The ST SSO Series is a precision-engineered single shutoff quick coupling designed for controlled and clean fluid transfer in pharmaceutical, laboratory, and cleanroom environments. It features a built-in shutoff valve that automatically seals the fluid path upon disconnection, ensuring no leakage, no air ingress, and contamination-free operation.
With a single-touch operation, the ST SSO Series provides quick and easy connect/disconnect functionality — perfect for systems requiring frequent changeovers or maintenance without compromising cleanliness. Constructed from high-quality stainless steel (AISI 316L), these couplings offer excellent corrosion resistance, smooth internal surfaces, and long service life even under repeated use.
Available in sizes from 1/4“ to 2“, the ST SSO Series delivers reliability and efficiency in low- to medium-pressure clean fluid systems.
