Double ferrule tube fittings allow the connection of two imperial tubes (or fractional tubes), two metric tubes or, also, the connection of a metric tube at one end and a fractional/imperial tube at the other end.
A common size range is between 1/16″ and 2″ for fractional sizes and between 2 and 50 mm for metric sizes).
Double ferrule tube fittings are rated to the maximum working pressure of the tubing to be installed.
Double ferrule tube fittings are largely used across multiple industries, such as downstream petrochemical, pulp & paper, laboratories, aeronautical and shipbuilding, defence, power generation, semiconductors manufacturing, and heavy industries.
Double ferrule tube fittings (ferrule) can be grouped into the following families:
- Connectors (male connector, female connector, bulkhead male connector, bulkhead female connector, butt weld pipe connector, socket weld tube connectors)
- Male and female elbows
- End closures (tube, fitting)
- Reducers
- Tees (male run tee, female-run tee, male branch tees, female branch tees)
- Unions
