An ingenious design from UK brass guru, Denis Wedgewood. This nifty water key eliminates the need for cork replacements, spring coil replacement, and ends leaky spit valves. Yes, you will never have to replace a cork again!
Encased in a black nylon ring is a stainless steel ball bearing that gives a 100% seal and gives a seamless gap where your spit valve would normally be. There is nothing to block the exit hole and can be engaged from 360 degrees. It is superior to the Amado: it is the fastest draining water key, it never wears out, and there are no parts that need to be oiled.
Also, the threaded pieces allow you to take it apart and clean it if you like. An easy installation by your favorite repairman and you are ready to go! Special installation instructions are available. Please make sure your repairman is aware of the proper installation method.
Note: Saturn water keys are no longer made with a brass outer ring as pictured on the instrument. The ring is now black-colored nylon.
