Metal Pumbing Fittings & Connectors
There are numerous fittings and adaptors available to joint together metal piping, listed below are a selection of the most common compression fittings, to make their recognition that little bit easier.
Compression joints are much simpler to use than capillary joints, which require heating and soldering to make them watertight, and can create a watertight joint in seconds. However they are more expensive than capillary joints, and in some confined spaces they are not not apllicable if one cannot get a wrench to turn the nut.
