Extra long bulkhead fitting (aka tank adapter) in 1-˝" and 2", the cost is $39.95 for up to 12" long. If you need more than 12", the cost will be individually quoted, please email us. For less than 12" wall thickness, you can order them directly on this page. Since there are 2 ends of every bulkhead fitting and each end can have 1 of 2 methods of attachment that means there are 4 possibilities. You will specify this below. Thank you.
