Marine O-rings, gaskets and seals sourcing for technical RFQs

Component-focused RFQ support for marine and industrial buyers working from part numbers, old parts, photos, drawings or equipment references.

Component-based sourcing

RFQ review for purchasers, engineers and repair teams

O-rings are sized under two systems that aren't interchangeable — AS568 (US dash numbers, e.g. -212) and metric/BS1806 (ID × cross-section in mm). A metric O-ring sits loose or overstretched in an AS568 gland even when the numbers look close, so confirming the ID, cross-section and standard (not just 'the size off the old part') matters. We review RFQs for pumps, engines, heat exchangers, doors, valves, compressors and hydraulic systems when buyers can provide dimensions, material, part numbers or sample photos.

Send the part number, maker, equipment model, serial number, quantity, photos, drawings, nameplate, old offer, old invoice reference, delivery location and required delivery time. The more technical context you can provide, the faster the request can be checked.

We support component RFQs from vessels, shipyards, repair companies, vessel managers, industrial plants and maintenance teams.

What we can review

Component examples

O-rings

O-rings are matched by shaft size, material and dimensions rather than by name, so a marked drawing or old part helps.

gaskets

For gaskets, dimensions and material (NBR, Viton, PTFE) are usually enough to identify the right item.

seal kits

Seal kits are matched by shaft size, material and dimensions rather than by name, so a marked drawing or old part helps.

gasket sets

Gasket sets are matched by shaft size, material and dimensions rather than by name, so a marked drawing or old part helps.

pump seals

For pump seals, dimensions and material (NBR, Viton, PTFE) are usually enough to identify the right item.

door seals

Door seals are matched by shaft size, material and dimensions rather than by name, so a marked drawing or old part helps.

valve seals

For valve seals, send the body size, port connection and pressure class where known, plus a nameplate photo if available.

compressor gaskets

For compressor gaskets, dimensions and material (NBR, Viton, PTFE) are usually enough to identify the right item.

heat exchanger gaskets

For heat exchanger gaskets, dimensions and material (NBR, Viton, PTFE) are usually enough to identify the right item.
