Dry Link® Dry Disconnect Couplings

When product loss and product spills are unacceptable, dry-disconnect valves may be the ideal solution. CSI offers Dry Link dry disconnect "dry break" hose couplings for bulk transfer of liquids, and high-containment split-butterfly valves for powders. Dry Link's sanitary high-purity line of couplings are specified by all major pharmaceutical, biotechnology and food companies.

Dry disconnect couplings utilize a two-part design. Together, the coupler and adapter portions operate as a shutoff valve, facilitating liquid transfer in applications like bulk unloading. When the valve is closed, the two portions can be separated without any drips or product loss.


Whether you are a small-scale lab, medium sized batch processor, or large manufacturer, Dry Link offers the right dry disconnect coupling to suit your needs, with full support and validation from start to finish. Dry Link couplings are an ideal solution for transferring costly materials, where even small product losses are unacceptable, or hazardous materials, where spills present a safety concern.

Standard Design

Dry Link sanitary couplings are the only true sanitary, drip-free couplings currently available. Their simple butterfly design is sanitary and cleanable, and the smooth mirror-polished bore has no voids, dead spaces, crevices, or fillers that could trap bacteria. Easily drainable and sanitized using steam or other methods such as clean-in-place (CIP) or sterilization-in-place (SIP), Dry Link sanitary couplings are routinely specified in pharmaceutical, biotech, semiconductor, food, and cosmetic industries where ultra cleanliness is required.Standard sanitary couplings are supplied with Tri-Clover® ends and with wetted internal components polished to 20 RA micro-inch (0.50 RA micron) mirror finish. A wide choice of sizes, body, and seal materials, end connections and with full material test certifications (MTR), Food and Drug Administration (FDA), and U.S. Pharmacopeial Convention (USP) certifications are available. Additional options include extra fine inside polish and outside polish to matte finish.
