What is 2-Way Stopcock (Male Luer + Bond-Tube O

Quick Answer

The 2-Way Stopcock (Male Luer + Bond-Tube OD) (CV-033) is a medical plastic component used in IV sets, drip flow control and bag or bottle access. It provides a secure, single-use connection in the fluid path and is molded from polycarbonate. Baixin Bio supplies it in standard form and with OEM/ODM customization.

Definition

The term 2-way stopcock (male luer + bond-tube od) refers to a precision component within IV sets, drip flow control and bag or bottle access. It defines how a fluid line connects, branches, seals or regulates, and it is molded to tight tolerances so the interface performs the same way across an entire production lot.

Because the part sits directly in the fluid path, three things matter most: a dependable seal, dimensional consistency from part to part, and a material that is compatible with the fluid and the chosen sterilization method.

Seen in context, the component is one link in a chain. A complete single-use set joins several molded parts into one continuous fluid path, and each junction has to seal and hold. Because the interfaces are standardized, an assembler can combine catalog parts with confidence rather than designing every joint from scratch.

About This Component

The 2-Way Stopcock (Male 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

The practical advantages of 2-way stopcock (male luer + bond-tube od) cluster around safety, consistency and supply:

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

Taken together, these are the reasons device makers standardize on molded medical components rather than improvising connections: the part is predictable, documented and available at volume, which keeps the finished device safe and the production line moving.

Common Applications

You will find 2-way stopcock (male luer + bond-tube od) across a range of single-use fluid-handling assemblies, including:

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

The common thread is that every one of these settings needs junctions it can trust. A standardized, single-use component delivers that trust at scale: the same interface, the same seal and the same material behavior across an entire production lot, so the clinical team and the device maker are not relying on a one-off fitting at a critical point in the line.

How to Specify and Choose

A good specification answers a short list of questions up front:

The working pressure the junction must hold without leaking or separating
The fluid and its chemical compatibility with the candidate resin
The inner and outer diameters of the tubing the part bonds to
The sterilization method the finished device will undergo
Whether the part is single-use or intended for limited reuse

Getting these settled early means the first samples are usable and the program moves to volume faster. When a standard part does not fit, the same variables become the brief for an OEM or ODM tooling project.

Industry Standards

Two standards questions dominate this category: connection geometry and sterilization. Connection geometry is increasingly defined by the ISO 80369 series, which separates applications so incompatible lines cannot mate; sterilization is handled by validated EO, gamma or steam autoclave processes matched to the resin and the device.

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.
