This is a brand new Spartan Seacock. These are wonderful and expensive products that can last well into 30+ years. According to Paul at Spartan the "average" life he sees is 30 years. Keep in mind though that many of these "average" valves have not been routinely maintained.


Tapered cone seacocks if cleaned & greased yearly, and lapped when needed, can likely out last you. Sadly many don't service them regularly and they then need replacement sooner.


These seacocks were installed by many reputable builders such as Sabre, Pearson, Tartan, C&C, Cape Dory, Bristol, Hinckley, Morris, Shannon Yachts and others. Today very few builders other than Robinhood/Cape Dory and Shannon still use them though there are a few Down East Maine builders who will still use nothing but. With price competition the way it is builders have moved to less expensive, though not necessarily better, alternatives.
