Machined from 6061-T6 aluminum and finished in anodized black, each adapter seals at the AN flare face (37°) while the NPT end uses a tapered 60° thread. These fittings are commonly used in automotive fuel systems, cooling lines, and power steering plumbing where a transition from AN flare tubing to NPT threaded ports is required. For leak-free results on the NPT side, use thread sealant or PTFE tape.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I confirm compatibility with my lines and ports?\u003c\/h3\u003e\n\u003cp\u003eCheck both the AN and pipe-thread sides before installation: the adapter uses a standard 6AN male flare (9\/16-18 UNF) on one end and a 1\/4\" NPT tapered thread on the other. Verify mating parts for matching thread forms and diameters to avoid cross-threading or poor sealing.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAN side: 6AN male flare, 9\/16-18 UNF thread.\u003c\/li\u003e\n  \u003cli\u003eNPT side: 1\/4\" tapered pipe thread, 60° sealing angle.\u003c\/li\u003e\n  \u003cli\u003eConfirm port type (flare vs. pipe thread) on vehicle or component.\u003c\/li\u003e\n  \u003cli\u003eMeasure tubing outer diameter and thread pitch if unsure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and finishes are used, and why does it matter?\u003c\/h3\u003e\n\u003cp\u003eThese adapters are machined from 6061-T6 aluminum and anodized black for improved surface hardness and corrosion resistance.

Mechanical hobbyists, performance tuners, and technicians who install or adapt fluid lines will appreciate this economical 4-pack of AN6-to-1\/4\" NPT adapters. If you need to convert a 6AN flare line to a 1\/4\" NPT threaded port with a lightweight, corrosion-resistant fitting, these EVIL ENERGY adapters provide a straightforward option — just remember to use proper thread sealant on the NPT side for leak-free operation.\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: Does the AN6 end seal on its own?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—the 6AN male flare seals by its 37° flare face against a mating female flare; no thread sealant is needed on the AN side.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is thread sealant required on the 1\/4\" NPT side?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—use PTFE tape or a compatible thread sealant on the 1\/4\" NPT tapered threads to ensure a leak-free connection.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"EVIL ENERGY","offers":[{"title":"Default Title","offer_id":48087019258014,"sku":"B0BPSC7VGB","price":34.23,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/evil-energy-an6-to-1-4npt-front-view.jpg?v=1785914113","url":"https:\/\/northtrailauto.ca\/products\/evil-energy-6an-male-flare-to-1-4-npt-pipe-fitting-adapter","provider":"North Trail Auto","version":"1.0","type":"link"}
