Extending copper pipes doesn't have to mean breaking out the welding torch. With this flare connector set, you simply align the flared pipe ends to the thread and tighten the flare nuts by hand or with a wrench for a secure connection—it really is that easy. Made from solid brass, these connectors offer the corrosion resistance, strength, and toughness needed for a long-lasting connection you can count on. They're ideal for air conditioning systems, HVAC projects, refrigeration equipment, water pipe systems, and industrial pipelines, working just as well in residential settings as in commercial and industrial applications. The set includes two connectors designed for 3/4-inch and 3/8-inch outer diameter copper pipes, so you always have the right size on hand for a variety of pipe connection needs. One quick tip before you get started: slide the flare nuts onto the copper pipes first, then flare the ends of the pipes—this simple step order makes installation go smoothly. Durable, versatile, and hassle-free, this set takes the hard work out of pipe extension.
