Yanmar O-ring for impeller pump cover – 119175-42570

Yanmar O-ring 119175-42570 is an original rubber sealing ring for the cover of the cooling water pump (seawater pump) on various Yanmar marine engines. This O-ring provides a watertight seal between the pump cover and pump housing, preventing cooling water leakage. A worn or damaged O-ring can lead to water loss, reduced cooling performance, and eventually engine overheating.

Main features and benefits:

Watertight seal: Prevents cooling water leakage at the pump cover.
Protects the cooling system: Helps maintain optimal operation of the cooling water pump.
Prevents overheating: Supports reliable engine cooling water circulation.
Original Yanmar part: Ensures a perfect fit and durable sealing performance.
Ideal for maintenance: Recommended when replacing the impeller or overhauling the cooling water pump.
