A bulkhead fitting allows piping connections to a tank. A hole is cut in the tank into which the fitting body is inserted. Locknut threads onto the body to hold it in place. The locknut puts pressure on the gasket(s), allowing it to make a tight liquid seal.
Bulkhead should be hand tightened and then another 1/4 to 1/2 turn. Over-tightening may distort the gasket and cause leaks.
