Built from 6061-T6 aluminum with an anodized black finish and an NBR O-ring, it balances corrosion resistance and light weight while maintaining a rated working pressure suited for many automotive fluid systems. Use it when you need a reliable transition between imperial flare fittings and M18x1.5 ports without welding or hose re-routing.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adapter create a leak-resistant connection?\u003c\/h3\u003e\n\u003cp\u003eThe adapter combines a 37° AN flare sealing surface on the 6AN side with a compressed O-ring seal on the M18x1.5 metric thread side. Metal-to-metal flare contact prevents weeping at the AN joint, while the O-ring provides elastomeric sealing for metric ports that rely on radial compression.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e37° flare seat on 6AN side for traditional AN sealing\u003c\/li\u003e\n  \u003cli\u003eNBR O-ring on metric side to seal threads without thread tape\u003c\/li\u003e\n  \u003cli\u003ePrecision machining for concentric seating and uniform compression\u003c\/li\u003e\n  \u003cli\u003eAnodized surface reduces corrosion that can compromise seals\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs this fitting strong enough for power steering systems?\u003c\/h3\u003e\n\u003cp\u003eThis adapter is rated to 1500 PSI and rated for a broad temperature range, making it suitable for many power steering and low- to mid-pressure fuel-system applications.

It suits those doing repairs, custom hose builds or retrofits on power steering systems and many fuel-system tasks where a threaded metric port must accept an AN-style line. If you require fittings rated above 1500 PSI or for very high-temperature fluids, consult system specifications or consider a higher-rated solution.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this adapter fit my power steering rack?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It fits racks with an M18x1.5 female port and 6AN lines; verify your port thread and flare size before buying.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use thread sealant or tape on the metric side?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Usually not needed—the O-ring provides the seal.
