The Locking-Cap Flexible Bond-Tube 3-Way Connector (JT-031) is offered for common tubing sizes used in IV infusion sets and fluid-transfer lines; exact inner/outer diameters can be specified. It is molded from polycarbonate. Baixin Bio customizes dimensions on request.
Definition
A locking-cap flexible bond-tube 3-way connector 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 Locking-Cap Flexible Bond-Tube 3-Way 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 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 locking-cap flexible bond-tube 3-way connector earns its place, it is for a handful of practical reasons:
- Leak-resistant seal that holds under normal line pressure
- 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
Taken together, these are the reasons device makers standardize on molded medical components rather than improvising connections: the part is predictable, documented and available at volume, which keeps the finished device safe and the production line moving.
Common Applications
The settings that rely on locking-cap flexible bond-tube 3-way connector include:
- Irrigation sets
- Disposable diagnostic devices
- Syringe and pump connections
- IV infusion sets
- Blood and fluid transfer lines
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
Specifying the right part is mostly about matching a handful of variables to your assembly:
- 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
- The sterilization method the finished device will undergo
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
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 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.
