Built from 6061-T6 aluminum with a plastic spring-lock sleeve and a 37° sealing flare, it’s made to perform in automotive fuel rails, LS swaps, transmission coolers, return lines and inline sensors. The fitting is rated to 1500 psi and works across a wide temperature range, making it a durable option for many under-hood and fluid-transfer applications.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this fitting create a leak-resistant connection?\u003c\/h3\u003e\n\u003cp\u003eThe connector uses a 37° flare seal at the 6AN interface and a spring-lock mechanism on the 3\/8\" side to reduce the risk of leaks. The mating surfaces are machined to align the flare and the push-on sleeve for consistent sealing under pressure.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e37° flare sealing angle for tight metal-to-metal contact\u003c\/li\u003e\n  \u003cli\u003ePrecision-machined 9\/16-18UNF 6AN thread for reliable torque\u003c\/li\u003e\n  \u003cli\u003eSpring-lock female sleeve secures push-on hose fittings quickly\u003c\/li\u003e\n  \u003cli\u003eSingle-piece sealing geometry minimizes potential leak paths\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat pressure and temperature limits should I expect?\u003c\/h3\u003e\n\u003cp\u003eThis adapter is specified for working pressures up to 1500 psi and tolerates temperatures from -40°F to 176°F, covering most automotive fluid system conditions short of extreme thermal environments.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eWorking pressure: 1500 psi rating for high-pressure circuits\u003c\/li\u003e\n  \u003cli\u003eOperating temperatures: -40°F to 176°F for general automotive use\u003c\/li\u003e\n  \u003cli\u003eSuitable for common fuels and transmission fluids within temperature limits\u003c\/li\u003e\n  \u003cli\u003eNot intended for extreme high-heat exposure beyond specified range\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials are used and why do they matter?\u003c\/h3\u003e\n\u003cp\u003eThe body is machined from aluminum alloy 6061-T6 for strength, light weight and corrosion resistance, while the spring-lock sleeve is plastic to allow smooth push-on operation and secure retention.

This fitting is aimed at automotive builders, mechanics, and enthusiasts who need a compact, high-pressure quick-disconnect for fuel or fluid systems. It suits projects where a robust 6AN connection must interface with 3\/8\" spring-lock hoses, especially in engine swaps, retrofit cooling circuits, or custom fuel-return configurations. If you require a heavy-duty, service-friendly adapter rated to 1500 psi with reliable 37° flare sealing, this EVIL ENERGY connector is designed for that role.\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: What thread size does this adapter use?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The male thread is 6AN (9\/16-18UNF) and mates to standard 6AN flare ports.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is the fitting suitable for fuel system use?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it's designed for fuel and fluid lines with a 37° flare seal and a 1500 psi rating.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"EVIL ENERGY","offers":[{"title":"Default Title","offer_id":55161006752087,"sku":"B08QMXJJHB","price":30.62,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/evil-energy-front-view-fitting.jpg?v=1790320597","url":"https:\/\/britishgarage.co.uk\/products\/evil-energy-6an-male-to-3-8-inch-quick-disconnect-push-on-fitting-1500-psi-6061-t6-aluminum","provider":"British Garage","version":"1.0","type":"link"}
