With a 5\/16 inch outside diameter and a 0.7 mm wall, the tube arrives coiled for easy storage and is suited to cutting, bending, flaring and polishing. It’s specified for a maximum working pressure of 650 psi and accepts common tube nuts, sleeves and 37° AN flared fittings, making it a flexible choice for many vehicle and equipment installations.\u003c\/p\u003e\n\n\u003ch3\u003eWhat are the key dimensions and pressure limits of this tubing?\u003c\/h3\u003e\n\u003cp\u003eThe tube measures 5\/16 inch (7.93 mm) outside diameter with a 0.7 mm wall thickness and comes as a 25‑foot (7.62 m) coil. Its maximum recommended working pressure is 650 psi, suitable for numerous low‑ to mid‑pressure fluid applications. These specs help determine compatibility with fittings and routing clearances.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOutside diameter: 5\/16\" (7.93 mm)\u003c\/li\u003e\n  \u003cli\u003eWall thickness: 0.7 mm\u003c\/li\u003e\n  \u003cli\u003eCoil length: 25 ft (7.62 m)\u003c\/li\u003e\n  \u003cli\u003eMax working pressure: 650 psi\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the 3003 aluminum alloy perform for fuel and fluid lines?\u003c\/h3\u003e\n\u003cp\u003eExtruded from 3003 grade aluminum, this tubing combines light weight with good corrosion resistance and ductility. The alloy allows straightforward manual bending, trimming, and flaring without cracking, while resisting common corrosion mechanisms found in vehicle and equipment environments.
