Product Overview
The Black Hose For Water is designed for industrial water suction and discharge applications in agriculture, construction, irrigation, and general fluid transfer.
It is manufactured using high-grade PVC compound with a spiral steel wire reinforcement embedded in the hose wall, which provides structural stability under vacuum and pressure conditions. The design helps maintain round shape during operation and reduces the risk of collapse or flow interruption.

Key Features
- Integrated with a high-tensile spring steel wire reinforcement to prevent collapsing, flattening, or cross-section deformation under full vacuum suction and negative pump pressure.
- Formulated exclusively with premium virgin PVC resin to ensure superior wall shear strength, exceptional aging resistance, and an extended operational lifespan that lowers the Total Cost of Ownership (TCO).
- Enhanced with industrial-grade anti-UV additives and premium plasticizers to maintain excellent flexibility from -10°C to +60°C without cracking, hardening, or degrading under direct sunlight.
- Engineered with a precisely calculated steel wire pitch to achieve a tight bending radius (down to 4x ID for standard sizes) without kinking or restricting fluid velocity.
- Produced via computerized automatic extrusion lines to guarantee consistent wall thickness and precise concentric centering of the steel wire, ensuring maximum safety margins under peak burst pressures.
Customization & OEM Capabilities
Branding & Marking: Continuous high-resolution ink-jet printing of your custom brand logo, part numbers, specification data, and sequential meter counters every meter.
Color Customization: Base Model Color: Solid Industrial Black. Available with transparent, industrial blue, dark green, or specialized anti-static colored walls to match your specific market preferences.
Custom Material Formulations: Optional FDA-compliant food-grade compounds (compliant with FDA 21 CFR 175.300) or high-chemical-resistance variants are available upon request.
Applications
Agriculture & Irrigation
High-volume water transfer, liquid fertilizer discharge, agricultural pump connections, and overhead irrigation lines.
Construction & Mining
Heavy-duty dewatering of excavation sites, trench water removal, quarry drainage, and sediment control.
Industrial Manufacturing
Factory central vacuum lines, industrial fluid transfer, chemical-rinse lines, and machinery cooling water conveyance systems.
Municipal Engineering
Emergency flood control drainage, sewer bypass lines, and municipal wastewater management.
Manufacturing & Quality Control
Every production batch undergoes a continuous extrusion process integrated with synchronized steel wire forming machinery, strictly governed by ISO 9001:2015 Quality Management Systems.
Quality control includes:
- Raw material inspection (PVC compound and steel wire tensile strength)
- Wall thickness monitoring during extrusion
- Steel wire positioning verification
- Vacuum resistance testing
- Hydrostatic pressure testing
- Visual inspection for structural uniformity
These processes are implemented to maintain consistent performance across production batches and reduce variation in mechanical strength.

FAQ
Q: Do you use recycled materials in this hose?
A: No. We use 100% virgin PVC and high-tensile spring steel wire. This keeps the hose walls strong, extends service life, and meets RoHS and REACH standards for international markets.
Q: Will this hose collapse under heavy suction or burst at high pressure?
A: The integrated high-tensile spring steel wire reinforcement keeps the hose perfectly round and structurally stable under working vacuum ratings (ranging from -0.80 Bar up to -0.95 Bar based on individual model specifications) at room temperature (+20°C). Note: For applications involving continuous hot fluids or ambient temperatures approaching +60°C, please consult our engineering team to adjust specialized PVC wall formulations.
Q: What is your standard delivery time and monthly factory output?
A: Our factory produces 500,000 meters per month. A standard 20ft container order takes 15 to 20 days to ship from factory gate.
Q: Do you offer free samples and OEM/private labeling?
A: Yes. We provide free 0.5-meter samples for your laboratory testing. We also support full OEM customization, including custom meter-marking branding, specific coil lengths, and seaworthy pallet packaging.
Q: How does the hose perform in heavy-duty construction dewatering with gravel and mud?
A: While the premium virgin PVC thick wall provides excellent internal smooth flow and shear strength against sediment wear, for high-abrasive slurries containing large sharp rocks, please contact our engineers. We can customize a higher-density PVC compound to further extend the wear life.
