Brand: Aeromotive Fuel Systems
This black anodized adapter is similar to the AN921-Style Adapter (Part No. 3287-10-10), but instead of using a bulkhead nut and backup washer to clock the fitting, this version has a swivel on the O-ring boss end. This lets you rotate the fitting after installation without having to loosen or re-tighten anything. Sold individually. Includes O-ring.
