One of the components of a compression fitting; the conical piece of metal or plastic that compresses onto the tube as it is forced into a tapered seat. Valco metal ferrules are unique in that they attach to and seal at the tube by cutting a shallow ring into it, instead of by actually swaging it. This is preferable since it introduces no flow restriction.

The fitting at the bottom of a stick to reduce wear and prevent slipping. Traditional British types are a brass cup with a steel tip, although they can be made from a variety of materials.

the decorative plastic device found at the end of the hosel; common. on irons, although some, notably Ping, do not contain a ferrule filament-wound graphite shaft: strands of pre-preg are wound intricately around a mandrel, like so many strings of spaghetti; the process is controlled by a computer and can be repeated endless times.
