Rubber Docking Plugs - Shipyard and Dry Dock Equipment
Rubber docking plugs are removable elastomeric plugs used in shipyards and dry docks to seal openings such as drain holes, sounding pipes, sea chests, and tank or hull penetrations. They help prevent water ingress during docking, repair, inspection, and testing.
ProShipWorks provides end-to-end support to source and supply Rubber Docking Plugs 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 documentation to be confirmed for the requested product. |
|---|---|
| Class Approval | Approval is generally project- or application-specific rather than inherent to the plug. Where required, acceptance may involve the vessel's classification society or shipyard procedures, including DNV, ABS, Lloyd's Register, BV, or ClassNK. |
Installation, Maintenance & Safety Information
| Installation Notes | Clean and inspect the opening and plug before installation. Select the correct size, insert the plug evenly, and ensure full circumferential contact without damaging the rubber. Do not use a plug for pressure service unless its rated pressure and retention method are confirmed. |
|---|---|
| Maintenance Tips | Inspect for cracks, cuts, hardening, swelling, and permanent deformation before reuse. Clean with fresh water and mild detergent, dry thoroughly, and store away from sunlight, heat, ozone, oils, and sharp objects. |
| Safety Notes | Verify that the opening is safe to access and that pressure or trapped fluids have been released. Do not stand in line with a pressurized plug. Use suitable lifting and securing methods for large plugs, and confirm removal before vessel undocking or system commissioning. |
