Sea Star Solutions Impeller - Mercury - Sierra Marine Engine Parts (18-8900)

The clamping pressure surrounding the combustion chamber is increased using an O-Ring.

The 18-7145-9 O-RING from Sea Star Solutions is designed to improve cylinder sealing in high-pressure situations. The metal parts encircle the bore and chamber, improving the head gasket's ability to seal. An O-ring is a gasket that joins two surfaces through a circular loop. The oil can run into the valve guides, which are burned inside the combustion chamber if this small and otherwise uncomplicated component is absent.

Key Features

• Can resist the most pressure when sealing.
• Two working surfaces are naturally compressed and sealed by high-performance sealing power, preventing air or liquid leakage.
• O-rings are a great option since they can withstand high temperatures and are resistant to moisture, silicone, steam, and oil.
• It does not deteriorate.
• Five pieces come in each pack.
