Brass compression fittings are a fundamental component in plumbing and fluid transfer systems, prized for their reliability and ease of use. They create a secure, watertight seal by mechanically compressing a ring, or "ferrule," onto a pipe as a nut is tightened. This simple yet robust design requires no soldering, solvents, or specialized tools beyond standard wrenches. Constructed from durable, corrosion-resistant brass, these fittings are ideal for a wide range of applications, including potable water, natural gas, and hydraulic lines. Their versatility allows them to connect different types of pipe materials, such as copper, aluminum, and various plastics, making them an essential problem-solver for both new installations and repairs.
