The ST DSO PT Series is an advanced range of double shutoff quick couplings engineered for precision fluid transfer in demanding environments. Designed with a poppet valve mechanism, the coupling ensures complete sealing on both ends during disconnection — eliminating any fluid loss or air intake.
Its single-touch connection enables fast, secure, and hassle-free operation, making it ideal for systems that require frequent coupling and uncoupling. Constructed from robust stainless steel or brass, the ST DSO PT Series guarantees long life, corrosion resistance, and consistent performance under high pressure.
Available in sizes from 1/4“ to 2“, this series serves diverse industries where clean, controlled, and leak-proof fluid transfer is essential.
