel ( M x F )
The JIC body without sleeve and nut is commonly used as a hose adapter for connection to a female swivel end on a hose assembly installation. The nut and body are universal parts that can apply to either metric or inches size tubing while the sleeve is the only part to change corresponding to metric and inches tubes outer diameter.
3. What is the difference between ​​JIC and NPT?
​

JIC and NPT thread are two different thread options in system installation. JIC comes with a 37-degree flared that attaches to either a hose fitting or a flared tube.

4. How JIC fittings seal affects temperature rating?
​
JIC Fittings are available in stainless steel SS316, carbon steel and brass material. Surface contamination is removed and the fitting surface protection is critical and important to enhance corrosion-resistance. Each material works under different temperature rating as below:

Seal material is one of the important factors that affects the overall system temperature rating. NBR O-ring seal material is the default material provided.

5. How do I know my JIC fitting size? 

Both male and female halves of JIC fittings come with 37-degree seats. The connection sealing takes in place when the line of the male flare and female cone seat is attached to each other. JIC fittings size are available in different type of reading. Dash size number is commonly use in the United States to make ordering components easier. It is expressed as the numerator of a fraction where the denominator is always 16. For example, a -08 size or connector is 8/16” or 1/2".

While metric size does not use dash numbers. Thread pitch gauge is used to measure the number of threads per inch or the distance between threads in metric connections. Position the gauge on the threads until the fit is snug. For example M16 x 2.0 equal to 16 mm thread OD with 2.0mm between each thread.
6. How do you tighten a JIC fitting?

There are 4 simple steps to install JIC fittings. 

Step 1: Check on possible contamination or damage on fitting surface and sealing surface. Cut the tube according to the length required and flare the tube head to a 37-degree before installation.
  
Step 2: Apply lubricant such as hydraulic fluid onto the threads and the whole surface of the flare.

Step 3: Insert the nut and sleeve onto the tube end connection. Align components for hand tightening and turn the flare nut until sealing surface is fully contacted. 

Step 4: Check the tighten torque value and ensure the sealing is connected as per standard requirement.

The fittings and tubing connection shall be carried out without external loads. Over tightening may causes deformation of 37-degree flared of the male thread end connection. Excessive deformation of the flare will cause in loss of clamping force and hence sealing loss.
