About this item<\/h2>\n

Need a reliable AN-to-AN coupler to extend your fuel hose? AN Male to AN Male flare coupler union delivers 1,500 PSI leak-free performance in black anodized 6061-T6 aluminum alloy for DIYers and mechanics extending fuel lines, connecting fuel pumps, and building cooler systems.<\/p>\n

\"\"\"\"\"\"\"\"<\/p>\n

Precision 8AN to 8AN Male-to-Male Coupler Union<\/h3>\n

This fitting adapter features threads on both ends, providing a reliable straight union for connecting two AN lines. The accurately machined threads ensure a perfect match and secure connection when extending fuel hoses, building cooler systems, or connecting fuel pumps in automotive applications.<\/p>\n

37-Degree Flare Sealing for Leak-Free Performance<\/h3>\n

Both AN connections use a standard 37\u00b0 flare angle<\/strong>, creating a metal-to-metal seal that holds under high pressure without the need for thread sealant or PTFE tape. The precision-machined sealing angles ensure tight, consistent, and leak-free connections at both ends, maintaining stable system performance.<\/p>\n

6061-T6 Aluminum Alloy with Black Anodized Finish<\/h3>\n

Built from high-strength 6061-T6 aluminum alloy<\/strong> with a black anodized finish, this coupler fitting offers an excellent strength-to-weight ratio, corrosion resistance, and a professional appearance. The anodized coating provides additional protection against wear and environmental exposure in under-hood automotive environments.<\/p>\n

1,500 PSI Rating for Fuel System Applications<\/h3>\n

Rated for 1,500 PSI maximum working pressure<\/strong> and a temperature range from -65\u00b0F to 252\u00b0F (-53\u00b0C to 122\u00b0C)<\/strong>, this coupler is suitable for fuel hoses, fuel pump connections, cooler systems, and other high-performance automotive applications demanding reliable fluid transfer.<\/p>\n
