Machined from 6061-T6 billet aluminum and finished with a black anodize, each fitting includes an internal brass ferrule and a compression nut to secure aluminum, stainless steel, or copper hardline without flaring the tube end. They are commonly used in fuel, oil, transmission, and power steering plumbing when adapting factory or custom hard lines to aftermarket AN hoses.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these adapters attach to hardline tubing?\u003c\/h3\u003e\n\u003cp\u003eThese are compression-style fittings: the tube slides through a ferrule and compression nut and seats into the fitting body. Tightening the nut compresses the ferrule against the tube and fitting, forming a mechanical seal without the need for flaring.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSlide ferrule and nut onto the tube before insertion\u003c\/li\u003e\n\u003cli\u003eFully seat the tube until it bottoms in the fitting body\u003c\/li\u003e\n\u003cli\u003eTighten the compression nut to compress the brass ferrule and seal the joint\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and finishes are used and why do they matter?\u003c\/h3\u003e\n\u003cp\u003eThe adapters are milled from 6061-T6 billet aluminum for strength and light weight, with a black anodized finish that provides corrosion resistance and a uniform aesthetic.
