This repair kit for Martec vacuum (anti-siphon) valves fits all valve sizes (12–25mm), so a single spare-part number covers valves of every size. The kit includes the cap and rubber valve — the two parts that typically wear out or age first over time, causing the valve to leak or stop working reliably. An affordable way to service an existing vacuum valve yourself without replacing the whole unit.
- Fits all Martec vacuum valve sizes (12-25mm)
- Includes cap and rubber valve
- Affordable alternative to replacing the whole valve

Martec's 12mm vacuum (anti-siphon) valve is a safe, reliable protective component for your boat's engine. It's designed to effectively prevent siphoning in the engine's exhaust outlet — a phenomenon where, after the engine shuts off, water can be drawn back into the engine through the exhaust and cause severe, potentially engine-destroying damage. The valve is made from corrosion-resistant materials, fully leak-proof, and designed for easy installation even in tight engine bays.
This 12mm model is compatible with Yanmar YSE8-12 (raw-water cooled) and 1GM (raw-water cooled) engines, giving lasting protection that preserves engine function and lifespan. A popular spare part for Yanmar engine servicing and replacing worn-out valves.

Martec's 16mm vacuum (anti-siphon) valve is a safe, reliable protective component for your boat's engine. It effectively prevents siphoning in the engine's exhaust outlet — a phenomenon that can otherwise draw water back into the engine and cause serious damage while the engine is off. The valve is made from corrosion-resistant materials, fully leak-proof, and easy to install even in a tight engine bay.
This model fits a wide range of Volvo Penta engines (MD1, 2, 3, 5, 6, 7, 11, 17, MB10, MD2001, 2002, 2003) and Yanmar engines (YSE8-12 fresh-water cooled, YSB8-12, YSM8-12, 1GM fresh-water cooled, 2GM, 3GM, 2QM15, 2QM20). Always check your exact engine model before ordering, as older Volvo Penta and Yanmar models use different valve sizes.
