Couplings - Hose Couplings and Petroleum Products

Marine hose couplings connect petroleum-product hoses to loading arms, manifolds, tanks, bunkering systems, and transfer equipment. Common arrangements include cam-and-groove, flanged, quick-connect, and dry-disconnect couplings selected for the fluid, pressure, temperature, and hazardous-area requirements.

ProShipWorks provides end-to-end support to source and supply Couplings 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 Applicable requirements may include EN 14420-7 for cam-and-groove couplings, EN 1765 for rubber hose assemblies for oil suction and discharge, API RP 1004 for bottom-loading connections, and manufacturer-specific pressure, material, and fire-safety approvals. Confirm the exact standard for the selected coupling and service.
Class Approval Marine class approval is product- and installation-specific. DNV, ABS, Lloyd's Register, Bureau Veritas, and ClassNK may accept or approve coupling assemblies when specified by the vessel design, hose assembly, or cargo-transfer system. Verify documentation with the manufacturer and attending class society.

Installation, Maintenance & Safety Information

Installation Notes Verify coupling size, pressure rating, fluid compatibility, temperature range, hose bore, and connection standard before installation. Use the correct gasket or seal, tighten threaded or flanged connections to manufacturer torque, and ensure the hose is properly supported without twisting or excessive bending.
Maintenance Tips Inspect couplings, locking arms, pins, seals, threads, valves, and safety devices before use. Check for leakage, corrosion, deformation, and difficult operation. Replace damaged seals and worn components with approved parts, and keep protective caps fitted when disconnected.
Safety Notes Depressurize, drain, and electrically bond or earth the transfer system before disconnecting. Use only couplings rated for the petroleum product and operating pressure. Control ignition sources, prevent spills, wear suitable PPE, and follow the vessel's bunkering procedures, SDS requirements, and applicable ISGOTT guidance.
