Enteral / Nutrition
Enteral Feeding Connector
Enteral feeding connectors are governed by ISO 80369-3 (ENFit) to prevent dangerous misconnection with IV luers. The material set needs tight dimensional control at the connector, lipid and nutrition-formula resistance, and soft, kink-resistant tubing for prolonged contact.

Component material package
A recommended grade per component, drawn from the Nexeo catalog. Recommendations are engineering assessments; a cited property links the choice to data we hold for that grade.
| Component | Recommended grade | Why |
|---|---|---|
ENFit connector Misconnection-proof rigid fitting | Purell RP374R Polypropylene (PP) | A random-copolymer PP holds the ISO 80369-3 thread geometry and resists the lipids in enteral formula. |
Feeding tube Soft prolonged-contact conduit | Tecoflex EG-80A Thermoplastic Polyurethane (TPU) | An aliphatic TPU gives soft, kink-resistant, non-yellowing tubing suited to prolonged enteral contact. |
Strain-relief boot Flexible connector-to-tube transition | THERMOLAST M TM5MED Thermoplastic Elastomer (TPE) | A medical TPE overmolds the connector-to-tube junction for strain relief without adhesives. |

Key regulatory requirements
- ISO 80369-3 (ENFit) enteral connectors
- ISO 10993-1 prolonged contact
- DEHP-free / non-PVC increasingly specified for enteral
Engineering watch-outs
- ENFit geometry is tightly toleranced — qualify the connector grade for dimensional stability and shrink.
- Lipid resistance matters: enteral formulas are fat-rich and can swell some elastomers.
- Aliphatic vs aromatic TPU affects yellowing; confirm the grade family against the color requirement.
