HYDRAULIC HOSE FITTINGS
what is hydraulic fitting
Hydraulic fittings are used in hydraulic systems to connect hydraulic hose to other hydraulic components such as adapters, valves, pumps, and cylinders.
It has two ends, one of which is crimped onto the end of the hydraulic hose by a ferrule and the other of which is attached to the hydraulic component via a male thread, female thread, or flange connection. Because of the two-way connection, the hydraulic fitting could be a weak point for leaks or service life. As a result, selecting the suitable one is crucial to ensuring the quality and safety of the hydraulic system.
Given the wide range of hydraulic fittings available, using our taxonomy might help you find the best one for your needs. This taxonomy derives from the Eaton-Winner classification system, which is widely utilized by Chinese suppliers. You will get the specific fitting code to place your order.
The category of hydraulic fitting
Swaged Metric Hose Fittings
swaged metric hose fittings have swaged nozzle on the tail part, the connection port has metric thread type or flange which comform to metric standards in Europe market.
Swaged British Hose Fittings
Swaged British hose Fittings have swaged type nozzle on the tail part, and the thread type comforms to British Standard Pipe which is entensively accpeted in the British market.
Swaged American Hose Fittings
Swaged American Hose fittings refer to the fittings with connection port whose thread type comform to several standards in the US. JIC, NPT, ORFS, SAE etc are covered.
Swaged Japanese Hose Fittings
Swaged Japanese hose fitting are frequently seen on the Janpan made construction engineering machine, Janpan has it’s own thread standard because of it’s advanced manufacture induststy in the past
Swaged Staple-lock Male Fittings
Swaged staple-lok male fittings are gennerally utilized in mine’s roadway to support the tunnel for anti collapse, they bear static pressure in application and easy to fix with quick lock.
Swaged Banjo Fittings
Swaged banjo fittings have a shape like a banjo, they are often used on the small room on the machiney, it is easy to change the fulid direction, an hollow bolt with a hole has thread
Swaged Double Connector
Swaged double connector has indentical to side, they are insered into two hydraulic hose end to connect them together, specific ferrule mated with them are required to crimpe
Interlock Fittings
Interlock fittings are specially designed to be crimped on the tail part when connecting with a hydraulic hose, it has two section on the nozzle, one is for locking and the other is for sealing
Reusable Hose Fitting
Reusable hose fitting seems to be an out-of-date fittings, but it has two outstanding features, can be reusable and can be fixed and unstalled with wrench on the field. so for the sake of convinience,
The classification of hydraulic fitting
In the first level, we classified our hydraulic fittings into three types, with the tail part serving as the foundation.
Swaged Fittings
Interlock Fittings
The difference is that the connection part inserted the hydraulic hose is divided into two section in function; one is for locking, and the other is for sealing.
Reusable Fitting
this kind of hydraulic fitting is not crimped via crimping machine when make hydraulic assembles, the ferrule mated has thread, it can be fixed with wrench, and can be reusable when re-fixed on another hydraulic system.
Even though they have been employed with a crimping machine, swaged fittings are more common and more dependable in industrial applications than interlock fittings and reusable fittings. They are separated into various sections based on various thread types from various regions, such as Britain, Europe, America, and Japan, as well as some special highlighted goods, such as staple-lock fittings, banjo fittings, and double connector.
Thread type
In mechanical industry, thread type is divided into two types in function: one is for connection, and the other is for convey power; the existence of the fittings in the hydraulic assemble is for connection;
Different countries or areas have their own standard to shape the thread specification owing to their industrial development background, the main dimension of the thread covers thread form, thread angle, and the distance of adjacent thread or Threads per Inch.
Here, we list the thread types we offered which covers almost all types in the main market:
Metric thread- these thread type dominate the mainland of Europe, which has some intersection with German DIN standard;
BSP- these thread type are popular in British or some Commonwealth countries;
NPSM, NPT, ORFS, JIC, SAE are some American standards which are popular in North America;
JIS- JIS is a Japanese thread type standard;

The seal type of hydraulic fitting
Tapered Thread Seal
Cone Seat VS Chamfer Seat ; Multiseal VS Chamfer Seat
Bite Type Tube Seal
The material of hydraulic fitting
The material of hydraulic fittings includes plastic, brass, aluminum, carbon steel, and stainless steel; when considering the cost and properties of the material, galvanized carbon steel hydraulic fittings predominate in our dealings with clients; however, stainless steel hydraulic fittings are sometimes required for certain applications, such as anti-corrosion requirements.
