The bottom line: this is a simple, durable sealing solution for technicians and DIYers who need reliable metal-to-metal seals on air conditioning, refrigeration, gas, or hydraulic lines. The gaskets are notable for being made of copper, which offers hardness, ductility, and corrosion resistance so that fittings maintain a leak-tight joint without frequent replacement.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCopper construction:\u003c\/strong\u003e The copper material gives wear resistance and hardness so gaskets maintain shape under repeated tightening.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/8 in tube size:\u003c\/strong\u003e Sized for 3\/8 in (9.52 mm) copper pipe with a 9 mm inner diameter for consistent fitting compatibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e45 degree flare design:\u003c\/strong\u003e Shaped for 45 degree flare fittings to produce reliable metal-to-metal seals on AC and refrigeration lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide compatibility:\u003c\/strong\u003e Works with brass, aluminum, chopper, and welded steel hydraulic tubing that can be flared, increasing its usefulness across systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12 pieces per pack:\u003c\/strong\u003e A dozen gaskets provides spare parts for routine maintenance and small installation jobs without frequent reordering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis product is aimed at HVAC and refrigeration technicians, mechanics, and informed DIYers who regularly work with flared copper tubing and need a dependable seal that resists corrosion and deformation.
