A fuel tank breather valve is an essential element of the fuel tank on your boat. This is a crucial aspect to fuel ventilation, and allows the tank to breathe. The valve allows air to escape the tank so that it can continue to function at full capacity. Over time, under pressure, these valves wear and need replacement. If you are in this position, the Breather Poly 15mm is for you. A replacement for 15mm hoses, this valve is made from corrosion-resistant polypropylene, which makes it durable and long-lasting, which is ideal for aluminium boating usage. Even if your valve doesn’t need replacement, it is a wise idea to have one ready at your convenience for when the situation does arise. The Breather Poly is simple, effective and a reliable part that keeps everything running smoothly.
