Gear Oils - Hose Couplings and Petroleum Products
Marine gear oils lubricate reduction gears, thrusters, winches, and other enclosed shipboard gearboxes. Marine hose couplings connect petroleum-product transfer hoses and are selected for the hose construction, fluid compatibility, pressure, temperature, and classification requirements.
ProShipWorks provides end-to-end support to source and supply Gear Oils 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 | Gear oils should meet the applicable gearbox manufacturer specification and may reference API GL-4 or GL-5 where permitted by the OEM. Petroleum hose couplings may be manufactured to EN 14420 series requirements; hose assemblies should comply with the applicable hose and pressure standards. |
|---|---|
| Class Approval | Approval requirements depend on the vessel application and class rules. DNV, ABS, Lloyd's Register, Bureau Veritas, and ClassNK may require documentation or type approval for marine hose assemblies, fuel transfer systems, or safety-critical installations. |
Installation, Maintenance & Safety Information
| Installation Notes | Verify lubricant grade, additive compatibility, fill volume, and OEM requirements before use. For couplings, confirm hose bore, pressure rating, temperature range, petroleum compatibility, gasket material, locking arrangement, and correct assembly procedure. Pressure-test hose assemblies before service. |
|---|---|
| Maintenance Tips | Check gear-oil level, condition, water contamination, viscosity, and metal particles at scheduled intervals. Inspect couplings, seals, threads, locking devices, and hose covers for wear, corrosion, leakage, or deformation. Replace damaged seals and hose assemblies and maintain clean protective caps. |
| Safety Notes | Use the correct lubricant and coupling rating; never mix incompatible oils or materials. Isolate, depressurize, drain, and electrically bond or ground petroleum transfer equipment where required before disconnection. Control ignition sources, provide ventilation, wear chemical-resistant PPE, and follow the vessel's spill and fire procedures. |
