Fuel Suction & Discharge Hose 300psi
Product Overview
The Fuel Suction & Discharge Hose 300psi is a high-performance rubber hose engineered for transferring water and non-corrosive fluids in demanding environments. As a definition of industrial reliability, this hose meets china and international standard requirements for heavy-duty service. It is the preferred solution for contractors and mine operators needing a dependable supply of bulk hose.
Constructed with a black smooth NR/SBR tube and a corrugated SBR cover, this Wire Spiral Hose offers exceptional vacuum resistance down to 0.8 bar and a working pressure of 20 bar (300 psi). Key advantages include excellent abrasion resistance, full vacuum rating, and flexibility from -32°C to +82°C. It solves the core pain points of frequent hose collapse, premature bursting, and fluid contamination in jobsite dewatering, mine drainage, and industrial fluid transfer.
Ideal for construction companies, mining operators, and heavy industry facilities, this High Pressure Hose ensures reliable suction and discharge. Backed by rigorous factory testing and quality assurance, it delivers a source you can trust. Whether you need to buy bulk rolls or custom lengths, this Fuel Suction & Discharge Hose 300psi is your most cost-effective solution.

Structure and Materials
- Tube: Black smooth NR/SBR rubber compound. Non-corrosive, resistant to water and mild chemicals.
- Reinforcement: Multi-plies of high-strength synthetic fiber with helix steel wire. This Wire Braided Hose construction provides excellent kink resistance and vacuum retention. Unlike simple Wire Braided Hose designs, the helix wire adds collapse resistance under suction.
- Cover: Black corrugated or wrapped cloth impression SBR rubber. Highly resistant to abrasion, ozone, and weather.
Why Helix Steel Wire Reinforcement?
The helix steel wire acts as a rigid to prevent the hose from collapsing under full vacuum (0.8 bar). In standard Wire Braided Hose without helix wire, suction can flatten the tube. Our engineering solution uses a helix angle optimized to balance flexibility with crush resistance.
Safety Factor & Pulse Data
- Safety Standard: 4:1 design factor (burst = 4 x working pressure) per international standard.
- Pulse Test: Successfully passed 200,000 impulse cycles at 133% working pressure per ISO 6803.
- Vacuum Integrity: Maintains round cross-section at 0.8 bar full vacuum for 10,000 cycles.
Media Compatibility
| Fluid Type | Compatibility | Notes |
|---|---|---|
| Water (fresh/salty) | Excellent | Ideal for dewatering |
| Muddy water / Slurry | Good | Flush after use |
| Diesel / Fuel | Fair | Not for continuous fuel immersion |
| Mild chemicals | Consult factory | Limit temperature to 60°C |

Installation, Operation, and Maintenance Guide
- Handling: Do not drag over sharp edges. Use protective sleeves at abrasion points.
- Bend Radius: Minimum bend radius = 10 x OD. Avoid kinking near fittings.
- Suction Use: Keep hose fully immersed or use foot valve. Pre-wet to reduce initial suction resistance.
- Fitting Attachment: Use only crimped fittings or reusable fittings rated for helix wire hose. Standard Wire Braided Hose fittings may not seal properly.
- Storage: Store below +40°C away from ozone (motors, transformers). Use guards to protect end fittings.
- Inspection: Before each use, check cover for cuts exposing reinforcement. Replace immediately if helix wire visible.
