What is the difference between jic and jis fittings

Japanese Industrial Standards (JIS) Threads. JIS Threads. JIS. Japanese Industrial Standards.

What is a JIS hydraulic fitting?

JIS fittings are typically used as hose adapters on equipment designed and/or manufactured in Japan and Korea. Parker's JIS adapters are designed with 30° flare and 60° cone connections and typically incorporate BSP threads.

What is a JIC fitting used for?

JIC fittings, defined by the SAE J514 and MIL-DTL-18866 standards, are a type of flare fitting machined with a 37-degree flare seating surface. JIC (Joint Industry Council) fittings are widely used in fuel delivery and fluid power applications, especially where high pressure (up to 10,000 psi) is involved.

How do I know if my hydraulic fittings are JIC?

Four steps to know if your fittings are JIC:

Identify if the thread is parallel or tapered. NPT/NPTF and BSPT are tapered threads while UN/UNF and BSPP are parallel.
Determine the flare angle by using a calipers.
Determine the thread diameter. ...
4.Identifying the thread by gauge.

Can you mix JIC and an fittings?

JIC Steps In The majority of the hydraulic population agrees, the JIC (or SAE) 37 degree fittings are generally interchangeable with AN fittings.

Do JIC fittings need sealant?

Even though JIC threads seal with a metal-to-metal connection, no thread sealant is required to achieve a leak free connection.

Is JIS the same as BSP?

JIS tapered thread connections are interchangeable with BSPT connections. connections are interchangeable with BSPP connections.

How can you tell the difference between JIC and SAE fittings?

The most common flare fitting standards in use today are the 45° SAE style, and the 37° AN style, also used with the JIC system. The AN / JIC style generally has a higher pressure rating for a given size tubing. SAE and AN/JIC fittings are completely incompatible due to the different flare angle.

What is a JIS thread?

Japanese Threads Most other Japanese heavy equipment manufacturers use fittings with a 30° seat and BSPP (British Standard Pipe Parallel) threads. This combination is referred to as JIS (Japanese Industrial Standard).

Why is it called JIC fitting?

What does JIC stand for? JIC stands for the Joint Industries Council, which first standardized industrial use fittings. These compression couplings have a 37° flared seat on the male and female threaded connections.

Is JIC better than NPT?

JIC fittings come with a 37O flare angle, while the NPT fittings rely on just their tapered threads for sealing. As a result, JIC fittings offer better sealing capabilities and can withstand higher working pressures.

Do JIC fittings need O rings?

Most commonly used as hydraulic fittings in the fluid power industry, JIC (Joint Industry Council) fittings are a type of flare fitting machined with straight threads using a 37° flare seating surface. This is used to form the seal of the fitting instead of an o-ring or tapered threads.

How do you tighten a JIC fitting?

3 Steps to Improved Sealing of JIC Connections:

Tighten the nut by hand until it bottoms the seats.
Using a marker, draw a line lengthwise on the nut and extend it onto the adapter.
Using a wrench, rotate the nut to tighten. Turn the nut the amount shown on the chart.

What size thread is JIC?

Inch size	Dash size	Female thread O.D (in)
¹⁄₂	-8	¹¹⁄₁₆
⁵⁄₈	-10	¹³⁄₁₆
³⁄₄	-12	1
⁷⁄₈	-14	1 ¹⁄₈

How does JIC seal?

However tifco now has a way to save your damaged jic fittings usa made flare tight seals flare tight

Is JIC 37 or 45?

The JIC female has straight threads and a 37° flare seat. The Seal is made on the 37° flare seat. The SAE 45° flare male will mate with an SAE 45° flare female only. The SAE male has straight threads and a 45° flare seat.

Should you use Teflon tape on hydraulic fittings?

No. Teflon tape is for thread sealing. Hydraulic fittings are not sealed in the thread. They are sealed by O-ring or ferrule compression, neither of which requires teflon tape.

Will a 45 degree flare work on a 37 degree fitting?

JIC 37 degree flare union fittings is in most hydraulic systems in high pressure application such hydraulic excavator, loader and tractor etc. SAE 45 degree flare fittings is used in low to medium pressure applications such as military and aerospace equipment. they doesn't interchangeable into each other.

How do I stop my JIC fittings from leaking?

But leaking flare joints can be eliminated by installing a conical washer between the JIC nose and flare. One type of flare seal, manufactured by Flaretite, consists of a stainless steel stamping, with concentric ribs that contain pre-applied sealant.

How tight should hydraulic fittings be?

Once aligned, tighten the nut until it is "firm" against the washer and o-ring, with the nut becoming snug with a feel of metal-on-metal in less than one revolution. Over-tightening causes as many leaks as under-tightening.
