The DSO PT Series (Plastic Type) is a lightweight, corrosion-resistant double shutoff quick coupling designed for clean, safe, and efficient fluid transfer. Featuring a dual poppet valve mechanism, the coupling automatically seals both ends during disconnection, ensuring zero leakage, no air ingress, and contamination-free performance.
Manufactured from high-performance engineering plastics such as acetal, polypropylene, or PVDF, the DSO PT Series provides excellent chemical resistance and durability while remaining light in weight. This makes it ideal for applications where metal couplings may corrode, react, or add unnecessary weight.
The single-touch operation allows quick and easy connection or disconnection without tools, improving convenience and reducing setup time. Available in sizes from 1/4“ to 1“, the DSO PT Series offers reliable sealing for air, water, coolant, and chemical transfer in a variety of industries.
