Sierra O-Ring, Pack of 5, Part Number 18-7193-9

The Sierra O-Ring, part number 18-7193-9, is a rubber sealing ring sold in a pack of 5. Rubber O-rings like this one are used throughout marine engines and drive systems to create a tight seal between mating parts, such as housings, fittings, caps, and fluid passages, helping to prevent leaks of water, oil, or fuel at the sealed joint. Because O-rings are wear items that harden and lose their seal over time, keeping a pack of 5 on hand makes it easy to replace one during routine maintenance or a repair without having to reorder for a follow-up job. Each ring in the pack of Sierra O-Ring 18-7193-9 is made of rubber, a flexible material chosen for O-ring applications because it compresses into the gap between two surfaces to form a seal while resisting the moisture and fluids typically found in marine environments. The compact package dimensions and light package weight make this a simple, low-cost item to add to an onboard spares kit or maintenance toolbox.
