Gauges for Anaesthetic and Respiratory Equipment – Conical Connectors as per ISO5356-1:2004
Gauges for Anaesthetic and Respiratory Equipment – Conical Connectors as per ISO5356-1:2004
- Model： ISO5356
The anaesthetic and respiratory equipment – conical connectors are cones & sockets made of metal & non-metal; intended for connecting the lines. Cones & Socket engaged in between each other by applying push force with twistaction.
Our gauges are designed and manufactured according to ISO5356-1:2004 for testing the anaesthetic & respiratory equipment’ssuch as Endotracheal Tube, Tracheostomy Tube, Flexible Catheter Mount, Nebulizer Mask, Venturi Valve Mask Kit, Oxygen Recovery T-kit, Ventilator Tubing, Airway Connectors, Bacterial Filters, Respiratory Gas Humidifiers & certain other breathing system equipment’s.
Our plug and ring gauges are use to check conical connectors made of metal &materials other than metal.

Gauges for Anaesthetic and Respiratory Equipment – Conical Connectors as per ISO5356-1:2004. ISO 5356-1 — Anaesthetic and respiratory equipment — conical connectors — Part 1: cones and sockets. It is the reference conical side of the interface. Kingpo machines reference connectors and gauges in-house from hardened steel, inspects them against the figure before despatch and supplies them with a calibration certificate.
What it is used for
- Dimensional and mechanical checks on the connector under test
- Repeatable mating with the sample so results are comparable between laboratories
ISO 5356-1 specifies the dimensional and gauging requirements for the 8.5 mm, 15 mm, 22 mm, 30 mm and 32 mm cones and sockets used to connect breathing systems, anaesthetic gas scavenging systems and ventilators.
Specification
| Standard | ISO 5356-1 |
| Material | Hardened stainless / tool steel |
| Calibration | Calibration certificate supplied |
| Made by | Kingpo — machined, inspected and calibrated in-house |
How the test is run
- Condition the reference connector and the sample together at the test temperature stated in the standard.
- Mate the sample to the reference connector with the axial force or torque the standard specifies — never by hand feel alone.
- Apply the test medium. Leakage tests use liquid under positive pressure or air under sub-atmospheric pressure; mechanical tests use a tensile or compressive load at a controlled rate.
- Hold for the dwell time in the standard and record the reading.
- Repeat for the number of samples the protocol calls for and report the worst case, not the average.
Reference connectors are inspection tools. Overriding tests and repeated axial-load tests wear them by design — plan replacement against test cycles.
Choosing the right figure
Annex C (and the equivalent annexes in the other parts) assigns one figure per reference connector, and each figure is certified for a specific set of tests. Picking the wrong one is the most common specification error in this category: the connectors look almost identical, but a figure that is certified for leakage is not the one you use for separation from axial load. Order against the figure number in your test protocol, not against the photograph.
What this is not
A reference connector is not a complete test system. Leakage, sub-atmospheric air leakage and separation-force tests need pressure, vacuum or force applied through ISO 80369-20 test apparatus. It is also not a simple go/no-go dimensional gauge: for a quick fit check on a conical fitting you want a plug gauge or a ring gauge, not a reference connector.
Frequently asked questions
Can I use one reference connector for several tests?
Only the tests the figure is certified for. Different figures are machined to different limits and, in some cases, to different materials, because the test loads differ.
Do you supply the test apparatus as well?
Yes. Kingpo builds the ISO 80369-20 apparatus — leakage, sub-atmospheric air leakage, separation force and unscrewing torque — alongside the reference connectors.
Is a calibration certificate included?
Yes, and we re-calibrate reference connectors you already hold.
