The DSO PT Series is a high-precision range of double shutoff quick couplings developed for applications where leak-free and clean fluid transfer is critical. Designed with a dual poppet valve system, it seals both sides automatically during disconnection — preventing fluid loss and air ingress even under pressure.
The single-touch connect and release mechanism offers smooth, effortless operation, making it ideal for setups that require quick changeovers or frequent testing cycles. Constructed from high-grade stainless steel or brass, the DSO PT Series provides exceptional durability, corrosion resistance, and long service life in demanding environments.
Engineered for optimal flow with minimal pressure drop, these couplings maintain consistent performance in hydraulic, pneumatic, and precision fluid control systems. Available in sizes from 1/4“ to 2“, they deliver flexibility and compatibility across multiple industries.
