Standard-Bore IV Extension Sets – Reliable Flow for Everyday IV Therapy

No product defined

No product defined in this category.

Standard-bore IV extension sets provide the higher-flow capacity needed for routine hydration, maintenance fluids, and many IV medications. Compared with microbore tubing, the larger internal diameter supports faster flow rates while maintaining dependable line control and secure connectivity. These sets allow clinicians to position pumps and access points conveniently without compromising flow performance.

This category includes a wide range of standard-bore extension configurations designed for use with peripheral IV lines, central venous catheters, and primary administration sets. Options vary by length, priming volume, and port layout to support med-surg, emergency, ICU, perioperative, and outpatient infusion workflows. All sets are sterile, with latex-free and DEHP-free options available.

What You Can Order in This Category

  • Short Standard-Bore Extensions (4–20 inches) — For tight setups, bedside access, and adding minimal length without excessive priming volume.
  • Medium-Length Extensions (20–60 inches) — General-purpose solutions for standard med-surg and telemetry rooms where pumps are mounted at the bedside or on IV poles.
  • Longer Standard-Bore Extensions — Provide flexibility for equipment positioning around beds, stretchers, or procedure tables in ER, ICU, and OR environments.
  • Extensions with Injection or Needle-Free Ports — Support intermittent medication injection, flushing, or blood sampling without breaking the line.
  • Extensions with Back-Check Valves or Flow Control — Help prevent backflow and support controlled infusions in multi-line setups.

Technical Specifications Available

  • Tubing bore: Standard-bore internal diameter for higher flow rates than microbore lines, suitable for routine hydration and many IV drugs.
  • Lengths: Typically range from short add-on segments (4–12 inches) to extended lengths around 60 inches or more for complex setups.
  • Priming volumes: Higher than microbore extensions but optimized to balance flow performance and medication conservation.
  • Connectors: Male and female luer lock options, rotating luers, and needle-free connectors compatible with most IV sets and catheters.
  • Safety features: Clamp options, back-check valves, and needle-free access ports to help reduce contamination and needlestick risk.

Where Standard-Bore Extension Sets Are Used

Standard-bore IV extension sets are widely used across hospital med-surg units, telemetry floors, emergency departments, step-down units, infusion centers, and long-term care facilities. They are well suited for hydration, antibiotics, electrolytes, and many common medications where reliable flow and easy bedside access are priorities. By adding length and access points without excessive line manipulation, these sets support safer infusions and more efficient workflows for both IV pumps and gravity systems.
