LIGHT, FLEXIBLE PVC HARD SUCTION HOSE FOR DRAFTING
Accept no substitutes: Maxi-Flex is the original lightweight PVC suction-only hose. Simply built smarter, its special corrugated PVC exterior provides maximum flexibility and a smooth waterway for superior flow. Clear flexible PVC between the helix ribs allows full view of water, while distinctive black helix ribs deliver maximum UV protection. Lightweight and ultra-flexible, Maxi-Flex hose affords one person hookup operation with extruded aluminum re-attachable, bolt-on couplings. Designed for suction only—purpose-built for full vacuum; drafting any rural or municipal non-pressurized water source.
- High-Performance. Corrugated PVC exterior provides durability, but with lightweight portability.
- Flexible. Easy to transport and more flexible than traditional hard suction hoses for fast, one person hookup.
- Innovative: Clear flexible PVC in between helix provides full vision of water flow; black helix ribs provide UV protection. Limit exposure to direct sunlight for extended periods of time.
- Dependable. One piece extruded aluminum field repairable, re-attachable collars; no plastic parts—and folding handles available.
- Efficient. Designed for suction only. Suitable for hard suction applications, drafting from rural water sources.
- Versatile. Available 1½”, 2½” and 3″ expansion ring couplings. 4″, 4½” 5″, and 6″ coupled with retractable bolt-on couplings.
