Mechanical seals
Pump and auxiliary machinery seal assemblies, seal repair kits, lip seals and gland packing for shafts, and stern tube seals. A seal is identified by make and arrangement, not by the pump it sits in.

Consumables supplier
Small components become easier to source when the equipment route is clear.
Seals, gaskets and bearings often appear inside wider maintenance, overhaul and repair RFQs. Vessel Core structures the request around component type, equipment context, quantity and available evidence.
Useful starting points include part numbers, removed-part photos, dimensions, nameplates, old offer lines, invoice references, packing list references, drawings or Excel maintenance lists.
Supply scope
Consumable and cross-check items that belong in this RFQ route.
Coverage stays broad enough for real vessel purchasing, but focused enough for technical routing.
Gasket sets
Overhaul gasket sets for strip-down and rebuild, flange gaskets in non-asbestos sheet or spiral wound, cover and casing gaskets, copper and aluminium sealing washers, and kit references from the part book.
O-rings and packing
O-rings and seal rings ordered by inside diameter, cord diameter and elastomer — nitrile, fluorocarbon, EPDM — and gland packing by section, length and type. Three numbers and a material settle most of these without a part number at all.
Bearings
Main and crankpin bearing shells, thrust bearings, and bearings for pumps, electric motors and auxiliary equipment. For shells the request has to state nominal or undersize — that single word decides which part number applies.
Filters
Oil, fuel and hydraulic filter elements, given with the filtration rating in microns and the connection dimensions, plus separator filter elements and consumables tied to service work.
Service kits
Grouped consumables for scheduled maintenance, overhaul or repair. A kit reference is worth more than its contents listed loose, because it fixes what the maker intends to be replaced together.
Evidence guide
Old commercial documents can help, but private details stay private.
An old offer, invoice or packing list can reveal the useful commercial wording, component grouping and quantity logic. Vessel Core uses that context internally and does not publish customer, order or supplier private details.

Why Vessel Core
Consumables are checked against the equipment, not against a name.
OEM routes and verified alternatives are weighed on the part evidence, the buyer's approval requirements, the documentation available and the vessel's schedule. Availability and route are confirmed only after the RFQ is reviewed.
Matching without a part number
Where no exact number exists, matching can start from a photograph, dimensions, a marking, the equipment nameplate, a drawing or a part-book page. The designation is confirmed at RFQ stage rather than assumed.
OEM or alternative is the buyer's call
An OEM-route review can be requested where class requirements or heightened documentation requirements apply. Verified alternatives are reviewed for running spares, with documentation requirements checked at RFQ stage.
Long consumable lists
Excel tables, service-kit schedules, packing-list wording and lines from a previous offer all help structure a request that runs to dozens of items.
Assessed at RFQ stage
Availability, supply route and logistics are assessed against the part specification, the buyer's approval requirements, the vessel ETA and the destination port.
Port-aware planning
Route, handover option and freight timing are reviewed against confirmed RFQ details. No fixed delivery commitment is made before availability and route are confirmed.
An EU legal entity
Vessel Core OÜ is registered in Estonia, registry code 17028043, VAT EE102773714 — public details, a named RFQ contact and a documented way for a buyer to verify the company.
Consumables FAQ
Seals, gaskets and bearings — common questions
Can a seal, gasket or bearing be requested without a part number?
Yes. A photograph, dimensions, the equipment maker and model, a previous order reference, a part-book page or the marking on the removed part are enough to start matching. The exact designation is confirmed at RFQ stage.
Can a grouped consumables list be sent?
Yes. Excel tables, service-kit schedules, packing-list wording and lines from a previous offer all help structure a large consumables request.
Are verified alternatives reviewed for seals and bearings?
Yes. For running spares and planned maintenance both OEM-route and verified alternative routes are reviewed. Where class requirements or heightened documentation requirements apply, an OEM-route review can be requested.
Are old commercial documents used when matching?
A previous offer, invoice or packing list helps recover the line wording, the grouping of components and the quantity logic. That context is used internally; private buyer, order and supplier details are not published.

Have seals, gaskets, bearings or filters to source?
Send maker/model, part reference, quantity, evidence and port/ETA. Old commercial documents are useful when part wording or grouping is unclear.
