The Y-Type Luer 4-Way Connector (Bond-Tube) (JT-034) is a medical plastic component used in IV infusion sets and fluid-transfer lines. 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 y-type luer 4-way connector (bond-tube) refers to a precision component within IV infusion sets and fluid-transfer lines. 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.
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.
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 Y-Type Luer 4-Way Connector (Bond-Tube) is supplied as a single-use molded part for IV infusion sets and fluid-transfer lines. 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 reasons y-type luer 4-way connector (bond-tube) is specified come down to a few concrete advantages:
- 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
In practice, y-type luer 4-way connector (bond-tube) appears wherever a controlled fluid connection is needed:
- Disposable diagnostic devices
- Syringe and pump connections
- IV infusion sets
- Blood and fluid transfer lines
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
A good specification answers a short list of questions up front:
- 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
- Packaging format and order volume for the program
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
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.
