Fuel Oil Hose Wrapped Surface 300 PSI
Model Series: FW300 (Fuel Oil Hose Wrapped Surface – Industrial Code)
A suction discharge hose engineered for demanding water transfer and dewatering applications. This 300 PSI suction discharge hose prevents collapse under full vacuum while maintaining flexibility for construction, agricultural, and industrial pumping systems. As a direct manufacturer and supplier in china, we provide a complete solution for engineers and procurement teams.
What Is a Suction Discharge Hose?
A suction discharge hose is a reinforced industrial rubber hose designed to both draw (suction) and transport (discharge) water, slurry, or non-corrosive fluids. Unlike a standard discharge hose (pressure only), a true suction hose includes a steel helix wire to prevent collapse under vacuum conditions. The FW300 series meets this definition, functioning as both a suction hose for water pump inlets and a high pressure hose for discharge lines up to 300 PSI.
What Is a Suction Discharge Hose Used For?
A suction discharge hose is used for transferring water, slurry, and non-corrosive fluids in construction, agriculture, and industrial pumping systems. It is commonly connected to water pumps for dewatering, irrigation, and general fluid transfer. This industrial suction hose is the standard choice for jobsites requiring both vacuum resistance and pressure capability.

Suction Discharge Hose vs. Standard Water Hose: Comparison
| Feature | FW300 Suction Discharge Hose | Standard PVC/Water Hose |
|---|---|---|
| Helix Wire | Yes (prevents collapse) | No |
| Vacuum Rating | Full vacuum resistant | Not rated (collapses) |
| Pressure Rating | 300 PSI | 150-200 PSI typical |
| Cold Flexibility | -30°C | 0°C (becomes stiff) |
| Abrasion Resistance | High (SBR cloth cover) | Low (smooth PVC) |
| Typical Application | Pump inlet + outlet | Gravity flow only |
Application Industries & Use Cases
This heavy duty suction discharge hose is specified by civil contractors, municipal teams, plant engineers, and agricultural operators.
- Construction: Dewatering excavations, slurry transfer, temporary bypass lines.

Frequently Asked Questions (FAQ)
Q: What is a suction discharge hose used for?
A: A suction discharge hose is used for transferring water, slurry, and non-corrosive fluids in construction, agriculture, and industrial pumping systems. It is commonly connected to water pumps for dewatering, irrigation, and fluid transfer.
Q: Can this suction discharge hose be used for fuel or oil?
A: No. Despite the industrial code “Fuel Oil Hose,” the FW300 series is engineered specifically for water and non-corrosive fluids. Request our dedicated fuel hose series for petroleum products.
Q: What is the difference between a suction hose and a discharge hose?
A: A suction hose contains a helix steel wire to prevent collapse under vacuum. A standard discharge hose has no wire and will collapse on pump inlets. The FW300 handles both roles.
Q: How do I choose the correct suction hose diameter?
A: Match the hose ID to your pump port size. For a 2″ pump port, use FW300-32 (2″ ID). Undersizing causes cavitation.
Q: Do you offer bulk pricing for wholesalers and distributors?
A: Yes. As a direct factory, wholesaler, and exporter, we provide tiered price lists for bulk and wholesale orders. Contact us for discount schedules.
Q: Can you provide pre-assembled hoses with crimped fittings?
A: Yes. We offer complete hose assembly with crimped fittings, reusable fittings, adapters, and flanges. Send your specification for a quote.
How to Choose the Right Suction Discharge Hose
- Diameter: Match your pump or equipment port size (1/4″ to 2″ available).
- Pressure: Confirm system pressure ≤ 300 PSI.
- Vacuum: Does the hose see pump inlet vacuum? → Requires helix wire (FW300 has it).
- Environment: Outdoor/abrasive conditions? → SBR cloth-impression cover (standard).
- Length: Standard 100M coils or custom hose assembly lengths.
