What are the different types of hydraulic fittings?
What are the different types of hydraulic fittings?
Why are There so Many Different Types of Hydraulic Fittings? While there might be hundreds if not thousands of hydraulic fittings and connectors, they all boil down to three basic types. These three types are either metal seal, soft seal, or tapered thread connectors.
What does JIC mean in hydraulic fittings?
Joint Industry Council
JIC (or Joint Industry Council) fittings, defined by SAE J514, are compression fittings machined with a 37 degree flare seating surface and parallel threads. They are commonly manufactured in nickel alloys, brass, carbon & stainless steel. JIC Fitting hydraulic connections are common in most fluid power systems.
How do I know what size hydraulic fittings I need?
How to Measure Your Hydraulic Fitting
- First you should determine the length of a hydraulic fitting by laying it on a table and then stretching your measuring tape across the top of it.
- Next, determine the outside diameter of the fitting by using your ID/OD calipers.
Are hydraulic fittings the same as an fittings?
The majority of the hydraulic population agrees, the JIC (or SAE) 37 degree fittings are generally interchangeable with AN fittings.
What is the difference between JIC and JIS fittings?
Sealing difference: JIS adapter fittings has 30 degree flare tube connector, but thread has BSPP and Metric (also called Komatsu style fittings). JIC adapter fittings is 37 degree flare tube connectors, with UNF thread.
What are the three basic types of threads?
Three are parallel (UN/UNF, BSPP, metric parallel) and three are tapered (NPT/NPTF, BSPT, metric tapered). Three are pipe threads (NPT/NPTF, BSPT, BSPP) and three are not (UN/UNF, metric parallel, metric tapered).
Should you use thread sealant on hydraulic fittings?
You don’t need or should use any teflon tape or pipe dope on hydraulic fittings. Neither are designed for those kinds of pressures and using them could create a less then perfect mating between connection surfaces causing more harm than good.
What does SAE stand for in hydraulics?
Abbreviations
| NPTF | National Pipe Tapered Fuel |
|---|---|
| SAE | Society of Automotive Engineers |
| JIC | Joint Industrial Council |
| NFPA | National Fluid Power Association |
| BSP | British Standard Pipe |
What size is a number 12 hydraulic fitting?
JIC 37° Flare (SAE J514)
| Inch size | Dash size | Female thread O.D (in) |
|---|---|---|
| 3⁄4 | -12 | 0.98 |
| 7⁄8 | -14 | 1.10 |
| 1 | -16 | 1.23 |
| 1 1⁄4 | -20 | 1.54 |
How do you determine your fitting size?
You can always identify AN fittings based on the male thread size (outside diameter). These sizes are constant regardless of brand, hose type, or fitting configuration. If your fitting has a convex 37 degree flare at the end, the threads will tell you the AN size (and vice-versa).
Are hydraulic fittings NPT?
JIC hydraulic fittings is used in high pressure system, NPT fittings is used in low-pressure system. NPT pipe threads have always been popular, as leaks can be fixed by simply tightening the fitting. NPT is often used to connect port, hydraulic adapter has a combination from JIC to NPT end fittings.
What does JIS stand for in fittings?
JIS stands for Japanese Industrial Standard and is used for threads on hydraulic fittings.
Which is the best hydraulics company in New Zealand?

How are hydraulic hose fittings used for hydraulic fluid?
Screw-On Hose Fittings for Hydraulic Fluid These two-piece fittings screw directly onto the hose without the need for a separate adapter. When assembled, the fitting compresses against the hose, forming a strong seal. Also known as reusable fittings, they can be unscrewed from the hose end and used on a new hose.
How are compression fittings used for hydraulic power?
They withstand about twice as much pressure as sleeves for standard compression fittings, so they’re good for hydraulic power applications. A tube adapter sits flush against the flat face of the fitting so you can slide the steel tubing and fitting sideways to disconnect in cramped spaces.
What are the different types of hydraulic pipe fittings?
These standards include straight thread series as well as tapered series for a wide variety of applications requiring pressure-tight sealing or rigidity and, sometimes, both together. Threaded pipes offer an effective seal on pipes that are used to transport hydraulic fluid, steam, gases, or liquids.
