Built from 6061-T6 aluminum and engineered for high-pressure use, the fitting integrates a 37° flare sealing surface and a plastic spring lock to help prevent accidental disconnection. It’s designed for applications like fuel rails, return lines, transmission coolers, and inline fuel sensors where reliable, serviceable connections matter.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adapter maintain a leak-resistant fuel connection?\u003c\/h3\u003e\n\u003cp\u003eThe fitting uses a 37° flare seat on the 6AN male thread to create a metal-on-metal seal when torqued correctly, minimizing potential leakage paths.
