What is Double-Ended Straight Plug used for

Quick Answer

The Double-Ended Straight Plug (BHM-16) is a medical plastic component used in sealing and protecting luer ports. It provides a secure, single-use connection in the fluid path and is molded from polycarbonate. Baixin Bio supplies it in standard form and with OEM/ODM customization.

Definition

The term double-ended straight plug refers to a precision component within sealing and protecting luer ports. 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.

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 Double-Ended Straight Plug 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

Where double-ended straight plug earns its place, it is for a handful of practical reasons:

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
Standardized interface that interoperates with compliant luer components

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

The settings that rely on double-ended straight plug include:

IV infusion sets
Blood and fluid transfer lines
Hemodialysis circuits
Enteral feeding sets

What links these applications is risk. Each one moves fluid into or out of a patient or a sample, so a leak, a wrong connection or a contaminated surface has consequences. Standardized single-use components reduce that risk by making every junction predictable and by being discarded rather than reprocessed, which is the safer default for most modern disposable devices.

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

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.

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

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.

Is double-ended straight plug 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.
