Discofix Stopcocks by B. Braun

When you're managing an IV line, the reliability of every connection point matters. Discofix stopcocks from B. Braun are precision-engineered three-way and multi-port control valves that regulate fluid flow between infusion lines, syringes, and pressure monitoring setups. Clinicians choose Discofix for its smooth handle rotation, clear directional indicators, and a tight seal that holds up under repeated adjustment — the details that keep infusion therapy accurate and free of leaks or accidental backflow.

This collection centers on two configurations built for the same 2-port, 0.26 mL priming volume but differing in how they attach to the line:

• B. Braun Discofix Stopcock with Slip Connector (455991) — a push-fit slip design for quick, straightforward connections where speed matters.
• B. Braun Discofix Stopcock with Spin-Lock Connector (456003) — a threaded luer-lock style that secures firmly to prevent inadvertent disconnection during patient movement or transport.

Both share the low priming volume that helps limit medication dead space, and both feature the color-coded handle and lipid-resistant housing that make Discofix a dependable choice for high-acuity environments. Deciding between them usually comes down to your protocol: slip connectors suit fast-turnover procedural settings, while spin-lock connectors are preferred wherever a guaranteed locked seal is required, such as pressure lines or ambulatory care.

Discofix stopcocks are single-use and designed for compatibility with standard luer fittings, so they integrate cleanly into existing IV administration sets. For a complete setup, pair them with related supplies across our IV Supplies category, or explore the broader range at Honest Medical.
