Start by application
Which connector family is involved?
Respiratory, enteral, neuraxial, Luer or another ISO 80369 scope changes the Figure family and product path.
A practical path for choosing ISO 80369 reference connectors, Luer gauges, test equipment, fixtures, complete sets and RFQ inputs.

Start with what the buyer knows. The correct page may be a standard, Figure connector, gauge, equipment method, complete set or document request.
Respiratory, enteral, neuraxial, Luer or another ISO 80369 scope changes the Figure family and product path.
Use the standard part to narrow the application family, then continue to Figure products or ISO 80369-20 methods.
Reference connectors are selected by Figure, tested sample side and mating relationship. Gauges follow a different route.
Leakage, axial load, torque, stress cracking and assembly workflows require different equipment, fixtures and documents.
A gauge is not a reference connector, and a complete set is not just a category page. Choose the buying path before the product.
Prepare standard part, Figure or Annex, sample photos or drawings, test method, quantity, fixtures, documents and certificate needs.
Use reference connectors for functional test setups and gauges for fit or dimensional checking.
State whether the sample uses a push-fit slip interface or threaded lock relationship.
If multiple Figures, gauges or methods are involved, ask for a set or configuration review.
