What tubing size works with Male Plug (Large)

Quick Answer

The Male Plug (Large) (BHM-02) is offered for common tubing sizes used in sealing and protecting luer ports; exact inner/outer diameters can be specified. It is molded from polycarbonate. Baixin Bio customizes dimensions on request.

Definition

At its core, a male plug (large) is a molded plastic component that creates or controls a connection in a medical fluid line. It is engineered so that tubing, syringes, devices and accessories join with a predictable, leak-resistant fit, and it is produced as a single-use part from medical-grade thermoplastics.

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 Male Plug (Large) is supplied as a single-use molded part for sealing and protecting luer ports. 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 male plug (large) 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

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

In practice, male plug (large) appears wherever a controlled fluid connection is needed:

Laboratory fluid handling
Irrigation sets
Disposable diagnostic devices
Syringe and pump connections

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 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
Whether the part is single-use or intended for limited reuse

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

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.

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.

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 male plug (large) 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.
