What Is a Hydraulic Hose Fitting?
A hydraulic hose fitting is a component that connects hydraulic hoses and piping.
They are used to connect different types and sizes of hydraulic hoses and piping. Hydraulic hose fittings are relatively easy to detach and reattach, which is useful when hoses or peripheral equipment are damaged. New hoses or piping materials can be connected quickly.
The adapters also allow for flexible adjustment of hose orientation and position. However, the connection point of the adapter is where leakage of hydraulic fluid may occur.
If not properly installed and tightened, leaks can often occur. This can affect the performance and safety of the system, so care must be taken.
Applications for Hydraulic Hose Fitting
Hydraulic hose fittings are widely used in various industries. The following are applications for hydraulic hose fittings:
1. Construction Machinery
In construction machinery, hydraulics are very important. Heavy equipment and cranes use hydraulics to control large loads, and excavators utilize hydraulics to excavate the ground.
These machines may work with different attachments and hydraulic hose fittings make it easy to connect these attachments.
2. Industrial Machinery
In industrial machinery, hydraulic pressure is used to control mechanical pressure. Presses use hydraulics to generate force to form metal, and robot arms use hydraulics to achieve complex motions. These hydraulic pipes are often connected via hydraulic hose fittings.
3. Agricultural Machinery
Hydraulic systems are also used in agricultural machinery to control the motion of tractors and combines. Tractor blades and excavators are operated by hydraulic pressure and are utilized to till the land in the fields. Hydraulic hose fittings are a component that connects different attachments and equipment and assists in the various functions of agricultural machinery.
Principle of Hydraulic Hose Fitting
Hydraulic hose fittings are components used to connect different types and sizes of hydraulic hoses and piping. They serve to transmit power in hydraulic systems.
Adapters are designed to conform to standards such as NPT and JIC. Since most hydraulic hoses are made overseas, hydraulic hose adapters are often designed to meet those standards. By selecting the appropriate adapter, different connection ports can be easily connected.
They are generally attached to the hose or piping by a threaded part or other means. The connecting part is inserted into the hose or pipe connection and secured by properly tightening it. In this process, a proper seal is formed between the connecting surfaces to prevent leakage of hydraulic fluid.
Hydraulic hose fittings are made of durable materials. Materials with high strength and durability are often used, with steel and stainless steel being the most common materials. Adapters used in harsh environments, such as industrial machinery and heavy equipment, in particular, require high durability.
Types of Hydraulic Hose Fitting
There are various types of hydraulic hose fittings, designed to meet different standards and applications. The following are types of hydraulic hose fittings:
1. NPT Thread Adapter
The NPT thread is a standard used primarily in the United States. It has a conical internal thread and is designed to fit closely with the external thread. It is commonly used in liquid and gas handling applications.
2. Unified Thread Adapter
Unified threads are a widely used international standard. There are two types of Unified Threads: Thin Unified Threads (UNF threads) and Coarse Unified Threads (UNC threads), each selected for a specific application. These threads have straight connections and may require additional sealing material to form a seal.
3. DIN Metric Thread Adapter
DIN metric threads are a metric thread standard designed according to the German DIN standard. It includes different variants of metric threads, represented in the form, for example, M10x1.5. It is widely used, especially in Europe, for assembling machinery and equipment.
