ISO 80369-7 Male Plug Gauge for Testing Female Luer Connectors

ISO 80369-7 Male Plug Gauge for Testing Female Luer Connectors

The ISO 80369-7 Male Plug Gauge is used to verify the internal mating geometry of female Luer connectors. Instead of applying pressure, axial load or stress cracking conditions, this gauge helps the user check whether a female Luer connector accepts a controlled male plug / Luer taper interface as expected.

This product should not be confused with ISO 80369-7 Figure C.2, C.4 or C.6 male reference connectors. Those Annex C reference connectors are used in specific performance test configurations, while the Male Plug Gauge is mainly used for dimensional and fit verification based on Luer connector geometry.

For medical device manufacturers, laboratories and factory QC teams, the Male Plug Gauge is useful for checking female Luer connector samples before further functional testing. It can help identify obvious dimensional or mating issues before using ISO 80369-20 leakage, air leakage or axial load test equipment.

Standard Background and Correct Positioning

ISO 80369-7 includes dimensional requirements for Luer connectors and provides Luer connector dimension figures and tables in Annex B. The Male Plug Gauge is best understood as a practical inspection gauge based on those Luer connector dimensional requirements.

It is different from ISO 80369-7 Annex C reference connectors:

This distinction is important for both purchasing and page SEO. Customers searching for a Male Plug Gauge usually need a dimensional inspection tool, not a complete test system.

What This Male Plug Gauge Checks

The Male Plug Gauge is used to check female Luer connector samples. The working end of the gauge provides a controlled male plug / Luer taper interface. During inspection, the male plug gauge is inserted into or mated with the female Luer connector to evaluate whether the internal taper and mating condition are suitable.

Typical verification purposes include:

• Checking the internal Luer taper of a female Luer connector
• Confirming basic mating fit before further functional testing
• Supporting incoming inspection of female Luer connector components
• Helping R&D teams compare connector samples during design verification
• Supporting factory QC checks for production batches

This gauge does not replace a complete leakage tester, axial load tester, stress cracking setup or resistance-to-overriding test fixture.

How It Is Used

Typical Use Procedure

1. Confirm that the sample is a female Luer connector.
2. Clean the sample and the Male Plug Gauge working interface before inspection.
3. Insert or mate the male plug gauge with the female Luer connector according to the internal inspection procedure.
4. Observe whether the connector fits the gauge as expected.
5. Record the inspection result according to the laboratory or factory QC requirement.
6. After inspection, clean the gauge and store it in a protective case.

Important Use Note

The Male Plug Gauge should be used only for dimensional or fit verification. If the customer needs leakage, sub-atmospheric pressure air leakage, axial load separation, unscrewing separation, stress cracking or resistance-to-overriding testing, the appropriate ISO 80369-20 test apparatus and ISO 80369-7 Annex C reference connector should be selected according to the test method.

Operation and Handling Notes

The Male Plug Gauge is a precision inspection tool and should be handled carefully.

• Confirm the sample is a female Luer connector before use.
• Do not use this gauge as a leakage tester or force test fixture.
