These heavy-duty 3/4-inch flare nuts are designed to provide a secure, leak-proof mechanical connection for copper tubing in various appliance and HVAC applications. Ideal for use in high-pressure environments, these brass fittings are essential for refrigeration systems, air conditioning units, and gas line installations. The flare nut works by drawing the flared end of a copper pipe onto a mating fitting, creating a tight seal without the need for soldering or welding. Built for durability and resistance to corrosion, these fittings are a standard choice for technicians and DIYers looking for reliable components in residential and commercial appliance repair.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
