Stainless compression fitting that adapts 3/8 inch OD tubing to a -6AN male connection. Includes the AN male body, compression sleeve, and compression nut. Works with stainless or mild-steel hard line and is commonly used for fuel systems, transmission coolers, and power-steering return tubes. Requires about 1 inch of straight tubing for proper assembly and provides a strong, leak-resistant seal once tightened.
