Hot Tar & Asphalt Hose (150 PSI)
An asphalt hose (also called a hot tar hose or bitumen hose) is a specialized high-temperature rubber hose designed for transferring hot asphalt, tar, and bitumen at continuous temperatures up to 180°C (356°F). Unlike standard High Pressure Hose or Wire Braided Hose, this asphalt hose is engineered to resist thermal aging, vacuum collapse, and static buildup. As a professional asphalt hose manufacturer and china-based factory, we supply this hose according to international standard EN 1765. This definition makes it the correct solution for road construction, asphalt plants, and tanker trucks where general-purpose hoses fail.
Summary for engineers: An asphalt hose is a high-temperature, steel wire reinforced rubber hose used for transferring hot asphalt, bitumen, and tar in industrial applications. It is designed for both suction and discharge, with anti-static protection, full vacuum capability, and temperature resistance up to 180°C.
Key Features of This Asphalt Hose
Why is this bitumen hose superior to standard rubber hoses? It offers five critical advantages for hot asphalt transfer:
- Extreme Temperature Stability: Operates continuously from -40°C to +180°C without hardening or cracking.
- Full Suction Capability: Embedded steel wire helix prevents kinking or collapse under vacuum, making it a true asphalt suction hose.
- Anti-Static Safety: Embedded wires dissipate static charge during high-flow transfer, a critical safety feature.
- High Abrasion Cover: The synthetic elastomer cover resists ozone, weather, and job site abrasion.
- Complete Assembly Support: Available as a bare hose or finished hose assembly with crimped fittings, reusable fittings, adapters, flanges, protective sleeves, and guards.

Structure & Materials (Why This Asphalt Hose Works)
- Tube: Black, smooth, special elastomer compound. Resists hot bitumen and tar without swelling or degrading.
- Reinforcement: 2 or 4 layers high tensile cord + steel wire helix + anti-static wires.
- Cover: Black, wrapped finish, synthetic elastomer. High abrasion, ozone & weather resistance.
Asphalt Hose Applications (Where This Asphalt Hose Is Used)
This bitumen transfer hose is the standard choice for:
- Asphalt Tanker Loading/Unloading: Suction and discharge lines for tanker trucks (ideal asphalt hose for tanker truck).
- Bitumen Storage Tank Transfer: Connecting storage to processing units.
- Asphalt Spray Truck Systems: Feeds for spray bars on paving machines.
- Roofing Kettles: Hot tar supply for built-up roof (BUR) applicators.
- Hot Mix Asphalt Plants: Transfer between storage, mixers, and load-out bays.
Asphalt Hose vs. Oil Hose (Comparison Guide)
A common search is: Why does standard oil hose fail in asphalt applications? Here is the direct comparison.
| Feature | Asphalt Hose (150 PSI) | Standard Oil Suction Hose |
|---|---|---|
| Max Continuous Temp | 180°C (356°F) | 100°C (212°F) |
| Cover Material | Heat-aged, ozone-resistant compound | Standard NBR/PVC (hardens rapidly) |
| Vacuum Rating | Full vacuum (steel wire helix) | Limited (fabric reinforcement) |
| Static Protection | Mandatory anti-static wire | Optional or absent |
| Service Life in Asphalt | 12-24 months | 1-4 weeks (cracking/blowout) |
How to Choose the Right Asphalt Hose (Buyer’s Guide)
When you buy an asphalt hose, consider these three factors:
- Temperature: Verify the hose matches your maximum operating temperature (our asphalt hose: -40°C to +180°C).
- Pressure & Vacuum: For asphalt suction hose duty, ensure a steel wire helix is present.
- Fittings & Assembly: For maximum reliability, order a factory-crimped hose assembly. We provide crimped fittings, reusable fittings, adapters, and flanges to match your camlock or threaded connections.

FAQ
Q: What temperature can an asphalt hose handle?
A: A high-quality asphalt hose can handle continuous temperatures up to 180°C (356°F), with specialized rubber compounds designed to resist thermal aging and maintain flexibility.
Q: What hose is best for hot asphalt transfer?
A: The best hose for hot asphalt transfer is a steel wire reinforced asphalt hose with anti-static properties and a temperature rating of at least 180°C, designed for both suction and discharge. Our Hot Tar & Asphalt Hose 150PSI meets exactly this specification.
Q: Can I use a standard hydraulic hose for hot bitumen?
A: No. Standard Wire Spiral Hose or wire braided hydraulic hose for hydraulics uses a tube compound not rated for 180°C asphalt. It will swell, blister, and fail quickly.
Q: Why does my asphalt hose keep cracking?
A: Cracking indicates either a cover not rated for high temperature or ozone attack. Our asphalt hose cover is specifically compounded for hot asphalt and weather resistance. Using protective sleeves on high-friction areas further extends life.
Q: How do I buy asphalt hose in bulk?
A: As a direct asphalt hose manufacturer, we support bulk and wholesale orders. Contact us for asphalt hose price and OEM ODM branding options.
