1/2″ Body Size Carbon Steel ISO A Quick Couplings are a type of coupling designed for quick and easy connection and disconnection of lines or hoses, typically in hydraulic applications. They’re made of carbon steel for affordability and strength and adhere to the ISO A standard for intercompatibility with other ISO A couplings. These couplings feature poppet valves for automatic shut-off when disconnected, preventing fluid leakage.
Benefits
- Quick and easy to connect and disconnect
- Automatic shut-off for leak prevention
- Affordable compared to stainless steel options
- Durable and reliable for many applications
- Interchangeable with other ISO A couplings

Applications
1/2″ Body Size Carbon Steel ISO A Quick Couplings are typically used in hydraulic applications where frequent connection and disconnection of lines or hoses is required, and where the pressure and temperature demands fall within their limitations.
Construction equipment:
- Connecting hydraulic lines on skid steer loaders for attachments like augers, hammers, and trenchers.
- Connecting hoses for water and additives to concrete mixers.
- Connecting hydraulic lines on backhoes and excavators for attachments like buckets, augers, and rippers.
Agriculture:
- Connecting hydraulic lines on tractors for attaching implements like plows, planters, and sprayers.
- Connecting power take-off (PTO) shafts to implements on tractors.
Other applications:
- Connecting hydraulic lines on machine tools like presses, CNC machines, and robots.
- Connecting hydraulic lines on industrial equipment like forklifts, cranes, and presses.
- Connecting hydraulic lines on mobile hydraulics like landscaping equipment, forestry machinery, and snow removal equipment.
