The DSO PT Series is a robust range of high-pressure double shutoff quick couplings engineered for leak-free and secure fluid transfer in demanding industrial environments. Featuring a precision poppet valve mechanism, it automatically seals both sides upon disconnection, ensuring zero fluid loss and no air ingress even under high system pressures.
Built to handle operating pressures up to 350 bar, the DSO PT Series is constructed from high-grade stainless steel or brass for superior strength, corrosion resistance, and reliability. The single-touch connection enables quick and effortless coupling, minimizing downtime in hydraulic, test, and control systems.
Designed for low pressure drop and high flow efficiency, these couplings are ideal for critical systems where performance and cleanliness are essential. Available in sizes from 1/4“ to 2“, the DSO PT Series provides a perfect balance of safety, durability, and operational convenience.
