Package contains 4 brass double fittings with 1/2" and 3/8" male ends. The outer diameter of the large end is 20mm and the inner diameter is 17mm. The outer diameter of the small end is 15mm and the inner diameter is 11mm. Please measure the hose size before purchase to avoid leakage or installation failure. The double connectors are made of high quality brass, resistant to corrosion, rust, high temperatures, and with low magnetic permeability. It is more durable than traditional stainless steel or plastic threaded plugs. This brass double connector is easy to install and use, the twisting process is smooth and fluid, and the connection is tight and secure after installation. Note: for fittings without joints on the threaded end, sealing products such as hemp or sealing tape must be used. This hose connector is suitable for plumbing systems, heating systems and water pipe installations. It can be used for drinking water. Well-sealed threads ensure durable, leak-free pipe connections. double-head G1/2 and G3/8 inch brass caps are uniquely formed by precision forging technology, with a thickened structure, corrosion resistance, rust resistance, burst resistance, and external pressure resistance. Even in high temperature environments, due to the ductility of brass, it will not loosen or break apart easily.
