What material is 3-Way Stopcock (Female Luer +

Quick Answer

The 3-Way Stopcock (Female Luer + Bond-Tube OD) (CV-037) is molded from polycarbonate, chosen for the part's connection and fluid-path requirements. The material supports the sterilization and compatibility needs of IV sets, drip flow control and bag or bottle access. Custom material and color are available from Baixin Bio.

Definition

At its core, a 3-way stopcock (female luer + bond-tube od) 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.

What separates a medical-grade part from a generic fitting is repeatability. Sealing surfaces are smooth and consistent, dimensions hold across the lot, and the resin is selected for fluid compatibility and sterilization.

It helps to picture where the part sits. A finished single-use device — an IV set, a transfer line, a dialysis circuit — is an assembly of molded plastic pieces joined into one fluid path. Each piece has a narrow job, and the value of standardization is that pieces from a catalog snap together predictably, so an assembler can design around known interfaces instead of bespoke fittings.

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:

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
Leak-resistant seal that holds under normal line pressure

In short, the component earns its place by being unremarkable in the best way: it fits, it seals, it is available, and it behaves the same every time, so engineering attention can go to the device rather than the fitting.

Common Applications

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

Syringe and pump connections
IV infusion sets
Blood and fluid transfer lines
Hemodialysis circuits

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:

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
Color coding or opacity requirements for the assembly

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.

Much of the modern standards work exists to prevent misconnection. Historically a single luer taper served many applications, which made cross-connections physically possible; the ISO 80369 series assign distinct geometries to different uses so incompatible lines simply will not mate. When you specify a connector, identifying the correct series for the application is therefore a safety decision, not just a fit decision.
