3mm O-Ring black, model accessory, 10-piece

This 10-piece pack of black 3 mm O-rings adds a practical spare-parts supply for model maintenance, repair work and small mechanical assemblies. Each ring shares the same compact diameter and circular form, making the set useful wherever a matching seal or replacement ring is needed to restore fit between moving or joined parts. The pack contains 10 identical rubber O-rings, which helps keep replacements consistent across repeated service jobs instead of mixing unmatched sizes. Their black finish makes them easy to distinguish from other small workshop parts during sorting and storage. In model building and accessory upkeep, small sealing components often matter as much as larger visible parts, especially when a worn ring needs a direct like-for-like swap rather than an improvised substitute. Kept in a parts drawer, tool case or bench organiser, these O-rings are ready for routine maintenance sessions and quick repairs. The uniform 3 mm format also suits builders who prefer to keep duplicate consumable parts available before starting detailed assembly or servicing work.
