ISO-A Poppet-Type Hydraulic Quick Coupler Sets (Plug + Socket Sets)

Sets of standard poppet-type quick couplers ISO-A (ISO 7241-1 series A) are complete, ready-to-install solutions for power hydraulic systems. By purchasing a set, you receive a perfectly matched hydraulic socket (female part) and quick coupler plug (male part).

Choosing a ready-made set guarantees 100% compatibility of both elements, eliminates the risk of error when selecting threads or seals, and significantly speeds up assembly work when crimping hydraulic hoses.

Advantages and Characteristics of ISO-A Sets

• Guarantee of compatibility and tightness: The perfect fit of the socket and plug prevents leaks and premature wear of system components.
• Wide market interchangeability: Sets manufactured according to the ISO-A standard are fully interchangeable with quick couplers from other recognized manufacturers (e.g., Faster, Stucchi, DNP, Parker).
• Durability and high quality of materials: Galvanized steel bodies guarantee high resistance to corrosion and atmospheric factors. NBR sealing enables reliable operation in the temperature range from -25°C to +100°C.
• Operational safety: The safety factor is 4:1, and the pressure strength reaches up to 400 bar for plugs and up to 250 bar for sockets (depending on the size).
• Breakaway (Push-Pull) function in sockets: Allows for automatic disconnection of the plug in case of unexpected hose tension, protecting the installation against rupture and oil leakage.

Wide Application of Quick Coupler Sets

ISO-A poppet-type coupler sets are valued wherever reliability and high frequency of connecting and disconnecting equipment matter:

• Agricultural machinery: Connecting a tractor with a plow, round baler, tipper trailer, sprayer, or front loader (TUR).
• Construction and road machinery: Powering attachments in mini-excavators, loaders, and cranes.
• Municipal vehicles and transport: Hydraulic systems in garbage trucks, snow plows, and loading platforms.
• Stationary industry: Hydraulic power units and aggregates, as well as portable production lines.
