The DSO PT Series (Plastic Type) is a precision-engineered range of double shutoff quick couplings designed for pharmaceutical, cleanroom, and hygienic fluid transfer applications. Made from high-purity engineering plastics, these couplings ensure clean, non-reactive, and corrosion-free operation in sensitive environments.
Equipped with a dual poppet valve system, the DSO PT Series automatically seals both ends during disconnection, preventing fluid leakage, air entry, and contamination. The single-touch coupling mechanism allows fast and easy operation — perfect for sterile setups where simplicity and cleanliness are essential.
Constructed from medical- and food-grade plastics such as acetal, polypropylene, or PVDF, the DSO PT Series offers excellent chemical resistance, smooth flow characteristics, and low particle generation. Its non-metallic design makes it ideal for applications where metal contact must be avoided.
Available in sizes from 1/8“ to 2“, these couplings deliver reliable, repeatable, and hygienic performance across a wide range of clean fluid systems.
