The Joint Sealing Hose from Jingcheng is a specialized high-temperature, low-pressure heated hose engineered specifically for pavement maintenance equipment and crack sealing machinery. With our proprietary inner tube reinforcement technology, this product delivers exceptional durability under harsh field conditions, significantly extending service life and reducing operational costs.
Our sealing hoses maintain optimal heating performance even in demanding environments—whether under intense summer sun or cold, wet winter conditions. The heating element is uniformly woven to ensure consistent temperature distribution, allowing sealant materials to flow smoothly and maintain quality throughout the entire application process.
The common failure point in standard sealing hoses is inner tube collapse under repeated high-temperature, high-pressure cycles. Jingcheng's exclusive reinforcement technique eliminates this industry-wide problem by maintaining inner tube integrity even at 230°C, dramatically extending hose lifespan and reducing downtime on job sites.
Since 2013, Jingcheng has partnered with leading pavement maintenance contractors. Our sealing hoses are proven to outperform competitors in:
Extreme temperature fluctuations
High-dust construction sites
Continuous high-temperature operation
Heavy vibration from equipment
Customer feedback consistently highlights exceptional stability and durability.
The heating element is uniformly woven throughout, minimizing temperature variation across the inner wall. This ensures sealant reaches the application point at the correct viscosity, improving joint quality and reducing material waste.
We utilize premium insulation materials with superior heat retention efficiency, reducing thermal loss and lowering electricity consumption during operation.

Every Jingcheng heating hose undergoes triple quality verification:
Third-party testing laboratory (routine inspection)
In-house quality control
Supplier verification
We maintain full traceability for every production batch, ensuring consistency and reliability on your jobsite.
Q: Why does sealing equipment require heated hoses?
A: Sealant materials (modified asphalt, polyurethane) are extremely viscous at room temperature. Continuous heating maintains the material at optimal viscosity from the storage tank through the application nozzle, ensuring quality joints and minimizing material loss.
Q: How does inner tube reinforcement extend hose life?
A: Standard sealing hoses suffer inner tube collapse under repeated high-temperature cycles, leading to reduced flow or blockage. Jingcheng's reinforcement technology maintains inner tube geometry even at 230°C, preventing collapse and dramatically extending service intervals.
Q: Can I upgrade the maximum temperature beyond 230°C?
A: Our standard specification is 230°C. For higher-temperature applications, contact our engineering team for a custom solution.
Q: Will it fit my existing equipment?
A: Our hoses support SAE, NPT, and ISO connector standards, compatible with virtually all major sealing equipment brands. Provide your equipment model or connector images, and our team will confirm compatibility before production.
Q: What if I need a different hose length or configuration?
A: We customize every dimension—length, connector type, voltage, sensor type, and power output. Our standard lead time for custom orders is 7–14 business days.
