Compression Fitting (Paperback)

High Quality Content by WIKIPEDIA articles! 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 also be made of one or more compatible materials appropriate for the connection. Compression fittings for attaching tubing (piping) commonly have ferrules (also known as olives) in them.
