Luer Fittings And Connectors
Colour Coded Luer Connectors
Colour coded luer connectors and tee pieces used where a line has to be identified at a glance.
Product Overview
What This Component Is
Colour coded luer connectors and tee pieces used where a line has to be identified at a glance. Colour on a medical fitting is not decoration, it is a safety instruction, so the colourant and the resin are locked before the first sampling run.
Key Benefits
- Colour standard applied once, on our own tools, across the whole family
- Tee and straight geometry molded in the same plant on the same standard
- Colourant confirmed in writing before sampling rather than adjusted mid run
Molded on tooling we cut ourselves in Shenzhen. Certification covers the site doing the work: ISO 9001:2015 and ISO 13485:2016.
Who It Is For
- Infusion set assemblers
- Multi line device makers
- Brands with a colour coding standard to protect
Problems It Solves
- Colour drifting between lots so two shipments do not match on the shelf
- Tee junctions that leak at the branch under pressure
- Colour matching handled by the molder's judgement rather than a standard
Application Scenarios
- Line identification on multi lumen sets
- Tee junctions in infusion circuits
- Colour coded sampling ports
Technical Features
How It Is Engineered
- Branch geometry cored so the wall section stays even through the tee
- Masterbatch dosing controlled through the molding cell
- Colour reference retained against the tool record in our ERP system
Materials
- Medical grade resin selected against your specification rather than substituted by us
- Customer nominated grades accepted where a device master record already fixes the material
- Colourants and additives confirmed in writing before the first sampling run

Figures above are plant and tooling capabilities recorded on our own site. Part level tolerances are confirmed against your drawing at mold flow review rather than quoted as a blanket number.
Manufacturing Process
- Mold design review
- Steel machining and EDM
- Mold trial and cavity sampling
- Clean room or conventional molding
- In process dimensional check
- Clean room packing
Quality Control
- Cavity by cavity dimensional sampling before a tool is released
- In process checks during the molding run rather than only at the end
- ERP system records the lot, tool and machine behind every shipment
Customization Options
- Cavitation sized to your annual forecast instead of a fixed standard tool
- Colour and resin grade to your specification
- Clean room packing format and labelling agreed before the first shipment
Comparison
Compared With Other Routes
| Painting or marking after molding | Moulded in colour cannot rub off in transit or in use, which is the whole point of a safety colour code. |
|---|---|
| Letting each molder match colour locally | Every local match is a new drift. One plant holding the family holds one reference. |
Use Guide
How To Handle It
- Supply the colour standard with the enquiry, not after the tool is cut
- Check branch seal under pressure during qualification
- Store away from sunlight, which fades pigments over long shelf lives
Questions Buyers Ask
Questions About Colour Coded Luer Connectors
How do you control colour between lots?
The colourant is fixed in writing before sampling and the reference is held against the tool record, so a repeat order is matched to the original rather than to the last run.
Can you mold a tee and a straight connector on one tool?
Family tooling is possible where the shot weights are compatible. We review this at quotation and tell you if separate tools would give a better part.
Do you support a colour coding standard we already publish?
Yes. Send the standard with the enquiry and we work to it rather than to our own interpretation.
