Hydraulic Connections

Hydraulic fittings connect conductors such as hoses, pipes and tubes in a hydraulic system. Most fittings have a male and female component that join to form a connection. These connections help contain and direct the flow of hydraulic fluid in the conductor while preventing leaks and maintaining pressure.

What are the different types of hydraulic connectors?

Types of hydraulic fittings vary depending on their sizes, configuration, and thread types. The three most common types of hose fittings are O-ring, mated angle and threaded.

What are the most common hydraulic fittings?

The three most common fitting ends and connector types for hydraulic fittings are the O-ring, the mated angle, and the tapered thread connectors. Although these are the most popular choices, several other types are used in different and specialised applications.

How do you connect hydraulic lines?

And the way you connect it you pull a collar. Back. And then you take the male portion put it in and

How do you read hydraulic fittings?

There are six types of threads commonly used on hydraulic tube fittings: UN/UNF. NPT/NPTF. BSPP (BSP, Parallel) ... Four Steps to Thread Identification

1. Step 1 – Determine if the thread is tapered or parallel.
2. Step 2 – Determine the pitch. ...
3. Step 3 – Determine the size. ...
4. Step 4 – Designate the thread.

What is a JIC hydraulic fittings?

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.

What is the difference between JIC and 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.

How do I know if my hydraulic fittings are JIC?

In a word,if the fittings has a 37° flare (sealing surface angle)and straight United National Fine straight Threads (UNF) after inspection. It can be identified be JIC fitting.

What is the difference between JIC and SAE fittings?

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, and 10 share the same thread size.

How does a hydraulic quick coupler work?

Hydraulic quick couplings provide users with the ability to rapidly connect and disconnect hydraulic hoses to machines or other sections of plumbing. Also called quick-connects or quick disconnects, these fittings allow fluid to flow when the male and female sides are locked together.

How do you fix hydraulic pipes?

There are two ways to cut and mend a high-pressure or hydraulic hose. The first way is to use a mender by putting a physical piece inside the hose and crimping it on both ends. The other way to mend a hose is to put two threaded pieces on either side of the splice and put a coupler in the middle.

How do you fix a leaking hydraulic coupler?

First check the male part for dents and scratches to see if it's damaged and needs to be replaced.

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.

How do I know what size hydraulic fittings I need?

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.

How do you read hydraulic hoses?

In the vast majority of common hydraulic hoses, the I.D. measurement is divided into 1/16” increments known as the “dash size.” For example, a hose measuring 3/4” ID will be shown as a “-12” coming from the numerator of the fraction of 3/4″=12/16”. A 1” ID would be 16/16 or a -16, and so on.

What is the difference between JIS and JIC?

Usage difference: JIS hydraulic fttings mainly used in Japanese and Korean heavy equipment such as Komatsu, Kobelco, Hitachi, Kubota etc, often used as hose adaptors. JIC hydraulic fittings mainly used in North America market, also popular in the worldwides.

Is UNF and JIC the same?

Commonly referred to as just JIC fittings these metal to metal sealing type fittings have a 37° flare (sealing surface angle) and straight United National Fine straight Threads (UNF).

What does ORS fitting mean?

ORS-to-ORS steel hydraulic hose adapters are typically used to connect compatible hydraulic hoses to pipe or equipment in high-pressure hydraulic systems. These steel fittings provide good wear resistance, conductivity, and durability. They have an ORS (O-Ring Seal) connection on both ends of the fitting.

What does SAE stand for threads?

Society of Automotive Engineers (SAE) Threads These fittings are commonly used in refrigeration, automative and low presure applications. SAE 45° SAE J512. SAE male has 45° flare which seals against 45° seat in female. Male can also seal against 45° flared tubing with nut and sleeve.

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.
