Vetus Air Vent Anti Syphon Device With Hose (AIRVENTH)
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.

- This version has a hose connection to the outside of the hull, there is a constant bleed off of cooling water through this hose while the engine is running
- Comes complete with a skin fitting (thru-hull), hose clamps and 4 meters (13') of hose
- Fits hose ID: 1/2", 3/4", 1" and 1-1/4"
- Width: 3.86" (98mm)
- Thickness: 1.97" (50mm)
