O-Ring (Pack Of 2) - Sierra Marine Engine Parts (18-7481-9)

Compression between two pieces is effectively well-handled by a mechanical gasket acting as an O-ring. It is strategically well-placed within grooves. When this succeeds in forming a seal, they turn into one of machine design's most widely employed seals. O-rings' primary purpose as a sealing mechanism is to prevent liquid or air leaks. When squeezed between two surfaces, the ring takes up space and stops any fluid or air from escaping. They also maintain their shape, so they will immediately return to their previous state upon release. O-rings have a memory that allows them to expand in the opposite direction when pressure is applied, allowing them to seal with low or no stress.

Key Features:

• This replacement O-ring is the best approach to fix and stop leaks in your pump.
• It also lessens the required torque and wears on other vital components.
