The Norwesco 3 Inch Bulkhead Fitting is a polypropylene tank fitting that creates a serviceable 3-inch port through a tank wall. It measures 3 inches in diameter with a 4-inch overall envelope and weighs about 3 pounds. A bulkhead makes the connection where a pipe or valve passes through the wall, giving you a clean, serviceable penetration instead of a fixed molded outlet.
What it fits and how it installs
This is a field-trim fitting: cut the wall to the opening Norwesco specifies, then seat the bulkhead so it draws tight against the tank surface. The 3-inch size suits larger drain, fill, and discharge runs where a smaller port would choke flow. Confirm your wall thickness and hole size against Norwesco's spec before cutting - the seal depends on a correctly sized opening.
Material
Polypropylene resists moisture and general weather exposure and stays dimensionally stable in outdoor service, which is why it is a common choice for water-service tank penetrations. Match the fitting size to your plumbing rather than oversizing the port.
