The Vintage Air Extended 90-Degree Heater Fitting is an extended-reach bulkhead-style fitting that connects 5/8-inch heater hose to a -10 AN female O-ring port at a 90-degree angle. The added length helps it clear firewalls and tight sheet metal where a standard 90-degree fitting will not reach. It is machined from aluminum with a natural finish.
