The Air-Source Connector (JT-044) is molded from medical PVC, chosen for the part's connection and fluid-path requirements. The material supports the sterilization and compatibility needs of IV infusion sets and fluid-transfer lines. Custom material and color are available from Baixin Bio.
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.
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 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
The reasons air-source connector is specified come down to a few concrete advantages:
- Single-use design that supports sterile, disposable workflows
- Medical-grade resin selected for fluid compatibility
- 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
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
In practice, air-source connector appears wherever a controlled fluid connection is needed:
- Hemodialysis circuits
- Enteral feeding sets
- Laboratory fluid handling
- Irrigation sets
- Disposable diagnostic devices
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
When you select a component, work through these variables before requesting a quote:
- 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
Once these are defined, sample qualification against your own process is the last step before volume. If no catalog part matches, these same inputs drive a custom mold.
Industry Standards
From a compliance standpoint, the component sits at the intersection of connector standards and material standards. The ISO 80369 family governs small-bore connection geometry to prevent misconnection, while biocompatibility documentation and a validated sterilization route — EO, gamma or autoclave — establish that the molded material is acceptable for its intended contact.
For medical PVC components, the practical sterilization options are EO and gamma; 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.
