Forged construction delivers greater strength and pressure resistance than cast alternatives, making this nut a reliable choice for field connections that must hold up under vibration and thermal cycling. HVAC technicians and plumbers reach for this fitting when terminating or extending flare-type lines in both new construction and service work.\u003c\/p\u003e\n\u003cp\u003eThis flare nut is suited for residential and light commercial applications where 3\/8-inch OD copper or compatible tubing is used. Common installation scenarios include refrigerant line sets, fuel gas connections, and water supply lines that require a flared mechanical joint. The long-body design provides additional thread engagement, which helps maintain a stable connection at joint points that may experience movement or vibration over time.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eForged construction for superior strength and pressure resistance compared to cast fittings\u003c\/li\u003e\n  \u003cli\u003eLong-body design provides increased thread engagement for a more stable flare joint\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/8-inch OD tubing, a common dimension in HVAC and refrigeration line sets\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard SAE 45-degree flare connections typical in trade applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for systems using 3\/8-inch OD flare-type connections in HVAC, refrigeration, and plumbing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber following applicable local codes and manufacturer guidelines. Always de-pressurize and isolate the line before removing or installing any flare fitting. Use a calibrated flaring tool to prepare the tubing end before seating the nut, and tighten to fitting specifications using a properly sized flare wrench to avoid over-torquing the soft tubing. Inspect the flare seat for deformation or debris before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubing OD\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Style\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Forged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Flare Nut\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HOLYOKE FITTINGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 41 fpl-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLYOKE FITTINGS","offers":[{"title":"Default Title","offer_id":51468578160946,"sku":"41 FPL-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945144.png?v=1783918095","url":"https:\/\/voomisupply.com\/products\/holyoke-fittings-41-fpl-6-long-forged-flare-nut-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
