A “-3 AN Dbl Brake Line Bulkhead” is a double bulkhead fitting used to pass two -3 AN braided steel brake lines through a firewall or chassis panel.
It creates a secure, leak-free connection and is commonly used in motorsport and high-performance automotive applications. The fitting typically features a threaded body with two ports for the AN lines and a bulkhead nut to fasten it in place.Â
