Chrome Plated Fittings

Chrome Plated Compression fittings are used if working in confined spaces where copper pipe would be difficult to solder and where a better finish is required in exposed installations
The fittings are composed of an outer compression nut and an inner compression olive that is typically made of brass or copper. Olives vary in shape and material but are most commonly in the shape of a ring with beveled edges
Thread sealants such as joint compound and thread seal tape (such as PTFE tape) are unnecessary on compression fitting threads, as it is not the thread that seals the joint but rather the compression of the olive between the nut and pipe
It is critical to avoid over-tightening the nut or else the integrity of the compression fitting will be compromised by the excessive force. If the nut is overtightened the olive will deform improperly causing the joint to fail
