Yanmar O-ring for impeller pump cover – 119574-42570

Yanmar O-ring 119574-42570 is an original sealing ring for the cover plate of the seawater pump (impeller pump) on various Yanmar marine engines. This O-ring provides a watertight seal for the cooling system and prevents cooling water from escaping past the pump cover. A worn or damaged O-ring can lead to leaks, reduced cooling performance, and eventually engine overheating. The O-ring is manufactured from high-quality rubber that is resistant to high temperatures, pressure, and saltwater conditions.

Main features and benefits:

Watertight seal: Prevents cooling water leakage at the pump cover.
Protects the cooling system: Helps the cooling water pump operate at peak efficiency.
Resistant to marine conditions: High-quality rubber withstands salt water, pressure, and temperature fluctuations.
Ideal during impeller maintenance: Recommended when inspecting or replacing the impeller.
Original Yanmar part: Ensures a perfect fit and reliable sealing performance.
