What is 3-Way Stopcock (Female Luer + Bond-Tube

Quick Answer

The 3-Way Stopcock (Female Luer + Bond-Tube ID) (CV-036) 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

At its core, a 3-way stopcock (female luer + bond-tube id) is a molded plastic component that creates or controls a connection in a medical fluid line. It is engineered so that tubing, syringes, devices and accessories join with a predictable, leak-resistant fit, and it is produced as a single-use part from medical-grade thermoplastics.

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 3-Way Stopcock (Female Luer + Bond-Tube ID) 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

Where 3-way stopcock (female luer + bond-tube id) earns its place, it is for a handful of practical reasons:

Available in multiple materials and colors
Supports OEM and ODM customization of dimensions and packaging
High-volume manufacturing with stable quality
Compatibility with common sterilization methods
Standardized interface that interoperates with compliant luer components

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

The settings that rely on 3-way stopcock (female luer + bond-tube id) include:

Hemodialysis circuits
Enteral feeding sets
Laboratory fluid handling
Irrigation sets

Across all of these uses, the underlying requirement is the same: a connection that is secure, leak-resistant and safe to make once and discard. That is why standardized, single-use molded components dominate the category — they remove variability from the most failure-prone part of a fluid path, the junction, and they let a device be assembled quickly and qualified as a unit.

How to Specify and Choose

Specifying the right part is mostly about matching a handful of variables to your 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
The inner and outer diameters of the tubing the part bonds to

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

Small-bore connectors for liquids and gases are governed by the ISO 80369 family, which is progressively replacing the historical luer standard to reduce the risk of misconnection between different clinical applications. Medical-grade resins are selected and documented for biocompatibility, and finished components are sterilized by validated methods such as ethylene oxide (EO), gamma irradiation or steam autoclave depending on the material.

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.
