Sanitary Dry Disconnect Couplings for Ultra-Clean Applications
Start operating smarter and more efficiently with fluid transfer solutions engineered to provide the highest levels of purity. JHFOSTER provides Control Devices Dry Link sanitary couplings, the industry’s only true drip-free solutions designed to support compliance and product integrity in sensitive environments.
What is a Sanitary Coupling?
In critical processing, sanitary means more than just being clean. Our sanitary range features products with an internal 20RA micro-inch mirror finish (with optional electropolish) and a smooth-bore design. This eliminates crevices where bacteria can grow, ensuring your process remains contamination free and compliant with U.S. Food and Drug Administration (FDA) and United States Pharmacopeia (USP) standards.
Precision Applications for Sanitary Environments
Control Devices’ Dry Link sanitary couplings are trusted where containment and product integrity are non-negotiable. Common use cases include:
Pharmaceutical and Biotech: Safe transfer of sensitive media and active ingredients without the risk of external exposure.
Food and Beverage: Maintaining sterile conditions for ingredients, preventing cross contamination and minimizing costly waste from spills.
Cosmetic Manufacturing: Ensuring batch consistency by preventing cross contamination between product lines.
