How does a bulkhead fitting work?

A bulkhead fitting allows piping connections to be made to a tank. A hole is cut in the tank into which the fitting body is inserted. A locknut threads onto the body to hold it in place. The locknut puts pressure on the gasket(s) that allows it to make a liquid tight seal.  

Bulkhead should be hand tightened and then another 1/4 to 1/2 turn. Over tightening may distort the gasket and cause leaks.
