ISO A Quick Couplings

ISO A quick couplers, also known as ISO 7241-1 Series A couplers, are hydraulic connectors designed for general-purpose fluid transfer applications. These couplers are known for their robust construction, reliable performance, and ease of use. They feature a poppet valve design, which provides a secure and leak-resistant connection, even under high pressure. ISO A quick couplers are commonly used in agriculture, construction, and industrial machinery. They are standardized to ensure compatibility and interchangeability among different manufacturers, making them a versatile choice for various hydraulic systems.

ISO 5675 provides additional requirements and specifications based on the ISO 7241 Series A standard for agricultural quick couplers. These couplers are specifically designed to meet the rigorous demands of agricultural machinery and equipment. It typically covers two main sizes: 1/2 inch and 3/4 inch. These sizes are the most commonly used in agricultural machinery, providing the necessary flow rates and pressure capacities for various hydraulic applications. The ISO 5675 standard ensures that these couplers offer reliable performance, durability, and compatibility with different equipment, making them suitable for the rigorous demands of the agricultural sector. The AG Series quick couplers are specially designed to meet the ISO 5675 standard, ensuring they are perfectly suited for agricultural applications.

Other Quick Couplings

Other quick couplings refer to those designed by some manufacturers, but have been globally interchangeable, but have not been collected by ISO standard organizations. These quick couplings, when produced by different manufacturers, have all adopted the same connection standards. So to a certain extent, they are also half-to-half interchangeable.
