Weld-on fittings - AS type welding connection
Threaded connectors designed for welding on one side. Our offer includes fasteners designed for welding. Fittings of this type are attached to a component such as a cylinder by welding on one side. The connections come in a black version ( without zinc coating ) so they can be easily welded to any component. Welding fasteners come essentially in three versions: straight connection, elbow connection ( bent at a right angle ) and a bulkhead version ( long weld-on fitting ). Welding fasteners are mainly used by manufacturers of various types of equipment using threaded connections designed for very high pressure. Another type of components intended for welding are spherical ends. Other types of hydraulic weld-on connectors from our offer include, among others: weld-on nipples, for pipe-thread connection, weld-on bulkhead connectors
Weld-on connections for hydraulic power systems
Weld-on connections are components used in the construction and modernization of piping systems in hydraulic power systems. They enable a connection between a pipe or a structural element and the rest of the hydraulic system. This solution is used primarily where one side of the connection is to be permanently joined to the system by welding.
A properly selected weld-on connection allows you to prepare a connection point for a hose, pipe, or another hydraulic fitting component. When choosing, you should primarily take into account the dimensions of the connection, the diameter of the mating pipe, the type of further connection, and the requirements of the specific hydraulic system.
What are hydraulic weld-on connections used for?
Welded connections are used when installing systems where a pipe element needs to be joined with a hydraulic connection. After proper surface preparation, the element is welded into the system, creating a base for connecting further system components.
This solution is useful when carrying out new installations, rebuilding existing systems, and repairing machines and equipment in which hydraulic piping systems are used.
Where are weld-on connections used?
- in hydraulic power piping systems,
- in industrial machines and equipment,
- in hydraulic systems of agricultural and construction machinery,
- in mobile hydraulics,
- during the construction of hydraulic power units and assemblies,
- during the modernization and repair of existing installations.
How to choose a weld-on connection?
The selection should be based on the actual dimensions of the system and the type of elements that are to be joined together. You should not be guided solely by the appearance of the connection. Its dimensions, the geometry of the part intended for welding, and the parameters of the connection side are all important.
- check the diameter of the mating pipe or component,
- verify the dimensions of the connection,
- determine the type of connection on the hydraulic side,
- check the method of sealing the mating elements,
- compare the technical parameters of a specific variant,
- take into account the operating conditions of the entire hydraulic system.
Welded connections in piping systems
Piping systems are commonly used in machine and industrial hydraulics. A weld-on connection allows you to prepare a proper termination of the system in a place where it is necessary to later connect a hydraulic hose, fitting, or other component.
A welded solution is worth considering especially when the design of the machine or the route of the system requires a dedicated connection point. This allows you to adapt the route of the piping to the available space and the design of the device.
Weld-on connection vs. threaded connection
Weld-on connections and typical threaded fittings perform different assembly functions. In the case of a welded element, one part is connected to the system through the welding process. A threaded fitting, on the other hand, uses a previously prepared threaded connection.
The choice of the right solution depends on the construction of the system, assembly possibilities, and the method of routing the lines. Welded, threaded, and pipe connections can be used simultaneously in one hydraulic system.
What to look for during assembly?
Welding of hydraulic system components should be performed using the appropriate technology for the materials used. Of particular importance are surface preparation, axial alignment of elements, and protection of the interior of the system against contaminants generated during assembly work.
After completing the work, the system should be properly cleaned before starting. Contaminants left inside the system can negatively affect the operation of valves, pumps, distributors, and other precision hydraulic components.
Fittings and connectors for building a hydraulic system
Welded connections are one of the groups of elements used when installing hydraulic systems. Depending on the design of the system, they can work with pipes, flexible hoses, and various connection standards.

FAQ - weld-on connections
What is a weld-on connection used for?
A weld-on connection allows for the creation of a connection point in a hydraulic power piping system. One side is intended for joining by welding, and the other enables cooperation with the appropriate system component.
Where are welded connections used?
They are used, among others, in piping systems of industrial, agricultural, and construction machinery, hydraulic power units, and during the modernization of existing systems.
How to choose a weld-on connection?
The dimensions of the mating pipe, the design of the part intended for welding, and the parameters and connection standard on the hydraulic side should be checked.
Does the hydraulic system need to be cleaned after welding?
Yes. Before startup, you must ensure the cleanliness of the installation and the removal of contaminants generated during assembly work, as they can damage or disrupt the operation of the hydraulic system components.
