Radiator Rubber Hose 1300-613030A Meshed Polyester Cord Reinforced Water Hose for Truck

The Jingyi Radiator Rubber Hose (part number 1300-613030A) is a replacement component for the engine cooling systems of heavy trucks, buses and semi-trailers. It is built to original equipment specification from quality materials, so it installs on the original mounting points and performs reliably throughout the service life of the vehicle. Key ratings include Temperature Range ‑40°C～134°C. Resists coolant corrosion, anti‑hardening and zero leakage in long‑term operation.

A natural rubber base reinforced by multi-layer mesh polyester cords gives this radiator hose its strength: it resists coolant corrosion and ageing, stays supple in cold weather and does not harden in service. The mesh cord structure stops the hose collapsing under negative pressure and soaks up water-pressure pulses, cutting the risk of bursting while keeping a tight, leak-free seal.

Every unit is manufactured to original equipment specification and inspected before it leaves the factory, so it matches the fit, function and durability of the original part. Sealed, vibration-tested construction keeps performance stable in the heat, dust, road salt and constant vibration found on commercial vehicles, and standard interfaces make installation and maintenance straightforward. Spare parts, technical data and fitting advice are available on request.

• Natural Rubber Base Material: Made from a natural rubber base compound that resists coolant corrosion and ageing for a long, leak-free service life.
• Multi Layer Mesh Polyester Cord: Reinforced with multi-layer mesh polyester cords that add strength and stop the hose collapsing under negative pressure.
• Coolant and Anti Aging Resistant: Withstands coolant attack and hardening, so the hose stays supple and keeps its sealing performance over time.
• Wide Temperature Range: Rated from -40°C to 125°C for reliable service in both winter cold and hot engine bays.
• Zero Leakage Seal: Moulded to the original shape for a tight, leak-free fit on the radiator and engine connections.
• Custom Shaped Elbows Available: Special-shaped elbows can be produced to match OE numbers for a wide range of Chinese and European heavy-duty trucks.

The hose is used on the engine cooling systems of Chinese and European heavy-duty trucks, including Weichai, Sinotruk HOWO, Dongfeng and other mainstream power units. Custom special-shaped elbows are available to match OE numbers, and it is the correct replacement for a swollen, cracked or leaking original coolant hose.
