What applications is 3-Way Stopcock (Female Lue

Quick Answer

The 3-Way Stopcock (Female Luer + Bond-Tube OD) (CV-037) suits IV sets, drip flow control and bag or bottle access and similar single-use fluid-handling assemblies. It is molded from polycarbonate for dependable connections. Baixin Bio offers it as a standard or customized part.

Definition

A 3-way stopcock (female luer + bond-tube od) is one of the small standardized parts that make a medical fluid path work. Its job is to connect, seal or control flow between two segments of a line, and it is manufactured from device-qualified plastics for reliable single-use performance.

The component is small, but it carries real responsibility: a poor seal or an out-of-tolerance dimension can compromise an entire single-use assembly, which is why medical molders control material, tooling and process tightly.

To put it in context: a disposable fluid-handling device is rarely one molding. It is a chain of small components — connectors, valves, chambers, clamps, caps and tubing — assembled into a single path. Standard interfaces are what let those components come from a catalog and still fit, which is the whole reason this category of part exists.

About This Component

The 3-Way Stopcock (Female Luer + Bond-Tube OD) is supplied as a single-use molded part for IV sets, drip flow control and bag or bottle access. Its interface follows standard conventions so it mates predictably with compatible components, and it is produced in polycarbonate by default, with other medical-grade resins available on request.

Like all Baixin Bio components, it can be customized for material, color, dimensions, packaging and assembly. For a precise specification — exact dimensions, tolerances, sterilization validation, packaging counts and minimum order quantity — request a drawing and samples through the inquiry form.

Key Advantages

For device assemblers specifying 3-way stopcock (female luer + bond-tube od), the benefits that matter most are reliability and repeatability:

Medical-grade resin selected for fluid compatibility
Dimensional consistency across production lots
Smooth fluid-contact surfaces for reliable connection
Available in multiple materials and colors
Supports OEM and ODM customization of dimensions and packaging
High-volume manufacturing with stable quality

None of these advantages matter in isolation; their value is cumulative. A part that seals well but drifts dimensionally, or one that is consistent but slow to supply, fails the assembler. The point is to get all of them at once, reliably, lot after lot.

Common Applications

Typical applications for 3-way stopcock (female luer + bond-tube od) span the disposable device landscape:

Enteral feeding sets
Laboratory fluid handling
Irrigation sets
Disposable diagnostic devices
Syringe and pump connections

What links these applications is risk. Each one moves fluid into or out of a patient or a sample, so a leak, a wrong connection or a contaminated surface has consequences. Standardized single-use components reduce that risk by making every junction predictable and by being discarded rather than reprocessed, which is the safer default for most modern disposable devices.

How to Specify and Choose

Specifying the right part is mostly about matching a handful of variables to your assembly:

Color coding or opacity requirements for the assembly
Packaging format and order volume for the program
The connection standard the mating part uses (luer slip, luer lock or a specific ISO 80369 series)
The working pressure the junction must hold without leaking or separating
The fluid and its chemical compatibility with the candidate resin

With those answers in hand, a supplier can confirm a standard part or scope a custom one without back-and-forth. Sharing a drawing or a physical sample removes the remaining ambiguity.

Industry Standards

The relevant standards work is centered on ISO 80369, the small-bore connector series designed to prevent dangerous misconnections across IV, enteral, respiratory and other applications. Alongside connection standards, material biocompatibility and a validated sterilization method (EO, gamma or autoclave) define whether a component is fit for medical use.

For polycarbonate components, the practical sterilization options are gamma and ethylene oxide (EO); the choice is confirmed against the finished device and its validated process.

The reason the standards landscape moved toward ISO 80369 is patient safety: when every line used the same luer taper, it was physically possible to connect, say, an enteral line to an intravenous one. The newer series give different applications deliberately incompatible geometries so a dangerous misconnection cannot be made by accident. For a component maker, that means confirming which series an application requires before specifying a part.
