Adjustable AB 45° elbows with JIC threads 

45° female swivel elbow connector body. AB elbow with American JIC threads. In some situations where the use of a standard 90-degree AB elbow° is impossible, we are forced to use another solution - an AB elbow with a 45-degree angle comes to the rescue. These elbows have identical parameters as standard elbow connectors, and the only difference is the 45-degree bending angle. Fittings made of free-cutting steel, zinc-plated. This type of fitting is used to connect hydraulic hoses. AB JIC 45-degree elbows are specialized hydraulic components that allow for a change in fluid flow direction at a 45-degree angle in hydraulic systems. They are equipped with JIC (Joint Industry Council) type threads, ensuring reliable and leak-proof connections in high-pressure systems. JIC threads provide ease of assembly and disassembly, as well as excellent connection tightness. The 45-degree angle allows for flexible design of hydraulic systems, enabling optimal hose routing in confined spaces. AB JIC 45-degree elbows are widely used in various industrial sectors such as power hydraulics, automotive, agriculture, construction, or the maritime industry. They are used in the hydraulic systems of machines and equipment where reliable and leak-proof connections at a 45-degree angle are required. Thanks to them, it is possible to efficiently manage space and minimize stresses in hydraulic hoses. We also offer 45-degree male stud elbows ( designed to be screwed into a body, cylinder, block, or other component ). Adjustable 45° elbow with swivel nut

AB JIC 45° elbows for power hydraulics

AB JIC 45° elbows are hydraulic fittings designed to change the direction of the installation at a 45° angle. They use the JIC standard with a characteristic 37° sealing cone and UNF threads. The AB design combines two different types of ends, making the elbow a practical connecting element in power hydraulic installations.

A 45° angle works well where the hose should be routed more gently than when using a 90° elbow. Proper positioning of the connection helps to adapt the installation path to the machine structure, available space, and the position of other system components.

JIC 45° elbows with 37° sealing cone

The JIC standard is widely used in power hydraulics. The connection utilizes 37° conical surfaces, which are responsible for sealing after the cooperating elements are correctly tightened. UNF threads perform a mechanical function, so when selecting, both the thread size and the compatibility of the sealing surfaces should be verified.

Do not select an elbow based solely on the thread diameter. Dimensionally similar connections may belong to other standards and use a different sealing method.

What does AB design mean?

The AB designation defines the configuration of the fitting's ends. In AB elbows, one side has a swivel nut connection, while the other is finished with an external thread. When replacing an existing element, it is therefore necessary to check not only its size but also the arrangement of the individual connection types.

Proper recognition of the configuration is particularly important when servicing an existing installation. A fitting with an identical angle and thread size, but a different end configuration, may not fit a given system.

Where are AB JIC 45° elbows used?

• in power hydraulic systems,
• in mobile hydraulics,
• in agricultural and construction machinery,
• in industrial machines and equipment,
• in installations using JIC 37° connections,
• during construction, repair, and modernization of hydraulic systems.

Why is it worth using a 45° hydraulic elbow?

The use of an angled fitting allows for changing the connection direction without the need to route the hose directly in the port axis. The 45° variant is particularly useful when the hose should be directed at a gentler angle relative to the connection.

This can facilitate hose routing in a compact machine design and limit the need to force unfavorable hose positioning right at its end. The final choice of angle should always take into account the design of the specific installation.

How to choose an AB JIC 45° elbow?

Before purchasing, the parameters of both sides of the fitting should be precisely determined. In the case of JIC connections, it is particularly important to correctly identify the UNF thread and the 37° cone. If the elbow is to replace an existing element, it is worth comparing its markings and dimensions with the part being removed.

• check the AB connection configuration,
• confirm the JIC standard,
• determine the UNF thread sizes,
• verify the 37° sealing surfaces,
• check if a 45° angle is required,
• compare the technical parameters of the specific variant.

JIC vs ORFS, BSP, and metric connections

JIC must be distinguished from other systems used in hydraulics. The JIC connection uses a 37° cone, while ORFS is based on a face seal with an O-ring. BSP connections and metric systems also have their own thread geometry and sealing surfaces.

For this reason, elements belonging to different standards should not be used interchangeably just because their diameters seem similar. Correct identification of the standard is one of the most important steps in selecting a hydraulic fitting.

JIC 45° or 90° elbow?

A 45° elbow allows for a gentler change in installation direction, while the 90° variant allows for a right-angle connection. The choice should depend on the port position, the hose routing direction, and the amount of available space.

Before installation, it is worth planning the hose path to limit unnecessary stresses and leave access for future servicing.

JIC fittings for hydraulic installations

AB JIC 45° elbows are one of many types of elements that enable building an installation in the JIC standard. Depending on the system design, straight fittings, tees, reducers, and other connection variants may also be needed.

FAQ - AB JIC 45° elbows

What does JIC mean in a hydraulic elbow?

JIC is a connection standard using UNF threads and sealing surfaces made at a 37° angle.

What does AB mean in the elbow designation?

AB defines the end configuration: a swivel nut connection on one side and an external thread on the other.

When to use a JIC 45° elbow?

The 45° variant is useful when a gentler hose direction relative to the connection axis is required than with a 90° elbow.

How to choose the size of a JIC elbow?

You should check the UNF thread sizes of both connections, the AB configuration, and the compatibility of the sealing surfaces with the JIC 37° standard.
