Industrial S75-4 Hydraulic Quick Connect Coupling

SafeWay's S75-4 is a 1/2" NPT female quick-connect coupling (socket) designed for connect-under-pressure operation in industrial hydraulic systems. The steel-bodied S75-4 accepts SafeWay S70-series plugs and provides a 1/2"-14 thread interface rated up to 3000 psi, making it suitable for high-demand hydraulic circuits. This model uses a push-to-connect locking mechanism and a poppet-style seal to ensure reliable mating and disconnection while the system remains pressurized. With its 1/2" NPT female port, the coupling body pairs with the corresponding male tip in the same series to form a secure, durable connection in rugged environments. Typical applications include general-purpose industrial machinery, hydraulic power units, agricultural equipment, and other hydraulic systems that require fast, tool-free connection and disconnection without depressurizing the line.
