Straight female couplings AA metric

The category includes straight couplings with two swivel nuts - this type is also referred to as a straight female coupling AA metric. Couplings manufactured according to DIN 2353. Straight coupling with metric thread nuts on both sides and a 24° seat. Used in hydraulics for connections in oil systems. Made of free-cutting steel, covered with an anti-corrosive zinc layer in white passivation. Available in a light version (L – up to 16 MPa) and a heavy version (S – up to 32 MPa). We also offer straight couplings with inch and JIC threads. Couplings are available in versions with identical threads and in reduction versions with two different thread sizes. Execution: high-grade free-cutting steel covered with zinc plating. Alternative designation for this type of coupling: Straight female coupling / Straight coupling with swivel nut. Straight male connector type: Tn 498; Straight female coupling / Straight coupling with swivel nut.

Metric male thread (GZ) in power hydraulics

In the context of straight couplings AA metric, the term gz hydraulics refers to elements equipped with metric male thread (GZ), which works with components having a metric female thread. Metric male (GZ) couplings are commonly used in power hydraulics in industrial and agricultural machinery, where connections compliant with metric standards dominate. Depending on the coupling design, the connection tightness is achieved through a sealing cone, flat seal, or O-ring seated in the socket. Solutions with metric male (GZ) thread enable reliable assembly, easy service, and maintain compatibility with popular European hydraulic standards. Couplings in this execution are a fundamental element of many hydraulic systems available in the Hydron offer.

Application of straight hydraulic couplings type AA

Couplings are usually used to connect two elements with external threads. Couplings are also used if we need to move (distance) two elements relative to each other. Reducing couplings are used to connect 2 elements of a hydraulic system to each other. Application of straight AA couplings in power hydraulics: Straight AA couplings are widely used in power hydraulics systems, where they play a key role in connecting high-pressure hoses. Their reliability and tightness affect the efficiency of the entire installation and increase the safety of hydraulic machines and equipment. They are used in industries such as: Heavy industry; Automotive and transport; Agricultural and construction machinery; Hydraulic systems in specialized vehicles. 

Metric adjustable couplings AA

What are straight AA couplings? Straight AA couplings are connector elements used in power hydraulics systems that provide durable and tight connections of hydraulic hoses. Thanks to their simple design and high precision, they are a reliable solution for installations requiring solid and fail-safe components. The variety of available variants allows for precise matching to a specific installation, which translates into the tightness and reliability of the hydraulic system.

How to choose the right straight AA couplings?

Choosing the right straight AA coupling is important to ensure efficient operation of the hydraulic system. When choosing, it is worth paying attention to: Diameter and thread type – matching the specifics of the hydraulic installation prevents leaks and technical problems. Material – depending on the working conditions, you can choose couplings made of galvanized steel, stainless steel or brass, which allows them to be adapted to work in environments exposed to high temperatures or corrosive substances. Working pressure – choosing elements adapted to pressure parameters ensures the safety and longevity of the installation.
