Offered high quality Brass Compression Fittings are used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connection. Compression fittings are one of the most common and versatile methods of connecting metal or hard plastic tubing. They are particularly useful for their extreme temperature and pressure capabilities, and their compatibility with aggressive fluids. The offered Brass Compression Fittings are very efficient and useful.
