The Barb Straight Connector (Equal / Reducing) (JT-033) mates with its counterpart to form a secure, leak-resistant junction in the fluid path of IV infusion sets and fluid-transfer lines. It is molded from polycarbonate. Baixin Bio produces it for high-volume assembly.
Definition
A barb straight connector (equal / reducing) 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.
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 Barb Straight Connector (Equal / Reducing) 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
Where barb straight connector (equal / reducing) earns its place, it is for a handful of practical reasons:
- 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
The settings that rely on barb straight connector (equal / reducing) include:
- IV infusion sets
- Blood and fluid transfer lines
- Hemodialysis circuits
- Enteral feeding 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
A good specification answers a short list of questions up front:
- 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
- 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
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
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.

Frequently Asked Questions
What materials are used?
Depending on the part, medical-grade PC, PP, PVC, ABS, PE or POM is used, selected for the connection method, fluid path and sterilization requirement.
How is it sterilized?
Components are compatible with validated single-use sterilization such as ethylene oxide, gamma irradiation or steam autoclave, depending on the resin. Confirm the method for your device.
Is it compatible with ISO 80369?
Luer interfaces follow small-bore connector conventions. Confirm exact ISO 80369 series compatibility for your application with Baixin Bio before specifying.
What order volumes are supported?
Baixin Bio supplies disposable device assemblers in production volumes, with consistent lot-to-lot quality and export-friendly communication.
Can I request samples?
Yes. Samples and drawings are welcome and recommended before committing to volume. Use the inquiry form to request them.
