Hangzhou Bright Rubber Plastic Product Co., Ltd. is one of the leading manufacturers and suppliers of automotive rubber coolant hose in China. If you're going to buy automotive rubber coolant hose made in China, welcome to get more information from our factory. We also accept customized orders.
Material & Temperature Resistance
This coolant hose is manufactured from high-quality EPDM (Ethylene Propylene Diene Monomer) rubber, a material specifically chosen for its excellent resistance to high temperatures and coolant fluids. It can withstand continuous operating temperatures ranging from -40°C to +135°C, with short-term peaks up to 150°C. Unlike standard rubber hoses that may harden or crack over time, EPDM maintains its flexibility and sealing performance throughout the life of the vehicle. This ensures reliable coolant flow and prevents overheating, even under demanding driving conditions.
Structural Design & Molding Process
This hose features a complex, pre-formed bent shape that is custom-molded to fit specific engine compartments. The molding process allows the hose to be produced as a single, seamless piece, eliminating the risk of leaks at joints or connections. The hose is reinforced with a high-strength textile braid embedded within the rubber wall, which provides resistance to internal pressure and prevents collapsing under vacuum. The integrated metal fittings at both ends are crimped or clamped securely to the hose, ensuring a durable, leak-free connection.
Connection & Sealing Performance
The hose is equipped with metal quick-connect fittings, which allow for fast and secure installation without the need for traditional hose clamps. These fittings feature a locking mechanism that snaps into place, providing a tight, vibration-resistant seal. The O-ring or gasket inside the fitting ensures a leak-free connection even under high pressure and thermal cycling. This design simplifies assembly and disassembly, reducing maintenance time and costs. The hose is engineered to meet the specific fit and performance requirements of the target vehicle model.
Durability & Aging Resistance
The EPDM rubber compound used in this hose offers outstanding resistance to aging, ozone, and UV radiation. It does not harden, crack, or become brittle after prolonged exposure to heat, coolant, or environmental factors. The textile reinforcement adds strength and prevents the hose from bursting under pressure, while the metal fittings are corrosion-resistant. This combination of materials ensures a long service life with minimal maintenance. The hose is also resistant to electrochemical degradation, which is a common cause of failure in traditional cooling systems.
Application Scope
This custom rubber coolant hose is widely used in automotive engine cooling systems, including radiators, heaters, and thermostat housings. It is available for a wide range of vehicle models, including passenger cars, SUVs, trucks, and commercial vehicles. The hose can also be customized for industrial cooling systems, agricultural machinery, and marine engines. We offer custom molding services based on your 3D CAD data or samples, ensuring a perfect fit for your specific application. Available in various sizes, shapes, and rubber compounds.
