Excavator Heater Hose

When an excavator's cabin struggles to stay warm or develops coolant leaks, worn pipeline parts are usually the root cause. This paired hose assembly consists of one inlet line and one outlet line, tasked with transporting heated coolant from the engine to the cabin heater core. For operators working outdoors in cold climates, functional heating makes long shifts far more comfortable. Exposed to persistent high heat and constant vibration on construction sites, ordinary hoses will gradually crack, kink or degrade over time. Replacing them is a simple and practical way to fix such daily operational issues.

We designed this Excavator Heater Hose to match the dimensions and performance of original factory parts, specifically tailored for Komatsu PC200-7 and PC210-7 excavators. Every hose is cut and bent according to original factory measurements, so it fits the reserved installation positions perfectly. Users can finish the replacement work directly without extra cutting or modifying on site.

Sold as a complete set, the two matched hoses cover the full circulation path of the heating system, saving buyers the trouble of searching for separate accessories. We select high-quality EPDM rubber to produce the inner tube. This material works stably when carrying high-temperature coolant, and will not swell or crack even after long-term exposure to heat.

The corrugated outer layer is a practical design for narrow engine compartments. It prevents the hose from collapsing or blocking fluid flow even when bent at sharp angles. The outer rubber layer also stands up well against dust, mechanical vibration and long-term sun exposure, fully adapting to the tough working environment of construction sites. All production follows OEM manufacturing standards, ensuring the hoses connect with engine assemblies and heater cores just like the original components.

On construction sites, equipment maintainers often replace aging, cracked or leaky hoses during regular inspections. Timely replacement can effectively stop coolant loss and avoid engine overheating triggered by damaged pipelines. This set is also widely used for winter maintenance, keeping heating systems reliable for machines running in low-temperature regions.

We take great care in packaging to protect the products during transit. Each hose is wrapped individually to avoid deformation and surface scratches, then packed into solid export cartons. Most standard models can be shipped out within 3 to 7 working days. If you need hoses with custom lengths or special bending shapes, we can also arrange production as requested. We support multiple global shipping solutions, including sea freight, air freight and express delivery to meet different logistics needs.

Many customers have questions before placing orders, and we have sorted out the most common ones here:

What is included in one full set?Each package contains one inlet hose and one outlet hose. The paired combination can fully meet the needs of a complete heating pipeline replacement.

Does this product fit other excavator models?This Excavator Heater Hose is manufactured to fit Komatsu PC200-7 and PC210-7. If you own other types of construction machinery, you can send us photos and dimensional data of your original hoses. Our team will check the compatibility or customize products according to your requirements.

How long can these hoses serve on site?Under regular operating conditions, the hoses can work steadily for several years. The materials are specially selected to cope with high temperature, vibration and long-term contact with coolant, which are the most common working states for excavators.

Can users complete the installation by themselves?People who have basic understanding of vehicle coolant systems can handle the replacement independently. Please remember to wait until the engine cools down completely before starting work to prevent scalding. If you pursue higher installation precision, hiring an experienced maintenance worker is a better choice.

What should I do if the product cannot fit the equipment after delivery?If you run into fitting problems after receiving the goods, please contact us and share relevant photos in time. We will communicate with you actively and offer targeted solutions, such as adjusting orders or arranging replacements.
