ISO A poppet quick couplers

Poppet quick couplers (ISO A 7241-1 type) 

ISO A hydraulic poppet quick couplers. The category includes poppet quick coupler plugs and sockets with internal inch threads (BSP). Due to their price and availability, poppet quick couplers are the most popular type of quick couplers used. Used mainly in agriculture, construction machinery, and industry. Quick couplers are used for fast disconnecting and connecting of lines in hydraulic systems. Most often, quick couplers are used for hydraulic oils, however, they can be used for various types of media - depending on the material and seal used. Thanks to the fact that the quick couplers have internal inch threads, we have great flexibility in choosing threads. After using a fitting, the hydraulic socket or plug can be reduced to any external thread ( metric, inch, JIC, OPRFS )

Quick couplers according to ISO 7241-1 A standard

Quick couplers according to international standard 

The ISO 7241-1 standard, specifically its A series (ISO 7241-1 A), specifies interface dimensions and basic performance requirements for general-purpose hydraulic quick couplers. These quick couplers allow for fast and tool-free connection and disconnection of hydraulic lines, which is crucial in systems where a medium under pressure is transmitted in a closed circuit. Series A of this standard is widely used in Europe and preferred worldwide in agricultural and forestry machinery. This standard specifies, among other things, interface dimensions such as the diameters and lengths of individual quick coupler components, as well as basic requirements for their performance, including working pressure and the force required to open the valve at zero internal pressure. It is worth noting that compliance with the ISO 7241-1 A standard ensures interoperability of quick couplers from different manufacturers, which increases their versatility and facilitates integration in various hydraulic systems. Additionally, the use of quick couplers compliant with this standard contributes to increased safety and efficiency in industrial applications. 

Interchangeable ISO A quick couplers

ISO A compliant quick couplers are marked differently by different manufacturers. Each of the groups listed below is compatible with ISO A quick couplers 

• DNP - PAV1
• FASTER - ANV
• SNAP-TITE - 61
• TEMA - TIB

Classification of quick couplers compliant with ISO 7241-1 A

Quick couplers of this type consist of two basic parts: Quick coupler plug (male part) – an element connected to the installation, responsible for a tight connection and fit to the socket. Quick coupler socket (female part) – the part that connects with the plug, ensuring full tightness and easy disconnection of the system. HYDRON's offer includes both plugs and sockets for quick couplers, as well as quick coupler sets that include both elements. This allows for a comprehensive adjustment of the product to the customer's needs and a guarantee of full compatibility.

Application of ISO 7241-1 A quick couplers

Quick couplers of this type are widely used in agricultural, construction, and forestry machinery, as well as in industrial installations. Their compliance with international standards ensures versatility and safety of use, and also allows for easy replacement of components from different manufacturers.

Benefits of using this type of connectors : 

• high availability 
• attractive price 
• compact design
