Hey gearheads, this is a specific hardware piece for your fuel system. This is a 5-pack of silver aluminum \olive\ inserts (sometimes called ferrules) for -8 AN size fittings. They're made from 6061 aluminum and are designed to be used with AN-style hose ends that work with PTFE (Teflon) lined stainless steel braided hose. The thread is 3/4\ x 16 UNF (JIC8). When you assemble the hose end, this olive gets compressed inside the fitting to create a tight, leak-proof seal around the hose. Essential for building or repairing high-performance fuel lines, oil lines, or other AN plumbing in cars, motorcycles, or race machines. Always make sure you're using the correct AN size for your hose and fittings.
