- 2 structures: mono or double
- 5 types of packaging: 1, 5, 10, 50 o 100 mt.
- resists embrittlement, remains flexible
- inner tube stands up to unleaded fuels
- outer purple tube protects from UV rays, high engine temperature and mechanical stress translucent, so dirty fuel is visible through pipe
- double-skinned pipe, resists embrittlement, remains flexible
- inner tube stands up to E10 fuel
- outer tube protects from high engine temperature and mechanical stress
- Polarlys material stands up to unleaded fuels
- economic series
- flexible pvc
- poor resistance to gasoline
- over time they tend to become "stiff"
- poor resistance to abrasion and cold
