What size is a 5'8 flare nut?

SAE 45º INVERTED FLARE – SAE J512

MALE THREAD OD & PITCH	DASH SIZE	TUBE SIZE
7/16 – 24	-07	1/4
1/2 – 20	-08	5/16
5/8 – 18	-10	3/8
11/16 – 18	-11	7/16

.

Furthermore, how do you measure a flare nut?

1) With a caliper, measure the thread diameter at the widest point across the threads (See image below). Outside diameter (O.D.) of male threads. Inside diameter (I.D.) of female threads.

what size is SAE 6? JIC 37° Flare (SAE J514)

Inch size	Dash size	Thread Size
3⁄8	-6	9⁄16 - 18
1⁄2	-8	3⁄4 - 16
5⁄8	-10	7⁄8 - 14
3⁄4	-12	1 1⁄16 - 12

Correspondingly, is JIC the same as SAE?

JIC fittings are dimensionally identical to AN (Army-Navy) fittings, but are produced to less exacting tolerances and are generally less costly. SAE 45-degree flare fittings are similar in appearance, but are not interchangeable, though dash sizes 2, 3, 4, 5, 8, 10, 14, and 16 share the same thread size.

What is a flare fitting used for?

Flare fittings are a type of compression fitting used with metal tubing, usually soft steel, ductile (soft) copper and aluminum, though other materials are also used. Tube flaring is considered to be a type of forging operation, and is usually a cold working procedure.

Related Question Answers

How do you determine your fitting size?

Measure the Outside Diameter (OD) of your pipe or pipe fitting:

1. Wrap a string around the pipe.
2. Mark the point where the string touches together.
3. Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
4. Divide the circumference by 3.14159.

How do I know my JIC size?

Subject: RE: How can you tell what size of JIC hyd fittings you have? The tube fitting size number is the number of 1/16" of the tube or fitting. That is a number 4 is 4*1/16 or 4/16 which is 1/4" and so forth, a number 8 is 1/2" a 16 is one inch.

What is an inverted flare?

Inverted Flare Hydraulic Tube Fittings Recommended or use in hydraulic brake, power steering, fuel lines and transmission cooler lines. Inverted flare fittings are inexpensive and reusable. Inverted flare provides excellent vibration resistance. Seats and threads are internal and protected.

How Do You Measure O ring fittings?

O-rings are measured in millimeters.

1. Place the O-ring on a clean, flat, level surface.
2. Determine the inside diameter.
3. To measure the outside diameter, use a ruler or calipers to measure from one outer corner of the O-ring to the other outer corner.
4. Measure cross section.

Do you use Teflon tape on flared gas fittings?

Do not use Teflon ® tape or pipe sealant on any flare ends because you will not obtain a leak-free seal. Keep flare end of fitting free of grease, oil and thread sealant. Use a wrench only on the hex surfaces of the fittings. tighten more if a leak is detected.

What is 37 degree flare used for?

Defined by MIL-F-18866 and SAE J514 standards, these flare fittings have been machined to have a 37° flare seating surface. These fittings are most commonly used in fluid power and fuel delivery applications, especially those using high pressure.

What size is #6 JIC fitting?

MALE THREAD OD & PITCH	DASH SIZE	FEMALE THREAD ID
inch – TPI	mm
5/16 – 24 UNF	-05	6,9
3/8 – 24 UNF	-06	8,5
7/16 – 20 UNF	-07	9,9

What does JIC mean?

Just In Case

What is SAE thread sizes?

Fasteners: SAE vs. For instance, a ¼” bolt comes in either ¼-20, which is “SAE standard coarse," or ¼-24, which is “SAE standard fine." The -20 and -24 represents how many THREADS PER INCH (thread pitch) are present on the fastener. The larger the number, the more threads there are per inch, thus the finer the thread.

How do you tighten a JIC fitting?

Flats Method Tighten the nut lightly with a wrench (approximately 30 in.lb.), clamping the tube flare between the fitting nose and the sleeve. This is considered the Wrench Resistance (WR) position. Starting from this position, tighten the nut further by the number of flats from the Torque Chart.

What is a SAE fitting?

SAE O-ring (O-Ring Boss) are straight thread fittings that seal using a O-ring between the thread and the wrench flats of the fitting. The O-ring seals against the machined seat on the female port. This makes it easier to strip threads or crack or distort fitting components, which prevents proper sealing.

What is an fitting mean?

The AN thread is a particular type of fitting used to connect flexible hoses and rigid metal tubing that carry fluid. It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army and Navy, hence AN.

What means SAE?

SAE stands for the Society of Automotive Engineers. The SAE was founded in 1905 by Andrew Ricker and Henry Ford. At the outset, its sole aim was to provide an umbrella organization for the scattered automotive engineers who usually worked alone in various parts of the country.

What is the difference between SAE and NPT?

O-Ring Boss: The threads of the SAE straight thread O-Ring Boss (ORB) and the straight thread 37° JIC Flare are the same threads. The difference is the way each thread seals. NPT Pipe Threads: NPT pipe threads are your traditional tapered thread fittings and have been used for 100 years.

What does SAE 8 mean?

The number commonly used for hydraulic hoses, tubes and fittings is the number of 16th of an inch. So an 8 is 8/16 or 1/2". And I would guess that SAE means it has O-ring type ports.

What is a dash size?

Simply put, a dash size refers to a I.D. of a hydraulic hose or fitting in 1/16" increments. For example, -6 hose would indicate a hose with I.D. of 6/16" - or 3/8". Hoses are measured by inside diameter, unlike tubes which are measured by outside diameter.

Is SAE coarse or fine thread?

USS are coarse threads, while SAE are fine threads.

What are NPT ports?

National Pipe Thread (NPT) ports, AN Ports and port adapter fittings: Over the years, in low-pressure hydraulics, NPT has been a popular thread for ports and adapter fittings. When NPT ports are used in a fuel system with AN line, an adapter fitting to convert from NPT to AN is required.

What is an SAE thread?

SAE Thread Type – Straight Thread O-Ring Boss This is a highly reliable and reusable thread type. While some thread types require the threads of the male and female end to crush together to form a seal, the O-Ring on this thread type prevents that.
