Coolant Hoses - Engine Room Consumables and Spares
Marine coolant hoses are flexible reinforced hoses used to circulate engine coolant between the engine, heat exchanger, expansion tank, pumps, and other cooling-system components. They are commonly supplied in EPDM rubber or silicone constructions and selected by temperature, pressure, diameter, and coolant compatibility.
ProShipWorks provides end-to-end support to source and supply Coolant Hoses for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Commonly specified to SAE J20 and ISO 4081 for engine cooling-system hoses. Product-specific compliance, temperature ratings, pressure ratings, and chemical compatibility must be verified from the manufacturer datasheet. |
|---|---|
| Class Approval | Coolant hoses are not universally class-approved. Type approval or project acceptance may be available from DNV, ABS, Lloyd's Register, Bureau Veritas, or ClassNK when specifically certified and installed according to the approved application. |
Installation, Maintenance & Safety Information
| Installation Notes | Confirm inside diameter, hose routing, bend radius, temperature, pressure, and coolant compatibility before installation. Use marine-grade clamps, keep the hose clear of hot surfaces and moving parts, avoid twisting, and do not exceed the manufacturer's minimum bend radius. |
|---|---|
| Maintenance Tips | Inspect during routine engine-room rounds for swelling, softening, cracking, abrasion, leaks, and clamp corrosion. Check clamps and connections after thermal cycling. Replace hoses showing deterioration or according to the vessel's planned-maintenance schedule. |
| Safety Notes | Isolate and cool the system before removal because coolant may be hot and pressurized. Drain and contain coolant safely, use suitable gloves and eye protection, and never substitute a coolant hose with a fuel, hydraulic, or general-purpose hose. |
