Brass compression fittings offer a robust and reliable method for joining PEX (cross-linked polyethylene) pipes without requiring specialty tools, heat, or soldering. These durable fittings consist of a brass body, a compression nut, and a ferrule or ring that clamps down on the pipe. As the nut is tightened, it compresses the ring onto the PEX tubing, creating a strong, watertight seal against the fitting's body. The inherent strength and corrosion resistance of brass ensure long-term durability and safety, making them ideal for both repairs and new installations in potable water and hydronic heating systems. Their primary advantage is the simplicity of installation and the ability to be disassembled, providing a secure and serviceable connection.
