ISO B quick couplings refer to hydraulic couplings that comply with the ISO 7241-1 B standard. This standard, like ISO A, ensures dimensional compatibility and performance specifications across different manufacturers, but ISO B couplings have some distinct features and are designed for different applications.

• Poppet valve design: Ensures low spillage during connection and disconnection, reducing fluid loss and preventing contamination.
• Interchangeability: Similar to ISO A, ISO B couplings are designed to be interchangeable between manufacturers as long as they follow the ISO 7241-1 B standard.
• Applications: Primarily used in industrial settings like chemical processing, food manufacturing, and fluid transfer where minimizing contamination is important.

While ISO A couplings are often used in agricultural and construction environments, ISO B couplings are more common in industrial applications that demand higher cleanliness and spillage control.
