This is the finished product after a few seasons use. These seacocks are for; head sink, macerator pump & head intake. I prefer to use heavy duty mandrel formed marine hose, such as Trident or Shields, for all below waterline connections. I also prefer to use AWAB non-perforated hose clamps & I always double clamp for below water applications.
Remember to close your seacocks when you leave the boat. The best way to ensure your seacocks will last and work as they should, for years and years, is to simply use & exercise them.
