Malleable fittings are called as such due to their physical property of malleability. This means they are easily deformed by hammering or rolling for example, without damaging or cracking the metal. This property is useful due to malleable fittings being used to connect steel or galvanised pipes. They can be used for steam, air, water, oil as well as other applications. We stock a range of malleable fittings from the trusted brand Crane.
