What are the different types of JIC fittings?

JIC fittings are widely used in North America. They are a popular hydraulic fluid connector design. This is because they adapt well and seal excellently.

We’ll give an overview of JIC fittings in this blog post, going over their uses, adaptability, and goals.

Know About JIC fitting

A JIC fitting is defined as a flared fitting on a machine with a flared surface that is 37 degrees. Manufacturers typically make them with alloys of nickel, carbon, stainless steel, and brass. JIC fittings are often used in hydraulic connections in most fluid power systems. It features parallel threads with a 37⁰ cone at the fitting end, and it may be attached to a flared pipe or hose fitting. JIC fittings are widely used in fuel transfer and fluid power applications. This is especially true when they involve high pressures, up to 10,000 psi.

How do JIC Hydraulic Fittings Work?

The way JIC Hydraulic Fittings function is by sealing the gaps between their metal parts. Its 37-degree flare angle seals the system well. It is perfect for high pressure. JIC fittings are made up of two parts: the fitting body and the matching nut. The fitting body and nut have 37-degree flare angles on their ends. When you tighten the nuts, they compress the flare against the other nut to form an airtight seal. Tightening also seals against the fitting’s parts.

Features of JIC Hydraulic Fittings

As you know that feature plays an important role in the success of the product. Given below are the list of the various feature of the product are:-

  • Standardized measurements: First, JIC fittings follow standard measurements. This standardization speeds up picking. It ensures you can find a fitting that meets your system’s requirements fast. You’re dealing with a regular setup or a high-pressure application. But, you can rest easy. The dimensions are standard. You can avoid worrying about compatibility. You can avoid a myriad of options by using standards.
  • Material Selection: Brass and stainless steel options are also available. But, JIC Hydraulic Fittings are usually made of premium steel. This makes material selection another crucial consideration. Your particular application will determine the material you select. For instance, stainless steel is a preferable option if you work in an area that is corrosive. The key is that JIC fittings can fit many uses. They don’t compromise on quality because they come in many materials.
  • Pressure Ratings: It’s important to comprehend JIC Hydraulic Fittings’ pressure rating. These fittings work for low- and high-pressure applications. This is because they resist a broad range of pressures.

Various Types of JIC Hydraulic Fittings:

To learn more about the many types of JIC Hydraulic Fittings, take the actions listed below:-

  • Male JIC fittings are often used on hoses or tubes. They have straight threads and 37-degree flare seats.
  • The female versions do not have a flared seat and have straight threads. Conversely, their equivalents are likewise present on ports.

Advantages of JIC Fittings

JIC Hydraulic Fittings have extra advantages. They also have many of the benefits of normal fittings and seals.

  • Universal and affordable : JIC Hydraulic Fittings have been the industry standard for hydraulic fittings. This is due to their wide range of sizes and designs, low price, and ease of use. Now, many US and international companies use JIC Hydraulic Fittings. They fit almost any hose or port. They also convert to imperial or metric measures with ease.
  • High/low temperature : JIC connections function effectively in both hot and cold conditions. JIC fittings metal to metal seals are less affected by temperature than O rings. O rings are usually made of rubber or other elastomeric materials. These can tolerate a narrower range of temperatures.
  • Connectivity: JIC Hydraulic Fittings fit into almost any hydraulic system. They can be detached and rejoined without losing function. These are two more reasons they are industry standards.

Applications of JIC Hydraulic Fittings

Now, JIC Hydraulic Fittings are most often found in plumbing and aerospace.

  • Aerospace industry: NASA, commercial aircraft makers, and private aerospace firms widely use JIC accessories. Commercial aircraft, aviation ground equipment, and aviation fluid systems all employ them.
  • Plumbing industry : JIC fittings are also used in hydraulic systems. They join pipes in flexible networks. Anywhere in the system needs flexibility and adaptability. They can be fastened to hoses as adapters for SAE female fittings.
  • Hydraulic Equipment : They are used in general purpose hydraulic equipment. This equipment includes pumps, cylinders, and valves. They are a good option for many hydraulic systems. This is because they are the same size and compatible.


JIC fittings are versatile hydraulic connectors. They are widely embraced in North America for their adaptability and great sealing. They have standardized sizes, diverse materials, and wide pressure ratings. They work in industries like aerospace, plumbing, and hydraulics. This cements their status as industry standards.
