Vetus Air Vent Anti Syphon Device With Hose

The Vetus anti syphon device helps to prevent cooling water from siphoning back into the exhaust and ultimately into the engine when it is off. This is critical on boats where cooling water is injected into the exhaust less than 6 inches above the waterline.
