High-Performance PU Spiral Hose: Durable, Flexible Conveyance Solutions
In demanding industrial environments, reliable material and air conveyance is non-negotiable. Our professional-grade PU spiral hose is engineered to meet this challenge head-on. Combining exceptional abrasion resistance with outstanding flexibility, this hose is the go-to solution for a wide range of suction and pressure applications. Designed for longevity and performance, it ensures efficient operations while minimizing downtime and replacement costs, making it an indispensable component for modern industry.
1. Product Overview
Our PU spiral hose is constructed from high-grade, thermoplastic polyurethane (TPU), reinforced with a rigid, embedded steel or plastic spiral. This innovative design creates a robust yet highly flexible conduit perfect for moving abrasive materials, granules, chips, and air. Unlike standard PVC or rubber hoses, the PU construction offers superior resistance to wear, oils, and weathering, ensuring a longer service life even in the most punishing conditions. It is the ideal choice for industries seeking a balance between durability, flexibility, and cost-effectiveness in their conveyance systems.
2. Key Features
- Exceptional Abrasion Resistance: The tough PU outer layer withstands constant scraping and impact from sharp or coarse materials, far outperforming standard PVC hoses.
- High Flexibility & Springback: The integrated spiral provides structure while allowing the hose to bend and twist without kinking, collapsing, or permanently deforming.
- Lightweight & Easy to Handle: Significantly lighter than rubber hoses with similar durability, reducing operator fatigue and simplifying installation.
- Anti-Static & Food-Grade Options: Available in specialized versions to prevent static discharge in dusty environments or meet FDA/EC standards for food and pharmaceutical handling.
- Excellent Weather & Chemical Resistance: Resists degradation from sunlight (UV), ozone, moisture, and many oils and chemicals, suitable for indoor and outdoor use.
- Smooth Bore: The smooth inner surface minimizes flow resistance and prevents material buildup, ensuring consistent and efficient conveyance.

5. Advantages Over Alternatives
Choosing the right hose impacts operational efficiency and total cost of ownership. Our PU spiral hose offers distinct benefits:
- vs. PVC Spiral Hose: 5-10x greater abrasion resistance, better flexibility in cold conditions, and superior resistance to oils and chemicals.
- vs. Rubber Hose: Lighter weight (easier handling), better flexibility, more resistant to weathering and ozone cracking, and typically more cost-effective.
- vs. Non-Reinforced Hose: The embedded spiral prevents collapse under suction and maintains an open bore during bending, ensuring consistent flow rates.
- Total Cost Savings: Longer lifespan reduces frequency of replacement. Lower weight cuts shipping costs and improves ergonomics. Reduced downtime for maintenance boosts overall productivity.

7. Frequently Asked Questions (FAQ)
Q1: Can your PU spiral hose be used for both suction and blow applications?
A: Absolutely. The rigid spiral reinforcement prevents the hose from collapsing under vacuum (suction) and also contains positive pressure for blowing applications, making it a true dual-purpose hose.
Q2: How does it perform in cold warehouse environments?
A: Our PU material retains excellent flexibility down to -40°C, unlike standard PVC which becomes stiff and brittle. This ensures it remains workable and crack-resistant in cold storage or outdoor winter conditions.
Q3: Is it suitable for food contact?
A: We offer specific food-grade and anti-microbial versions of our PU spiral hose that are compliant with FDA and EU regulations. Please specify this requirement when inquiring.
Q4: How do I determine the correct diameter for my application?
A: The ideal diameter depends on the material being conveyed, flow rate, and the power of your suction/pressure system. As a general rule, a larger diameter reduces air velocity and wear for abrasive materials. Our technical team can assist you with sizing recommendations.
Q5: What are the available connection options?
A: Hoses can be supplied cut to length with plain ends, or fitted with a wide variety of standard or custom couplings (e.g., camlock, flange, clamp, quick-release). We can assemble these for you or provide the components for on-site fitting.
