It joins 3/8-inch outside diameter nylon tubing to a 3/8-inch NPT threaded port using a push-to-connect design that speeds up installation and eliminates the need for clamps. You typically replace this fitting when the original becomes cracked, stripped, or develops an air leak, which can lead to brake system pressure loss.
