GH-6022 Brass compression fittings
A brass compression fitting is a robust, leak-resistant connector used to join aluminum-plastic pipes or tubing in plumbing, hydraulic, pneumatic, or gas systems. Constructed from brass—a durable copper-zinc alloy—it resists corrosion, high pressure, and temperature fluctuations, ensuring long-term reliability. The fitting typically consists of a brass body, a compression nut, and a ferrule (sleeve) that tightens around the tube when the nut is screwed onto the body, creating a secure, watertight seal without soldering or welding. Its design allows easy installation and disassembly, making it ideal for repairs or modifications. Brass compression fittings are compatible with various materials, including copper, plastic, and stainless steel tubing, and are widely used in residential plumbing, industrial machinery, refrigeration, and fuel lines. They offer excellent vibration resistance, maintain integrity under stress, and require minimal maintenance, though proper alignment and torque during installation are critical to prevent leaks. While slightly more costly than plastic alternatives, their durability, reusability, and adaptability to harsh conditions make them a cost-effective choice for critical fluid or gas systems.
