Manufactured from lightweight yet extremely strong 2024 aluminum, this coupling provides excellent durability without adding unnecessary weight to your vehicle or equipment. The black anodized finish enhances corrosion resistance, ensuring dependable operation even in demanding performance or industrial environments. This NPT coupling is ideal for situations requiring a secure, threaded connection between fluid components. Since NPT fittings seal on the threads, PTFE tape or sealing compound must be used during installation for a leak-free result. When installed correctly, this adapter is suitable for custom fuel systems, hydraulic setups, oil lines, pressure instrumentation, and general-purpose fabrication.\u003c\/p\u003e\n\u003cp\u003e𝗙𝗲𝗮𝘁𝘂𝗿𝗲𝘀:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePrecision-machined 3\/8\" NPT male-to-male coupling adapter\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBlack anodized finish for superior corrosion resistance\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLightweight 2024 aluminum construction for long service life\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eIdeal for fuel, oil, hydraulic, and multi-purpose plumbing applications\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThreaded design requires PTFE tape or sealant for proper sealing\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eSuitable for custom builds and performance plumbing situations\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Earls","offers":[{"title":"Default Title","offer_id":45944373444807,"sku":"ERLAT991103ERL","price":20.44,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/2277\/5751\/files\/ERLAT991103ERL.avif?v=1765355091","url":"https:\/\/mainstreeteshop.com\/products\/earls-3-8-npt-male-to-3-8-npt-male-coupling-adapter-black-anodized-aluminum","provider":"MAIN STREET ESHOP","version":"1.0","type":"link"}
