Ayten Tube Fittings is a reputable manufacturer and supplier of Brass Hydraulic Fittings based in Addis Ababa, Ethiopia. We take pride in delivering precision-engineered, high-performance fittings that are perfect for fluid and gas transfer systems. Our Brass Hydraulic Fittings are crafted to ensure leak-free, durable, and corrosion-resistant connections in hydraulic applications. Made from top-quality brass, these fittings boast excellent machinability, strength, and the ability to handle high pressure. With a variety of configurations, including elbows, tees, couplings, and adapters, Ayten Tube Fittings guarantees compatibility with a broad range of hydraulic systems used in industrial machinery, automotive, and instrumentation applications.
Brass Hydraulic Fittings are mainly made up of copper (about 60–70%) and zinc (around 30–40%), with small amounts of lead to enhance machinability. These fittings showcase impressive tensile strength (350–500 MPa) and yield strength (200–300 MPa), ensuring they can withstand moderate to high pressure. Brass is known for its excellent corrosion resistance, particularly against water, fuels, and hydraulic oils, while also providing great thermal and electrical conductivity. The material’s natural malleability and ductility allow for precise threading and shaping, guaranteeing reliable sealing, mechanical stability, and a long service life in demanding hydraulic environments.
