Yanmar Bonnet Gasket

Seals the joint between two surfaces so coolant, oil, compression or exhaust gases stay where they belong. Fit a new gasket any time the joint is opened up — a reused gasket invites leaks.

This is the genuine Yanmar Gasket, Bonnet (part number 119578-11360).

Genuine OEM part, despatched from our Melbourne warehouse — prices include GST.

30-day no-fuss returns. If you opened the box and the part doesn't fit, send it back unused within 30 days for a full refund. We'll cover return freight on our error; you'll cover it if the part was correct as ordered.

12-month warranty. Manufacturing defects covered for 12 months from purchase date. Wear-and-tear (impellers degrade with use — that's their job) is not covered, but reach out if something fails early and we'll work it out with the manufacturer.

Australian Consumer Law applies in addition to the warranty above.
