They provide an OEM-style threaded connection rated for demanding automotive and racing environments, and come as a pack of four for multiple installations or spares.\u003c\/p\u003e\n\n\u003ch3\u003eWhat makes these 12AN weld bungs suitable for fuel and fluid systems?\u003c\/h3\u003e\n\u003cp\u003eThe fittings are crafted from aircraft-grade 6061-T6 aluminum for a strong, lightweight connection that resists corrosion. The AN thread flares to a precise 37° seat, creating a metal-to-metal seal when mated with compatible AN fittings, and the parts are engineered to handle high pressures typical of automotive systems.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMaterial: 6061-T6 aluminum alloy for strength and low weight\u003c\/li\u003e\n  \u003cli\u003eSealing: 37° AN flare for metal-to-metal sealing\u003c\/li\u003e\n  \u003cli\u003ePressure rating: up to 1000 PSI (68.94 bar)\u003c\/li\u003e\n  \u003cli\u003eTemperature range: -65°F to 252°F for broad application use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I install these weld-on bungs correctly?\u003c\/h3\u003e\n\u003cp\u003eThese bungs are designed to be welded into a tank or tube wall; prepare a flush, clean surface and tack-weld in place to avoid warping.
