Fluid Handling
Fuel-System Connector & Clip
A fuel-line connector must retain seal geometry and pull-off strength while exposed to fuel blends, heat, vibration, assembly damage, and permeation requirements. The connector body, retainer, and seal are a qualified system; changing one material can alter stress, swelling, and insertion force everywhere else.

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 |
|---|---|---|
Protective line sleeve Guards the line against abrasion and stone impact | Elastollan 1185A Thermoplastic Polyurethane (TPU) | An abrasion-resistant TPU candidate suits a flexible protective sleeve after fuel splash and hydrolysis screening. |

Validation & compliance path
- SAE J2044 where applicable to liquid-fuel quick connectors
- Regional evaporative-emissions and permeation requirements
- OEM fuel-blend, pressure-cycle, pull-off, and thermal-aging specification
Engineering watch-outs
- Fuel blends evolve; qualify the exact regional fuels and aged-fluid conditions.
- Moisture-conditioned polyamide dimensions can change seal squeeze and insertion force.
- POM and strong acids are incompatible; assess every cleaner and process chemical.
