The Air-Source Connector (JT-044) suits IV infusion sets and fluid-transfer lines and similar single-use fluid-handling assemblies. It is molded from medical PVC for dependable connections. Baixin Bio offers it as a standard or customized part.
Definition
The term air-source connector 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.
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.
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 Air-Source Connector 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 medical PVC 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 air-source connector, the benefits that matter most are reliability and repeatability:
- 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
- Compatibility with common sterilization methods
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 air-source connector span the disposable device landscape:
- Disposable diagnostic devices
- Syringe and pump connections
- IV infusion sets
- Blood and fluid transfer lines
- Hemodialysis circuits
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
When you select a component, work through these variables before requesting a quote:
- 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
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
The relevant standards work is centered on ISO 80369, the small-bore connector series designed to prevent dangerous misconnections across IV, enteral, respiratory and other applications. Alongside connection standards, material biocompatibility and a validated sterilization method (EO, gamma or autoclave) define whether a component is fit for medical use.
For medical PVC components, the practical sterilization options are EO and gamma; 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
Can I request samples?
Yes. Samples and drawings are welcome and recommended before committing to volume. Use the inquiry form to request them.
Is air-source connector available for OEM or ODM projects?
Yes. Baixin Bio manufactures to drawings and samples, customizing material, color, dimensions, packaging and assembly. Send your specification for a quote.
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.
